im working on dudes stock magnum 425.....i havent taken off the cvt cover yet but have already decided to replace the belt and springs....it rattles bad at idle...and goes away when you rev up to approx 1500prpm .... are there any suggestions on whatelse to replace while in there....the guy mostly trail rides and some mud bogging(even though 2x4)....thanks in advance!

Take the front clutch off and get to buttons replaced.

 

would you go with just stock parts....or can you get aftermarket for less,more,better....thanks for your reply

 

Go with stock parts but if you want to hop it up a little put in a white polaris primary spring(400 Scrambler spring) use stock weights and if you want to mod the secondary I am partial to the Aaen blue secondary set at 2-2. That is what I ran in my old 425 and it worked great.

 

I wouldnt fool with the springs and such, since its an older bike it has the old style clutch cover look and make sure that it is not rubbing in the clutchs couse most on the time they rub at idle but slightly above idle they wont

 

When you get the cover off you can tell if the clutch has been hiting it.

 

hmm....i thought all the rattle was loose springs....i wont be able to start til this weekend..are there any special tools needed for this job...thanks again

oh yeah....i had a 98 sportsman(stolen:frown[img]i/expressions/face-icon-small-wink.gif[/img] that use to make that cover noise...i thought it was from my son standing on it shifting the plastic...i guess ill figure out what it was here soon..

 

You will need a clutch puller to get the primary clutch off.You can buy one for around $25 and it is a must for any Polaris work.

 

thanks for the tips guys....is the driven(secondary) clutch puller needed as well?...and are you guys buying from the net or locally...
