Bought some new 2000rpm clutch springs to hopefully to fix my idle throttle clutch movement issues. After going at some speed with the bike the engine takes a while to lose enough revs down to the point where the clutch is no longer engaging and spinning rear wheel. I dont really want to turn my idle speed screw down any further so I'm thinking new tighter springs will help the situation, hope everyone can understand what I'm saying here and also how hard are the springs to replace? Thanks

That's too bad there was no difference... I was going to do the same thing.
Hey Hypojam, do you think there would be any perfomance value in modifying the large spring in your second picture? I think putting in a weaker spring (or cutting it down) might make it go faster, bacause it would be in a higher gear.

This is what Cantlogin Wrote about it:
"The spring in the rear driven pulley only controls the gearing by varying the position the belt sits, in the pulley. A stronger spring would make the belt sit higher, giving a lower ratio (slower speed/higher engine revs), whereas a weaker spring will give a higher ratio (faster speed/lower engine revs). The real issue, which would warrant changing the gearing ratio, is whether the bike has low enough gearing to climb the steepest hill you need, and is not revving it's nuts off downhill at the other extreme, taking the power it has available into consideration.
The balance on mine is about perfect, as it has a low enough ratio to climb uphill, but still flies downhill without over-revving. My advice would be to leave well alone. "

Hahaha, I measured mine and it was not 36mm. Mine was about 40mm. I tried grinding it down with a dremel and got it to 39.85mm in about 20minutes of grinding so I gave up.
Maybe this piece is why yours goes faster!
