it was acting up overreving then going down to like 7700 rpm,s I had to nove the clicker to #2 it was better but still wasn't right , so I am thinking the wear spots in the ramps where causing this,, am I thinking right?

thanks again

Yes, you're thinking right. Replace ramps, rollers, & spring if you still want to keep that clutch.

I think I will put new ramps and rollers in and try to get another 3000 miles out of it ,,,I don't think the spring would be bad

I guess I would need some major convincing to change the primary spring it looks perfectly good to me

Spring lose there rate from being compressed for a long period of time some say 20-30 lb per year

So say you had a 200lb final rate spring after / years of being in the clutch it could be 140lb rate

Which could cause a rpm issue

Like andrew said they sac. Springs imo for proper performance should be a seasonal change.

I personally think changing the spring is unnecessary, but I had mine rebuilt at 4000 miles. It blew an arm at 7000, leaving me stranded.

At least you know what you have now. Most of us don't have the luxury of having availability to test them and if suffering performance then the spring is a good cheap place to start, of course after checking ramps etc.

Measure the free length. If it is close to 4.3 inches you do not need to change it or since you bought a new one you may have a good spare.

Always good to check the spring. Put mine away after my first year running well and when I got it out the next it wouldn't pull the same rpm's, went thru everything. The free length was right on but when I put it on the scale the end force was 30#'s off, new one went in and rpm's were bang on again.

They're cheap performance.......

x2. I do not consider free length a good measure of the health of a clutch spring. Tells nothing of the actual force under compression after the metal has fatigued, and Grovers example is more typical. Only a spring tester can tell spring condition for certain, and those are valuable tools but pretty expensive, and most don't own one.
