Jammy git!!!


noise is the wonderful kawasaki clutch rattle...as standard from the factory..

550 was underrated but still a good bike..search ebay for the 750 fairing which will make riding it a bit more pleasurable

Update! At last. Embarassed Told you it would be slow. Laughing

I snapped a banjo bolt in the caliper putting it back together. Luckily, the head snapped off before the bolt was tight, so I could slowly wind it out with the tiny bit of thread sticking out the end. So new banjo bolts all round.

I have got new brake pistons and seals in and new pads. I have bled the front brakes about 4 times now, they are better than they were but the lever will still come all the way back to the bar. Were they always like this on these bikes, does anyone know? My Varadero does it as well but you never need to squeeze the brakes on much harder than halfway on that bike. A test ride is needed.

Another thing is that these screws on the front brake reservoir are knackered. The things are starting to round off and if I want to get them out, I have to use the impact driver to do so every time. even if I just put them back loosely. Can I get new ones any where? Will anything with the same thread work?

Here's the oil that came out of her Sick

https://i1302.photobucket.com/albums/ag134/Fladdem/P7130174_zps79cb1d6f.jpg

ALso, while fiddling around and checking her over, I spotted this wobbly sprocket, never had a cush-drive before, is it meant to do this? What may be causing it, what should I get to repair her?

https://www.youtube.com/watch?v=bnvP-6xmql0&feature=youtu.be

It's also taking longer than expected because I just got a new project on the go as well. Thumbs Up Twisted Evil

Hi

Going some to snap a banjo bolt.

The bolts on the reservoir are probably just small counter sunk bolts. Should be easy enough to get some (bigger problem is getting them with a philips head rather than an allen key head).

All the best

Like the new project - that wheelbarrow will clean up just fine Thumbs Up

Are the brake hoses original? Might need replacing to get good firm brakes, but doubt you'll ever get them as good as modern systems. I seem to remember older Kwaks like this generally having a bit of a wooden feel, but should be able to get them so the lever doesn't come back to the bar.

I think the lines are after market, stainless steel braided on the front. I don't when they were fitted but they look in relatively good nick. I don't think I'm doing it wrong, because I did the back brake fine, that feels really good.

I am going to grab some more brake fluid on the way home tonight and give it another shot. I will pull it off.

After brakes, what would you attack next? I still need to clean the carbs properly because it's running quite rich, so I'll do that. What's going on with the rear sprocket, does anyone know?

Feckin hell, that's a lot of movement Laughing

Has it got any cush rubbers in there at all?! The rubbers may shrink/degrade over time.

Also, the sprocket carrier might have a bearing in it - check that too.

Braided lines sometimes take ages to bleed. You pump and pump and pump for what seems like forever, then bang! they suddenly firm up.

Thanks.

There's a paddle and rubber cush-drive in there; Get new rubbers for it; they are only about a tenner ISTR.
The sprocket carrier sits on the axle, and has a bush or bearing in the middle as it goes round with the wheel.. and that would appear baulked. Not sure on the Kwak, it's been 20 years since I looked at one, but may need a new sprocket carrier, if you can get one, if the bush/bearing isn't service replaceable; failing that; take it to a local engine re-conditioners, and ask them to re-bush the old one. They should be able to drill out the old one and shrink in a new bush; take the axle with you for them to measure up if you have to resort to that salvage.

I did up a 550 and found the front brakes to be total poo.
Admittedly someone put the callipers on the wrong sides, I assume in an attempt to bleed them through the banjo bolt as the actual bleed nipples did nothing when I swapped them round.

Bleed nipples cost about 50p to replace and can sometimes solve bleeding problems on old bikes. Snapping one off on the other hand causes a world of pain. It I were to do anything to the brakes on an old bike again I'd replace them.

As for the bleeding, I've always just used a long length of clear pipe. Place one end on the bleed nipple then suck hard on the other end. It works as well as any vacuum bleeder from a shop. Keep going until the fluid is clean and bubble free.

