Griso 8v 2009 gear shift problem.

Technical All CARC models

Just an update. Whilst the obstruction to the gear linkage was a big improvement to up shifting I decided to flush the old fluid out. To my shame it was black with bits of gunk floating about. So out with the old and in with the new. Much better.

A month later being in the mood for more clutch lever faffing I decided to remove the clutch lever simply to lube it. Low and behold the plunger was loose…the little grub screw that held it in place wasn’t tightened enough. With all my faffing about in getting a setting that was perfect to me the master cylinder piston started to weep fluid. What a job finding a replacement but found one on Wemoto. Successfully fitted it yesterday. Road tested it today and yes all good.

However cos I can’t leave stuff alone I damaged the micro switch so ordered a new replacement….£52 quid from eBay…original stock £135 so I’m telling myself that I’ve saved a few quid :joy:.

The clutch fluid on GRiSO goes black very fast. I was pretty certain that it’s because that master cylinder has a rubber gasket without corrugated bellows. So as the fluid goes down the gasket can’t expand down like on most bikes, instead it gets sucked in and then moisture can get in and contaminate the fluid

Yes I think you are right. I put some Brembo “rubber” grease on the seals so don’t know if that would help….possibly only short term :rofl:
