Hi guys, having a slippery problem with my clutch since replacing the friction plates and springs on my H1. When i took off the cover first of all, it was a complete mess! steels stacked and washers on the springs =/. So i removed all plates and put the new frictions in, alternating between steels and frictions, starting with friction and ending with friction on the off-set tang (soaked these in oil overnight). I also found i had to use one old friction to fill the clutch basket . This meant i now have 7 frictions and 6 steels (Is this the correct amount?) i then put the springs back on with just the original washers and torqued them up...only problem is, she now slips
I have replaced the oil with 10w/40 motorcycle oil with a new filter, as it was overdue and found this could be the cause, but still she slips.
Steel plates are not warped and measure on the vernier at 1.6 mm, which upon research, appear to be the steel plates from the J1 model if im correct? All springs are brand new EBC heavy duty and are well within tolerance.
Just double checking if i need to replace the steels for the 2.3mm ones in order to cure cure the problem?
Also i have a mate with a spare clutch assembly from an L9, will the basket from the L fit my bike? and are the steels the same on the L as the H?

Many Thanks
Vinnie

Don't know whether she has the J clutch as it would appear that's where these steels came from. Just a bit stuck on what to do at the moment, any help would be appreciated

Have you used fully synthetic oil? if so that can cause clutch slip.

Nope used semi

if your steels are 1.6mm each, then 5x1.6 = 8mm, your steels should be 2.3mm, so 5x2.3=11.5mm; 11.5mm - 8mm is the amount you are missing from your stack height which is 3.5mm, and with 1 friction plate being ~2.9mm this is why you are needing the extra friction plate to get close to a proper stack height, get brand new proper steels (they are cheap enough from cradley's) and reassemble everything, torque the springs (i think its fairly low, 12Nm off the top of my head) and see if its better now...it should be

I see what your saying by I've had to use a sixth steel also to account for the extra thickness. I calculated the unsprung stack height for 6x1.6+7x2.9 being +1mm more than the 5x2.3+6x2.9? So wouldn't that have the opposite effect?

Late reply,
got the proper plates... all back together works a treat

Cheers