Congratulations. That is a very good bike with a very willing & revvy engine. Surprisingly quick & thrashable for what it is. I loved mine. Don't worry too much about the rattles, they all do that Sir. Eighties Wackysakis were the most reliable noisy engines. They are also liars. My old GT550 would flash up the oil light after a goodly thrashing, never used any & it rattled just as much as the GPz.

The bike is my dads old Raleigh, she found her way home after 20 years, not sure on model, I did look.

I'd heard the brakes were good, seeing as they came off the 750, a bit over-kill at the time. I like the engine, she seems quite responsive while revving her up in neutral.

It will slow down again for a while, like a moron, I put contaminated diesel/petrol in the daily ride, TTR250, so I have been sorting that out instead. I have also just got another new toy, needs a bit of work but mostly ready to go. Twisted Evil Keep an eye out, I'll be showing that off very shortly.

I used wemoto for res caps for my GT550, should be the same.
Or measure the size and check against another bike where you can get them. I've got a stock of them kicking about as I got angry with buying cheap bikes and not being able to bleed and reseal them without a ballache so I just bought 20 odd. I think they were for a CBR600, but they've fitted a TLR, a ER5 and a Blackbird, so it shouldn't be too hard to find.

Today, I had a go at a master cylinder overhaul, to try and stop the brake lever travelling all the way to the handlebars.

Also thought it might be handy as a guide, I couldn't find much on t'internet.

First things first:
https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160200_zps01613fdf.jpg

Began by loosening the screws on the master cylinder and removing the cap.

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160196_zps9b42cfde.jpg

I then sucked all the fluid out the master cylinder before attaching a pipe to the bleed nipple on the nearside front caliper, that's front left to mere mortals.

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160197_zps54b43656.jpg

I removed the lever to reveal the piston

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160199_zps40e9579f.jpg

In order to remove the brake light switch, to get more room into the master cylinder, I had to remove the throttle and the switch gear and slide the brake perch along

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160201_zpsf921e848.jpg

Brake switch out, one mashed phillips screw holding it in place.

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160202_zps29ca64ca.jpg

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160206_zps4345ef34.jpg

I removed a plastic locking tab from the cylinder using two flat-blade screwdrivers to slide it out.

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160203_zps64349442.jpg

I then pulled the first rubber seal out the cylinder.

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160204_zps00b0dadc.jpg

With a bit of a wiggle, and a gentle prising with a flat-blade, the piston can be removed with other seals and spring attached.

The piston looked like it was corroded a bit and the seals were swollen and looked a bit worse for wear on close inspection.

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160205_zps47adc2ab.jpg

New kit looked like this

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160207_zpsab5d011f.jpg

While everything was apart, I cleaned inside the bore of the M/C and reservoir with a clean rag and a bit of brake cleaner. I inspected the bore for any scratching or corrosion.

I installed the new washer provided over the end of the piston, then pushed the new rubber seal over the end, I lubed everything up with new, clean brake fluid and pushed it in.

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160208_zps0d891dfd.jpg

All pushed home, remember to keep the old plastic retaining device, I found this fiddly, trying to keep the rubber seal square inside the master cylinder and locking the plastic clip down so it was square and nothing was trapped.

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160209_zps9d6e7672.jpg

I re-installed the brake switch with a new screw that I happened to have laying around, actually it was a master cylinder screw provided by c_dug, who sent me a few variations of master cylinder screws to replace the mashed reservoir cap screws on my bike, unfortunately, they didn't fit my GPZ but some went on my other bikes and _Iain_ provided the fresh ones for my 550. Thumbs Up So a big thanks to those two!

I re-fitted the lever and filled the reservoir again ready for re-bleeding.

https://i1302.photobucket.com/albums/ag134/Fladdem/Master%20cylinder/PB160210_zps68c2c9bf.jpg

Put everything back together, and just finished bleeding the brakes as the rain came in, well done me!

