elk Posted June 4, 2015 Report Share Posted June 4, 2015 Have just bought a 2014 Racing 250 which hasn't had much use, rather nice in fact. However, the clutch action isn't as good as other Gassers I've tried - it's a bit heavy and not so smooth in takeup so I have pulled it apart. The pack thickness is 9.8mm and the lever height is 15.2mm So, how much do I have to reduce the pack by to get the desired 17 - 18 lever height? Or should I just get new plate set?

lineaway Posted June 4, 2015 Report Share Posted June 4, 2015 I`ve never sanded the friction plates as I have plenty of the steel. I would give them all a light quick sand and re-install. Measure the finger height during installation. And if you are still too low. Just run the bike awhile, then find a nice tree or something solid. Click it up to third or fourth and burn the plates in a little. It might take a few tries. Quote Link to comment Share on other sites More sharing options...
elk Posted June 5, 2015 Author Report Share Posted June 5, 2015 Thanks for that lineaway. Sanded the plates to give me 18mm - light and progressive now. Really surprised that these clutches are so sensitive to such small changes in pack thickness. Quote Link to comment Share on other sites More sharing options...
hgas Posted June 6, 2015 Report Share Posted June 6, 2015 My clutch was starting to drag when hot so I put a new dp clutch pack in , the thickness was 9.8 it's solved the drag but now it slips terribly when it's hot , worse in the higher gears, you guys have any ideas where I've gone wrong?

crazybond700 Posted June 8, 2015 Report Share Posted June 8, 2015 Always first check free play in the master cilinder. Do you use the correct oil? Quote Link to comment Share on other sites More sharing options...
