markjw Posted July 27, 2011 Report Share Posted July 27, 2011 Hi I need help, I have a new 2011 SSDT 250 and want to make the clutch pull lighter. I know that it is light now, but I have a very bad left hand (years of injuries take their toll). I have heard that you can either take out 2 springs or put washers in. Can someone please help me with this Quote Link to comment Share on other sites More sharing options...
paullagrand Posted July 27, 2011 Report Share Posted July 27, 2011 You can take the clutch cover off and take out three (every other) or two (opposite each other) of the springs and their washers and bolts. I did this for my son's 1.25 when he was younger and I rode it every now and then and had no slippage. Much easier to pull the lever.

copemech Posted July 27, 2011 Report Share Posted July 27, 2011 (edited) I have run a light clutch on my 2.9 for couple years now. It works pretty well for amature use. If you just pull 2 springs(33%lighter) you will likely encounter a bit odd progression and slippage when engaging higher gears. Thus the need to go to a thinner gear oil like ATF, similar to some other makes such as Beta or GG. The Dan Williams clutch mods as pinned in the Beta threads also help. To add to that, I also put a small needlefile diagonal cut into each pad on every friction disc. I run a high quality synthetic ATF such as Mercedes or Royal Purple, have not tried plain Dextron, yet should still work fine. Member(Chewy) in the UK matched up some lighter springs for his bike, but the(engineering) numbers I ran on them basically gave same effect. You might inquire to him, as he has been running them. I still get decent feel and progression, and can achieve "full pop" when needed, out of my setup, so sticking with it for now. Just a lighter trigger! ps-Plates never stick after sitting, either! At least thus far, but never trust them! Edited July 27, 2011 by copemech Quote Link to comment Share on other sites More sharing options...

Comes down to the much greater torque supplied! Quote Link to comment Share on other sites More sharing options...
markjw Posted July 28, 2011 Author Report Share Posted July 28, 2011 Thank you Will try the lighter oil (ATF) Regards Mark Quote Link to comment Share on other sites More sharing options...
markjw Posted August 10, 2011 Author Report Share Posted August 10, 2011 I put Nulon -full synthetic ATF in and noticed a difference almost straight away. Clutch seemed a bit lighter We have a trial on Sunday so will see. I noticed also the the bike started easier and idled better - although the engine rattled a bit more for a short while Thank you Quote Link to comment Share on other sites More sharing options...