Seems to have made a good difference, to lever feel, it moves a lot smoother and springs back better as well as not travelling so far.

I also replaced the front brake pads today.

Hopefully more to come soon. Thumbs Up

EDIT : I just remembered, if you do do it like I did there will be brake fluid inside the bore of the cylinder still, so be ready with a rag or something when you pull the piston out so as not to spill it on your nice shiny paintwork.

Today, I decided to find out what was going wrong with the rear sprocket, why it was so loose. Laughing I can see why now...

Getting the wheel out was a right fiddle, you needed to remove the chain guard, brake caliper torque arm and you don't need to, but I found taking the silencers off made it easier, and then wiggle the sprocket carrier off while it was still in the swinging arm, before wiggling the rest of it around the plastic number plate holder monstrosity.

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/PC270239_zps7aca3f8e.jpg

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/PC270240_zps24fab8d8.jpg

Mashed another screw. Embarassed This one on the chain guard,

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/PC270241_zps7ac013ca.jpg

The sprocket carrier bearing, Can you guess what was causing the wobbliness now?

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/PC270242_zps5a2635df.jpg

The cush rubber looked OK,

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/PC270244_zps4343506d.jpg

I'm glad it was the sprocket carrier bearing and not the cush rubber, £11 rather than £45...

The cush drive rubber seems in good nick, it's a bit sloppy on the hub posts, but hardly anything, less than a millimetre. I was wondering if I could pack it out with something? Like with anti-roll-bar bushes, you can take the bushes out and wrap a bit of electrical tape around the bar before putting the bush back on as a temporary bodge for MOT...

Anything a bit more permanent than that for this? Going to order a chain and sprocket kit, new sprocket carrier bearing and then move onto the forks.

I also straightened out the offside pillion peg, somehow it's been bent down and melted onto the exhaust, so I straightened that out to keep it away from the exhaust pipe, if I ever need to carry a passenger, I don't want to have to clean burnt rubber off the bike for ages.

Also going to need to order a front brake lever, like a gorm, getting it off the paddock stand I managed to throw it onto its side and snapped my brake lever. Embarassed Brick Wall

Today, I decided to attack the rear wheel on my Kwak.

First thing, replace the sprocket carrier bearing.

So got the sprocket carrier on the very cluttered bench.

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P1240281_zpsd2xdq4o6.jpg

Sprocket off

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P1240282_zpshvvrdvou.jpg

Worn teeth, change that.

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P1240283_zps4ux4cr8m.jpg

The inner race just fell out, that's all the bearings that were left in there Laughing

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P1240284_zpstw5jn3kr.jpg

Circlip removed, using a centre punch and two flat blade screwdrivers.

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P1240285_zpstr3xgjbd.jpg

Battered the old outer race out with a centre punch, assorted chisels and an old screwdriver. That handy oil can, actually is a mixture of engine oil and petrol, it's wicked, it came out of my dads GS850's sump when his floats got stuck and flooded the engine we have about 6 litres of it. It works so well for loosening stuff, as it's so thin.

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P1240286_zpspcw4tm1f.jpg

A shot of the work bench, complete with H100S engine, a sub woofer, a stereo assorted exhaust pipes and at the very right, the front end of an MTX125 RWD Mr. Green

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P1240287_zpsb4ibfw5q.jpg[/img]

To push the new bearing in, I used the old bearings outer race, as it sits, perfectly on the new bearings outer race Thumbs Up Only problem I had was that the old bearing got pushed into the hub as well. I used a block of wood and tapped it with a hammer.

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P1240288_zpszwjsvzug.jpg

New Sprocket

I followed chris-red's advice, I found an old inner tube and cut little sleeves out of it to sit over the top of each paddle on the rubber.

I replaced the rear wheel bearings as well while I was at it. Look what was inside the hub, some springs all tangled up.... Thinking

That inner tub trick worked a treat, check it!

