Drilling the clutch basket always work?

Does drilling holes in the clutch basket always cure the coffee grinder clutch problem?

Always? Mmm, out of the two whole owners that I remember doing it as the sample group......I'd have to say Yes.

I want to end up doing the mod, since it was done at Kawa as a fix anyways, but I am rarely affected by it. If I hear the noise, then it means I failed to let my bike warm up to proper operating temperature. :P

Related question: Does this just solve the noise or does it also help the grabbiness of the clutch?

The "grabbiness" is what causes the noise.... So yes, it does both.

Thanks for the info, everyone. And thanks for the re-post of the diagram, Chris. I want to do it, but can't do it on my own. I've never messed with a clutch before.

I've always used Rotella 5w40 synthetic oil... and have never had a problem. The synthetic is a little thinner at room temperature, so it's already kind of 'warmed up'.

That ^ is interesting. I was wondering why more folks didn't use 5-40 as it would seem to make sense given the clutch problem. Too bad I just changed my oil (10-40 synthetic).

Well not everyone using 5-40 reports the same thing. Why don't you ask n2 if he has no problems with clutch grab on his bike when it's 34 degrees out?

It is true certain motor oils have worked well to nullify the coffee grinder symptom for some owners..... But not all.
