The place to come to share your technical expertise, or just find out what the little springy thing is that's just pinged out of sight under the work-bench.
Evening fellas, not as bad as it sounds. It's in bits by choice not catastrophic failure (luckily).
I'm investigating low compression on 1 cylinder so decided take it apart. I need some new rings on 1 pot, using oem for base, and the 2 head gaskets.
I've decided to take all the valves out to check and lap back in before setting the clearances but I suspect I'll have to do the oil stem seals as well. Should I go genuine or will the fleabay ones suffice? Has anyone used them before?
And one final question, is there anything else I should check / change while it in a million bits?
When I did mine last year I played it safe and used all Yam items.
I know you pay through the nose for them but at least you have piece of mind that it's as good as it left the factory.
Just make sure you don't mix the inlet valves up - the middle one is a different length to the two either side of it.
I would also renew the large O-rings at the base of each cylinder (as Banner pointed out).
Good luck!
I was going to replace the seals as a matter of course, just raised the question for the stem seals due to the amount of them. I will probably go with the bay and hope. But if you have had no issues - I'm sure they be fine.
Quick question wrt parts numbers - just been perusing the bay as you do and notice similar gaskets for yzf/fzr/thunderace with the same last digits just with a different number/letter configuration at the beginning? Is this referring to the model and is it the same part? Ie yzf 3fv-11182 THunderace 2gh-11182
Probably a daft question but thought I'd ask anyway.
much better than bottom ends.
