OH FOR FUCKS SAKE

[Visitor Q]

Right, as you may know, i was fitting blueflames to the cbr.

It took me literally only about 90 minutes to get up to the fiddling with exhausts stage.

Then it took another 7 ours to get the ports/mounts to match up and do it all up, during which i came to the realisation god does exist, and he hates me.

Then today, ive put on the radiator, sorted coolant and started it.

And a/the port/s is/are blowing, DEFINATELY one of them (the one it took hours to mate up at all)

And i have two choices, (both involve taking ovver the rad again ).

Choice one - Take the rad off and do all the bolts up extra tight, which i couldnt really do yesterday as they all seemed at the point of snapping basically the whole time i was doing them up.

Choice two - Take the rad and exhaust off, and chuck some gaskets in, which will probably mean the whole thing will need to be set up again, and knowing my luck STILL wont fit. And to be fair, i cant see any space for gaskets in there anyway (although i know you can get gaskets for the cbr manifolds).

Then theres the third and more likely option, im going to go get very stoned and forget about it.

I mean if push comes to shove i can put back on the ridiculously holed original pipes, and stick on the stock can (no way in hell i can be arsed getting the micron off of the blueflames and putting it back on link pipe... too many hours blood and sweat went into changing that).

Im just worried whatever i do is going to end in tears.

I suppose the only safe thing i can do is get some titanium studs, hopefully in better shape, and gaskets, and hope that solves it.

But anyone know for sure? Fitting the exhaust was so hit and miss as to render it all rather unnerving (how far in, how twisted, which way up etc) as to if i have it correct.

My gut feeling is to wander down to the bike place down the road that i ordered some cbr 600 gaskets in for months ago, buy them, and try that. But i REALLY dont want to snap the studs.

Oh and to explain, the engine studs are acting as bolts now, which is one of the many reasons this is hard as hell to do right.

Any thoughts? Tales? Anything... Im open to any advice now, upto a bloody insurance scam at this rate.

gaskets were made for a reason

[Dom_]

You need new gaskets when you fit new headers.

You can't do half a job then moan about it afterwards.

[finpos]

errr...

So the story is you put on a badly fitting aftermarket exhaust without any gaskets, it blows, you are surprised, and you think doing up the fasteners tighter will fix it?

Option 3 for you

finpos.

[BanditsHigh]

Best advice I can give at the moment is to walk away from it and leave it until the next day ... if you don't you'll get more pissed off and either start hitting (expensive) things and/or snapping things.

Go back to it tomorrow with a fresh mind ... any stud which feels as though it's about to snap will ... replace them.

Hope it goes better the second time.

I had problems (quite simple compared to yours ... apart from the new spark plug snapping off in the head) lining up my Zorstec system and Blue Flame cans as well on my GSX1400 ... but I got there eventually.

All the best ... Barry

Deffo need new gaskets mate, there lies your problem.

[Visitor Q]

For all you shouting gaskets at me, in my defence, it didnt have gaskets in with the standard cans, and no one else i know with one has gaskets, and the manifold ports dont actually look like they need them.

Also 3 of the 4 ports seem to have mated fine.

Almost tempted to just wrap copious quantities of gun gum around the hole.

Oh and trust me, changing pipes on the cbr isnt half a job

It equates to /just/ checking sparkplugs on a vfr, ie radiator off, tank off etc.

Absolute fucking pig to work on sometimes

I'd have a closer look at the exhaust ports ... I find it very hard to believe that there'd be no gaskets ... they are probably just flattened/covered in crap!!

Can I join you on option 3

I've never seen any exhaust system that didn't use gaskets. They are usually pretty meaty items that will crush to some extent when you do up the header bolts. Because they are quite big, they take up any mismatch between the engine and pipes (as well as dealing with all the thermal cycling)

Possibly what you have done wrong is to build up the exhaust first and offer it up to the bike. I've always built the downpipes loosely into the collector box, then done up the headers first (that's the only tight tollerence you care about so do them first). Then loosely fitted the backpipe(s) and can(s), only then tighten the clamps between the individual exhaust components, Finally tighten up all the mounts to the bike.

As mentioned - do it another day.

I've done the gun gum thing - it's fine until you realise you are skinting yourself buying a new tin every time you fill up with petrol!

Open three, whilst fitting some gaskets.

The header pipes shouldn't need doing up tight enough for the studs to be near breaking.

[Visitor Q]

[EuropeanNC30R...]

Listen to BanditsHigh, the original ones are probably in there, only crushed and dirty.

iirc they're copper crush gaskets, that compress as you bolt the pipes on to ensure the seal.

I'd have thought most bike shops would have the popular sizes in stock.

[Visitor Q]

[Tarmacsurfer]

You can walk into pretty much any spares centre and buy crush gaskets for ~£2 each. Given that the last bikes I've bought them for (all over the counter, walk in walk out) have been a 'blade, a zzr-250, a zzr-11c and a GPz750 I find it hard to believe that having something as common as a CBR600 makes it difficult to source them. When you removed the old exhaust there *will* have been a crush gasket in there, it probably looked like a ring of grime though, they really are not reusable parts. Given the fact that you claim to ride hard, having an exhaust that's blowing will not help engine longevity. Now you've done the job once it should be a damn sight quicker this time anyway

Should be able to get your gaskets within 24 hours (might be shut now though unfortunately).

Have you tried contacting Blueflame with the fitment issues? They were very helpful when I had problems with my RVF can.

Best to take a break from it for the time being.

[Jack_Cheese]

Gaskets this, gaskets that - utter poppycock! Some milliput should sort it!

To test if it is blowing, i recommend turning off your fuel tap, and running the engine 'till it don't run any more. Remove the air filter and replace with gauze. Remove the spark plug and fill hole. PLace copious ammounts of MJ on the gauze, and place a length of hose pipe over the end of the can. Hit the starter, shove the hose in your gob and get a blow torch on the air box.

I would really recommend fitting some new studs if I were you.

Whip out the old ones, flush the hole with some degreaser and loctite the new studs in place. They will cost next to nothing from any shop that does that sort of stuff. My local breaker cut some up for me for about £2 from a lenth of threaded steel.

Good luck, oh and could you send some 'number 3' over to me please?

'Oh, for fucks sake' just fit the new gaskets and studs, and take it as a lesson learned. When fitting different pipes you should always fit new gaskets, and once fitted you don't have to tighten the bolts until they're nearly breaking, the gaskets are designed to crush into shape with the new pipe.

A good lesson for everyone here, trying to save a few quid isn't always the right thing to do.

Ok, im going for aluminium.

They also do engine studs, just i dont know what size the CBR 600 takes, its a 1996 FT.

Im checking google, ive foned wemoto, cant seem to get any info annoyingly.

This is the sizes available. Just wondering if anyone knows which one fits my bike.

Exhaust Stud M6 x 35mm :
Exhaust Stud M6 x 45mm :
Exhaust Stud M6 x 55mm :
Exhaust Stud M8 x 35mm :
Exhaust Stud M8 x 45mm :
Exhaust Stud M8 x 55mm

Hi

My guess is that when you took the original exhaust off, one of the gaskets came out and the other 3 stayed in place.

With the studs, suspect they are M6, but that should be easy to see (and if you used a 10mm socket to do up the nuts on the exhaust then 99% likely to be M6). Length wise not sure, but it is easier to cut down one that is too long, and there is a fair chance that there is space for one that is 10mm too long anyway.

All the best
