Crankcase Heat

[sportandroad]

Is the bike still in Perth. I've repaired two 08 clutches this week. Both overheating to buggery because of the back torque limiter. One continued due to the inner hub not being cleaned and the accumulated crap blocking the oil ports.

Hi Camel

Thank you.

Not it's no longer in Perth unfortunately, I am now in Melbourne. When you say "because of the back torque limiter" can you expand a bit more on that for me?

Are you sure you have more than the usuall heat in that area, any problem with friction involved would become very obvious in the last 5000+ kms since replacing the clutch ,
Tried a IR temp gun , i would think ~120 deg in normal use

Thanks for the reply. The heat is extraordinary, almost to the point where you can only ride the thing with your leg hanging out in the breeze. I rode it once in Karratha for 5 minutes with shorts on and ended up with a burnt right leg. I have not yet mesured the difference with a temp gun.

Sounds like Camel may be onto it.

I now believe it is the other way around, something is heating the oil (when riding only - at idle on the stand no issue) to a point where it damages the clutch.

Definately not an expert by any means but a possible idea
Could it be the clutch isnt getting enough oil therfore causing your heat issue

I had a engine with a burnt a clutch
The burnt fibers had blocked the oil galley that feeds the clutch pack

Thanks for the effort, this may be what Camel is talking about in his reply aslo