I wanted to try and replace the rear disc as well, it was advised on the last MOT, before I even looked at the paper work, I thought the disc was suspect, so I bought a new one. Unfortunately, the wrong disc turned up Evil or Very Mad

Old Disc

New Disc

The old disc mounts to the hub with five bolts, the new one that turned up had seven mounting holes. I'll see if I can get a refund, if not see if someone on here wants a cheap rear disc, it will probably fit most other bikes in the GPZ family, just check how the original disc mounts to the bike, if I can't get a refund or a swap.

Tomorrow, I'll have a go at the front sprocket and chain. Thumbs Up

In the end, I had to put the old disc back on, it's not too bad condition but is definitely something to keep an eye on in the future. It's annoying after paying sixty something quid for it, I can't use it. So, it's up for grabs for £50, or a sensible offer, got an advert up in the sale section, but I have no need for it and I can't be bothered to stick it on eBay Laughing

One thing I forgot to document, but back in September I did a mod to the gear lever, the original sat really close to the foot peg, my size 11's were struggling with it, and all the bushes had worn out in the linkage making it really sloppy and horrible. I thought about what to do about it, then remembered that my pit bike came with the original gear lever, my mate replaced it with an anodized one to unleash more power, or something. Laughing

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P2070306_zpsos3lostu.jpg

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P2070307_zpsfkfo68ey.jpg

So I measured up the gear lever, it was 6 inches long, I then got my dad to measure back to just above my big toe, it happened to be 3 inches. SO I got out the angle grinder and removed three inches, chopped off the splined end and then three inches of lever. I then got the welder out and glued the now shortened lever back onto the splined end.

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P2070308_zps1azdmknq.jpg

The original lever however, had a bend in it to miss the sprocket cover/crank case. So to avoid my straight pit-bike lever from gouging a mark into the engine, I cut a small V out of the lever, at the peg end, bent it out a touch and filled it in with weld again.

It works really well, I sprayed it with some VHT paint, but the length of time has let rust start coming through the paint again, obviously too thin a coat. I was worried it would make the gearbox upside down, but it still works the same and is much comfier and no slop! Thumbs Up

https://i1302.photobucket.com/albums/ag134/Fladdem/GPZ%20550/P2070313_zpsr3maeqcy.jpg

I also changed the front sprocket and chain.

Sprocket was easy enough but the circlip holding it on had seized, I worked it loose and eventually managed to wiggle it off with a skinny flat-blade.

The chain was another matter, I bought a chain breaker tool the other day and couldn't wait to use it. I ground the head off a pin of my choice on the old chain, got the tool on it and started to try and push the pin out. The chain tool pin bent and snapped. Useless.

So I just chopped the chain in half with my angle grinder and was done with it.

I measured the new chain up against the old chain to find that the new one was slightly shorter. I hoped that that was just due to chain stretch and that with the wheel pushed further forward, it would fit.

Nope, still about 4-5 Links short Evil or Very Mad

I don't know what to do about that, can you buy links separately to extend the chain a bit? I have some spare links at home, but they're for a 520 chain, this one is a 530, so it won't work, will it?

You haven't told us yet how the wheelbarrow refurb is coming along or are you too tied up messing with this old motorbike ?.

Yep, I've done it again, ordered a chain for a 1982 GPZ550, the year it changed to a Uni-trak rear end, and ordered a bit for a GPZ D1 instead of the H1, they use a 100 link chain and I need a 104 link. Mad

I'll see if they'll swap it for the correct one. If not, I'll either have a spare, for if I fancy trying out a smaller front sprocket, or try to sell it, like my disc. Rolling Eyes

I've just found no time for it. I was thinking about trying to hunt down some OEM handle grips. The front tyre is starting to crack, depending on my usage I may need something slightly stickier compound, I try to push my 'barrows quite fast and I need all the grip I can get. I am half tempted to keep the rat-look and lacquer over the patina, or give it a shock-blast and powdercoated back to original colour, but with faded red/orange pin-stripes to match the grips and wheel.
