I have a 325 magnum 4x4 2000 model that has lost most of its drive power.
I have replaced the primary clutch & belt but it still is not working correctly.
when the bike is in neutral the primary & secondary work perfectly but when I put the bike in gear(high) the clutches only go out half way & when the bike is in neutral at idle the secondary spins as well, there is not a great deal of difference between high & low gear speed wise at the moment, any help would be greatly appreciated as it is very hard to find a mechanic in OZ who knows much about polaris bikes

Sounds like worn out buttons in the secondary. Some new springs wouldn't hurt in the clutches as well.

cheers mate i will give it a go, is it normal for the secondary to spin in neutral at idle?

 

[RVS Performance]

No it shouldn't that will make shifting gears difficult. The belt may be a little tight. Make sure you have the correct belt and that the clutches are aligned properly too.

cheers for your help mate, the buttons are worn as you predicted now I just have to wait for the new ones to arrive and replace them, hopefully this will be all the problem was.

No problem. Glad you found it and that it's an easy cheap fix.

Hi I was just wondering was your problem just the buttons... I bought one for my son and it's doing the same thing

I have to guess that it was the problem since he didn't post again that it wasn't fixed. Lots of times the problem gets fixed and we forget to post the results. I would second the above diagnosis. If the buttons in the secondary clutch get worn out the helix inside wears metal on metal as it tries to move the secondary clutch and has a hard time overcoming the friction. I would look at the primary clutch too. Pull the belt off and watch the primary. As you raise the rpm, it should move completely closed.

Ok,, yes my buttons are completely junked and it marked my helix all to pieces... My primary seems to be fine it's closing and opening all the way

I think the helix is still available from Polaris or at least it was the last time I looked. The buttons are only a few bucks each but the helix is probably a $50
