What have you done to your bike today?

[trevor saxe-coburg-gotha]

in a bid to get rid of a bit of pulsing on the front brake lever of my zx9r c2 i set about freeing up the bobbins as i suspected for a while that the discs aren't "floating" any more

i got a nut and bolt of suitable size, a gloss sized paint brush and half a pint of isopropyl and got on with cleaning and freeing up the seized bobbins - there are seven per disc

some were pretty tight tbf

once done, i got on for a quick ride to see if there was any difference - at first the feel on the lever was horrendous - but a few stops later and things had improved considerably, and 3 miles later the feel on the lever was sweet AF (gone was the wooden lack of feel and the slight pulsing sensation). Lever travel has always been amazing on these callipers - it's barely half an inch or more

these are refurb'd Nissin 4 pots of a bandit 12, which i replaced the oem 6 pot tokicos with about 18 months ago - bolts straight on...huge improvement imo, esp. with braided lines

Rear sprocket change (new chain was fitted about a week ago). Upon removal, discovered that the old sprocket was a hilarious "JT" fake. Wonky lettering, etc.

[blurredman]

Layed new (temporary test wire) from ignition switch to coil + to eliminate a few enquiries on the Trophy.

Funny, just tested the coil + feed on the old KZ1000 (getting >12V so that seems okay) but tried starting it with the plugs out and one coil pack - outer cylinders - doesn't seem to generate sparks till the engine's been turned over for a bit (compared to the inner cylinders which have a good spark immediately.) >40yo coils so probably worth replacing.

Hopefully replacing 'em sorts the rough idle problem.

Changed the rad cap on one of the Deauvilles as it was making an odd sucking/blowing/whistling noise. There was crystallised coolant around the cap seat so guessing this was the problem, time will tell.

Bit of a nightmare to change as per a lot of modern bikes, the cap is covered with bodywork so 2 hours work to change it.

Finally settled on a luggage solution that satisfies me. These high quality bags have enough space in them for a picnic.

The ammo tin was the coolest-looking storage method I tried. However, it was only big enough for use as a tool case. Plus the steel began to bend and the tin drooped after a while. The on-seat My Little Pony thing from Ebay had plenty of space, but the cheap nylon straps chafed and wore through.

I think it's going to be these bags now, and that's it. I've bolted a little bit of square-section steel behind each bag to prevent them reaching the wheel. However, I'll need to improve those, as they're sharp and pointy at their extremities, and will eventually damage these bags. Currently attached with zip ties, although that will change (to paracord).

Update: these should do.

110% success by replacing the KZ1000 coils!

Recap: bike was a bit rough on idle even after warming up. Basically got to the point it'd stall under 2000rpm Tried carb clean and then found we weren't getting a good spark on the outer plugs. New coils + all new connectors and now the bike's running better than ever! Almost starts and runs with no choke (with the current clement weather.) The old fella's well happy

On the Triumph we were going to have a latching button for the hi/lo beam but the new one that's turned up is the wrong thread size. Fuck it, gonna stick with the current momentary button and back it up with a latching relay. The hi/lo beam will then work much the same as the "Harley-style" indicators.

Spent most of the weekend working on the ‘03 R1 and I enjoyed it but ultimately I haven’t been able to diagnose the stalling which prevented me getting to the MOT on Saturday. Disappointed in myself. It looks like I’ll have to ask the local bike shop to bring the van of shame and collect it for repair.

[redeem ouzzer]

Jumped on the GK73A project bike over the weekend.

Picked up a set of powder coated metalwork for the back end last weekend (rear subframe and exhaust brackets). Got it all on and bolted up, had to make a plate to mount the rectifier using a real one as a pattern.

https://live.staticflickr.com/65535/52045766179_8484a15566_b.jpg

Fitted battery box and sorted out all the wiring in that area, then realised at some point a previous dickhead has routed the wiring harness the wrong way (should go outside the frame and clip to the airbox).

https://live.staticflickr.com/65535/52044473092_96288fabf7_b.jpg

Disconnected the loom from the front and pulled it back through the frame spar, i'll sort the routing out once the new grommets come.

Used the unwiring as an excuse to remove the rather tatty clocks and build a decent set with an MPH speedo off an RGV with new sponge and backplate. Much tidier.

https://live.staticflickr.com/65535/52045766109_65896ccfdc_b.jpg

Removed the GSX400F forks which it came with and fitted a reasonable set of standard forks (new seals and oil).

https://live.staticflickr.com/65535/52045767759_690953d838_b.jpg

Realised the battery it came with was as Li-Po so that will be going in the bin. I have no way of charging such a device and I don't trust the charging system on the bike to cope with it.

