Just finishing off my hydralic clutch on the busa fitted with barnett uprated springs. The problem is when i press the clutch pedal the clutch does not move at all, this is with the cover off. I believe the barnett springs are coil bound and will not compress anymore. If i loosen them off i can get the clutch to work perfectly. Question is, when fitting uprated springs do i need to remove the spacers in the pressure plate aswell as the original springs?

Just a quickie... what master cylinder did you use? as you know I am plumbing in a 2001 busa soon so all help appreciated!

Sounds like it - I'm not aware of Busas having any spacers as standard. Did you have any trouble getting the bolts in? I've got some seriously heavy duty springs in mine from BigCC and you have to actually compress them a bit to get the bolts in which you don't with standard springs.

The master cylinder is this one (link at the bottom). I'm using the standard busa slave cylinder spaced away from the block a bit with an extended pushrod. This isn't the finished article as the plate flexes too much so i've remade it in 12mm thick ally.















The springs took quite a bit of compressing to get them in and as you can see are longer than the standard ones.

Just spoke to holeshot and apparently there shouldn't be any spacers in the pressure plate. Looks like someone has put them in to beef up the original springs.

Hi Busa definatly dont have spacers below the springs its a cheep upgrade but usually works so remove them if fitting the stronger spring
also make sure the clutch outer is located correctly by hand first before fitting springs it should be tight up against the last friction before you fit springs cheers Malc
