hoodie2 Posted April 23, 2011 Report Share Posted April 23, 2011 I've been checking out threads on clutch improvements having just got a very stock 06 4rt. I've stuck the larger master cylinder on and the clutch is more progressive, but I still find the bike still carries too much momentum with the clutch disengaged. I think ther'es still enough friction for a little drive to be left and I have to kill it with the brakes. Would the dimpled steel clutch plates help this? I can't find anyone selling the Jitsie ones but have seen Apico ones. Are they any good or am I better looking for Jitsie ones, in which case any ideas who has them? Cheers.

munch Posted April 23, 2011 Report Share Posted April 23, 2011 the apico ones are not dimpled. they are pressed to make them flat. the std steels are perfect . the oil and linings are the key. Quote Link to comment Share on other sites More sharing options...

eddyp Posted April 23, 2011 Report Share Posted April 23, 2011 BVM say the following: Apico Clutch Steel Plates Montesa 315/4RT Apico These aftermarket plates actually offer better performance, they are covered in tiny dimples that allow more oil to get between the place. This gives the clutch a much more progressive less switch like action Quote Link to comment Share on other sites More sharing options...
hoodie2 Posted April 23, 2011 Author Report Share Posted April 23, 2011 (edited) That's what I thought. Just wondering if anyone's tried them and found a difference or if they are just as effective as the Jitsie ones.I've changed to a 9 tooth gearbox sprocket already.

bikepilot Posted April 25, 2011 Report Share Posted April 25, 2011 I haven't tried them, but yesterday as a test I removed two clutch springs (opposite eachother) and rode around the yard. It made the engagement just a bit less abrupt and of course the clutch lever effort is reduced. I gave full throttle on a concrete slab and did not detect any slippage, but it was just a quick run around my hard/driveway. Quote Link to comment Share on other sites More sharing options...
