just had a new clutch and belt put in and the tires only start to move at 2900 rpm it seems to take a while to get going.I can`t remember what it use to engage at before but it seemed quicker.the clutch was cracked in 3 places thats why i replaced it.

 

you either have the wrong spring or weights in the primary

 

polaris white spring that was in my 500 before. i will have to pull the cover off tomorrow to check the weigts but i do not think it is a weight problem because it all came in a kit and dealer put it together. i am not sure that`s why i asked the question here about the rpms.

 

i put a white primary spring in mine and my clutch engages at 3300 rpms

 

so i should go back to my stock spring for quicker engagement.

 

02 500 Scrambler with white sping engaged around 1950rpm with stock weights
yellow spring 2300rpm with 10MB weights both with a TEAM roller secondary.
On your 400 if you want to lower the engament try a siffer secondary setting or stiffer spring.


On the higher engament on the new clutch check to be sure the secondary preset tension is right.Spring could have slipped out or could have been installed wrong.
