i just had new bushings pressed in at the dealer, and am in the middle of tuning the primary. i took the primary cover off to change springs and noticed how hard the sheaves were to slide. i actually had to push down on the movable sheave to get it to close-- and it definitely wasn't like that before. i'm no clutch tuner either, so i figured i'd ask-- is it normal for brand new bushings to be tight like that?? thanks for any help
not unless they got a tiny edge on the bushing when they pressed it in, best thing to do is very lightly take some wet/dry 600 grit paper and go over the bushings. You want no drag here, if it drags when you move it by hand, when the sleds running,hotclutch's and with alot greater force is gonna rob you of alot of power. Smooth them out till they dont drag, you can lightly buff the metal parts as well

What year, model is the clutch off of? Did they change the spider bushings also? If so, pull the end cover off and see if it slides freely, while holding the movable sheave centered. If it binds, bolt the cover back on with no spring, and retest it for binding. If there is still binding, go ahead and reassemble the clutch, and take it for short ride. When you get back, pull the spring out, bolt the cover back on and retest it for binding by hand. If it's still binding, then the clutch will need to come apart to see where the bind is. If it's the spider bushing's, some light sanding of the bushings may be needed to gain the proper clearances.

thanks for the replies guys-- ya they put in a new spider bushing- the metal one, they didn't put the plastic spider bushings in (the ones on the ends of the spider arms), and they put a new nylon cover bushing in- which they damaged trying to put in a gray HC spring- they ordered me a new one. but the funny thing about that is they never told me- or maybe they didn't realize they did it. anyways, the cover bushing is not binding. it binds with the cover off, so it must be the spider bushing. i did take it for a short ride, so i'm gonna go pop it back off and check it again right now. and i'll check it with no spring and the cover bolted on. i'll get back to ya

no luck-- she's still binding-- the one on the moveable sheave. do you guys know of any other way to get the spider off without the removal tool?? i'm gonna try lightly sanding that bushing. thanks
Also-- that is a left handed thread?? so you would turn the spider clockwise?

yes, its left handed thread, you can make a tool yourself. take it apart and sand lightly, sand the stationary sheave base as well to make sure it doesnt have any burrs on it.

thanks mrviper-- i got it apart and it appears to have a teflon coating on the bushing-- where the coating had already started to rub off, it's pretty rough- the more i sand it, the more the black coating comes off and it looks like copper under it. have i wrecked it? or should i keep going till it slides smooth??

well i think i may have found some of the problem-- one of the plastic bushings on the spider arms looked like it had a small gouge in it from a piece of sand or something and the aluminum pocket that it slides in was also scratched, so i sanded them down smooth. it slides a lot better now.... thanks for the help!
