Re: Tweaking a G80...
I have been doing some reading on other forums etc on these mods and some quarters believe that they cause the big end to give out. I would be grateful if someone can shed some knowledgeable light on this specific aspect.
Thanks
Thanks

Re: Tweaking a G80...
What do you mean "give out" ? As in bearing failure? Crank failure? etc?
Fix it until it's broken!
Otherwise how will
anything get done?

Re: Tweaking a G80...
Hm.. I could see that, especially on the drive side. ball bearings I don't think are the best choice for such an application, rollers would have been a lot better. I just pulled the set of RLS8's out of the drive side of mine and with only 4400 miles on the bike, the bearings were already showing a lot more wear then they should have.

Re: Tweaking a G80...
Shouldn't think that there is much to worry about. The C variant competition engine uses pretty much the same bottom end and that seems to cope with the extra 'umph'

Re: Tweaking a G80...
Not to derail this topic, but is there a thread documenting the differences between the C engines and the regular S engines?

Re: Tweaking a G80...
All the comp engines use a roller bearing on the inside on the drive shaft.

Re: Tweaking a G80...
Is this on both sides or just the drive side?

Re: Tweaking a G80...
If you have abog standard G80 then the timming side will be a bush. There are two bearings on the drive shaft the roller replaces the inner one up against the
fly wheel.
