Title: Clutch cover oil drip
Post by: Terrapista on April 14, 2017, 04:07:06 pm: I have tried everything to stop this minimal oil drip. I notice it comes from a bolt location thru the gasket between the clutch case and cover. Is there such a thing where you can infill the thread so the bolt can seal and case, cover and gasket are flush. I have already cleaned and run a blade on case and cover to ensure they are smooth.
Thanks for a leg up on this one.

Don't be tempted to keep tightening the bolt

Also used tiny amount of threebond on gasket so it wouldnt move when placing cover on as i wrecked a new one at this bolt. Will pull apart again to make sure this is not happening again and cause of leak.

Try simply putting a soft copper or soft aluminium washer under the head of the screw first.

I am with you there Paulos,,,,covers are called "Covers" for a reason,,,"Quickly removed whilst engine still in the bike for servicing,,,I totally loathe crap like Z bond on frequent "Non Total Overhaul areas",,,,may as well weld your counter sprocket on ::) ::) ::) ::)

Post by: Terrapista on April 15, 2017, 07:57:27 pm: Yep. I will clean up again and smear gasket with grease. And will place washer on offending bolt. Lesson learnt.
Thanks people.
