garydwall Posted April 13, 2023 Report Share Posted April 13, 2023 Hello, I have my clutch pack at 9.74 mm for a 2009 Pro. From what I read the tolerance is 9.75 to 9.85. My finger height however is at 10.50 I find the clutch slips in 5th and 6th gear. The steel plates I have fitted are 1.5mm and 1.6 mm. What do people suggest, I don't want to make the clutch too heavy but obviously need to stop it slipping. The finger height seems to be quite out of range.... Thanks in advance.

Strutty Posted April 13, 2023 Report Share Posted April 13, 2023 if the pack is ok condition, id probably put a thicker steel plate/(s) in to pack the thickness out if the packs below thickness its never going to be brilliant, alternatively could run a thicker spring ring, but this will make the clutch heavier. Ive found finger height to be more important on a gasser than the pack thickness but everyone has their own experiences 1 Quote Link to comment Share on other sites More sharing options...
garydwall Posted April 13, 2023 Author Report Share Posted April 13, 2023 Thank you. What is the recommended finger height? Quote Link to comment Share on other sites More sharing options...
lineaway Posted April 14, 2023 Report Share Posted April 14, 2023 I believe it was 17 mm. It needs to be thinner to get that height. The easiest way is to get the bike warmed up, stick it in fourth gear against a wall and give the clutch hell. Otherwise there is a few videos to show how to do it by hand. When the pro first came out you could get as small as a 1.3. I save all I come across, must have enough to be a deck of cards. Quote Link to comment Share on other sites More sharing options...
garydwall Posted April 14, 2023 Author Report Share Posted April 14, 2023 Thank you lineaway, I'm a bit confused, if my clutch is slipping now, will burning it not make it worse? Would I not be better increasing the pack thickness? Thank you Quote Link to comment Share on other sites More sharing options...
lineaway Posted April 15, 2023 Report Share Posted April 15, 2023 The Pro clutch can be a little hard to get right. The original spring might be needed. The finger height has to be right or the pull is very hard. Good luck. 1 Quote Link to comment Share on other sites More sharing options...
