hd clutch springs

Ok. I just installed a 4 mill stroker and now my clutch slips. It has a completely new clutch(minus the pressure plate). I found some springs on rockymountainatv.com that I am about to buy. The thing is they are only 10% stiffer than stock. Is this how stiff most hd springs are? I figured they would be alot stiffer. Also, you think i will need to run just 3 or all 6?

Anybody? Also, my tranny seems to make a bit of noise. I don't remember if it made this much noise before or not. It sat for like 5 months during my stroker re-build. Are banshees noisy in the tranny? it's not a grinding or anything, i just can hear the gears spinning.

you should be able to run 3 of those springs and be fine.

 

The noise you are hearing is probly the plates. not the gears. If the gears have enough play to chatter they will break, the plates viberate and make noise commoly when you get a new basket and inner hub.

Remove the clutch fibers and steels. Look for a glaze on the fibers, look for blueing on the steels. Measure the thickness of the fibers (measure the block pads) and the thickness of the steels.

 

A healthy dune ported stock cylinder 4 mil could use at least 3HD/3 stock springs. Buy a nice new clutch cable and an EZ pull lever/perch, and use all 6 HD springs.

I have searched this very subject. It's not clear in the manual. We all know what the fibers look like. Is the proper way to measure to put the caliper in the groove on one side and on top of the block on the other side? I hope I explained that right.
