What colour of clutch spring would you recommend for a 425 Magnum. I want more low end bout not to loose top end if possible. Where can i get it. Are they hard to change. Would a K & N air filter do anything for preformance.

 

HPD-inc.com, Hotseatperformance.com, Ritter cycle racing...ad in back of Dirty Wheels. These companies can help you out.

You want your 425 to run great and have good topend check out how mine is set up.It will run with my 400.see my signiture. Brad

 

Oh yea my white primary is Polaris and the blue secondary is Aaen.

 

ok, are your springs set for max preformance with your pipe. mine is stock except for a K & N soon. What colour of primary should i get. Would i be abel to get it at my dealer. are any special tools needed to change it. Will it loose top end for excelleration. Do you need to set something with the weights too. Is it hard?

 

Matching springs for the pipe is not important on 4 strokes.Get you a white Polaris spring pull the cover take the 6 bolts off the front clutch swap springs put it back together.There is a pipe for yours on Ebay right now with a buy it now for $115 its a Supertrapp.If you want the url pm me.