Carbs are away being done so I aim to get the cooling system, exhaust and wiring back on before they come back. At the same time I should received some spare wheels shod with new tyres. The risk with the project is I have no idea how good the engine is. I did the clearances last weekend and there were a few pitted cam lobes (usually a sign of crap oil or infrequent changes), but it looked clean and had good draw on all pots. Worse case scenario I freshen up one of my spare engines and chuck it in over winter.

Does sound like strangely similar symptoms especially the "keeping above 2000 rpm"

FWIW we tested the coil resistances (cold) and they were all within spec. With regards to replacing them you just need something that a) fits and b) has similar primary and secondary resistances, the expected voltage is largely irrelevant. (Condensers/capacitors do have a maximum working voltage so be careful there.)

If it's similarly wired as our T140 then the lucas coils get a 12V feed (check if it's less - hints at poor wiring or corroded connectors) and the points would switch to ground when spark is required. I mention this as you might want to turn over the engine by hand and see what the resistance is between the coil negative and frame.

On ignition coils, I will say, stick to the OEM/manufacturer's parts. I've had my share of ignition coil troubles where I've tried to go cheap, in the past. Just isn't worth it. On a 40 year old Kawasaki, I would rather go for a 40 year old Kawasaki original ignition coil, than a Chinese surrogate. If good 40 year old coils are unavailable, I'd switch to a complete replacement electronic ignition system, e.g. Dyna S (there are a couple of other companies that do them, too). As for the points and condenser - replace them anyway as a set because they cost peanuts and it's a no-brainer. Stress-inducing misfires happen when the points are on the way out because of a bad condenser, and it's hard to see pitting or burning on the points, so just replace them if in the slightest doubt. I know you know guys know about electrical stuff and I'm not trying to teach you to suck eggs. That's all I've got to say.

[blurredman]

Yep, I got to work yesterday despite the misfiring, but barely got home. Indeed a few times complete engine stop (whilst riding). Which are symptoms of coil that weren't there before in the same way a mere few days ago.

Either way, as soon as I got home did coil resistence checks (perfect, and not physically hot) I swapped condensers between the bike and another one to rule them out. The Trophy was exactly the same. Misfire, splutter, backfire. The other bike with the suspected condeser was fine- I later used that to go to the shops to test, but also came to work on it to-day and it was perfectly fine... So not condenser.

So now I have to find a nice miniature tube type 6v coil.

I was hoping it would be the condenser, as I have those spare, I also have a few 12v coils spare- but no 6v. So I have to actually spend money on this one..

I dunno really, because when you think about it 6v was used until relatively recently esspecially on small Jap bikes..

This bike manufacture date is 1972 so still a period of time when either system is perfectly acceptable to the populous. 6v totally DC system. But isn't Japanese, German.

Anyway, got a coil lined up to be picked up on the next club meet on Sunday.. Woop woop.

You can get these things quite cheaply, and I am one to buy cheaply and twice. But, in this case it's handy having the same dimension coil for standard fitting as opposed to getting creative.

Finally sorted an intermittent electrical issue on the ignition sub loom on the M750 and fitted a pair of high output coils to improve starting.

Replacement timing belts on order and once they're fitted and it's MOTd, it'll be good to go for the summer

[to v or not to v]

started the thing up for the first time since October and gave it its annual wash. all seems well
need to book it in for an MOT now.

its old and fat, but its a damned good ride. the bikes not bad either.

[ThunderGuts]

What started as a pre-MOT check session on the C90 ended up with a tube of Autosol and some gentle rubbing.

Never seem to get round to my stuff so today after and putting up another 14 ft long book shelf in our spare room (that makes 11) for my wife.
I went out to the local dirt bike shop to look at the Sunday motors flat trackers.
I was half thinking of getting one to improve my skills and not risk my road bike, but I don't know where I could use it, so just got a flyer.
I'm 60 and the practice track time is organised buy age groups because it's aimed at kids.
Once home put my sv650 lithium battery on charge and removed my volt meter and wiring and lowered the clip on bars 1" on the forks.
Both these changes are to make clearance for the 1/2 fairing I am currently mounting but the weathers too sh*t to do much else.

[Easy-X]

Working out the wiring on the ol' Triumph, headlight bucket's the usual rat's nest:

And the handlebar switches:

Just in loosely for now until I've fully tested everything.
