senf2 Posted December 30, 2010 Report Share Posted December 30, 2010 i just bought a cota 4rt 05. The clutch is like on/off. Someone told me to install the bigger AJP Master/Cylinder. But my intention ist that this makes it much worse. (Bigger Cylinder = More liquid). Or i am wrong? Quote Link to comment Share on other sites More sharing options...

thesolidman1 Posted December 31, 2010 Report Share Posted December 31, 2010 Hi, another route to consider is replacing only the steel clutch plates with the dimpled ones from Jitsie. Cheaper than the Mitani route. It worked for me to point where I didn't feel I needed to change anything else. "The Jitsie steel clutch plates have a special design similar to the look of a golf ball. This improves the oil flow between the clutch plates, hence making the clutch a lot more progressive and easier to control. An absolute must have for the Montesa 4RT owners." Best regards!

For your information, Before you start ranting, My dad used to own a 05 4RT a few years ago & the clutch was a bit on/off & the Mitani clutch plates definatly helped, The larger master cylinder also did.

Only the reservoir is larger, the bore is the same. The functional difference is the geometry of the lever. Quote Link to comment Share on other sites More sharing options...
senf2 Posted January 13, 2011 Author Report Share Posted January 13, 2011 I just bought the jitsie steel-plates. But a friend has a Beta rev3 2003 Master-Cylinder. Looks like the 315. Any experience with that? Quote Link to comment Share on other sites More sharing options...

Looks like the 315. Any experience with that? I think they're the same. If it takes a different lever than your 4rt it should be good.
