The engine was completely rebuilt last year(pistons bearings sealings everything..),and are running just fine.A chip was installed a couple of years back,some says it should give +10 hp?.last year my clutches was cleaned and inspekted, and the weights and spring on the primary was changed.the secondary was only cleaned and the spring tigthened one hole. all parts was original or equal.My track is changed to a new one that originally should be on a 01 Panther 550,and is much lighter than my old. Do anybody have any ideas?.PLease HELP!!

How old is the belt? It could be a lot of things not making it go faster. It could be geared different too. Who knows.

The tightening of the spring will put more tension on the belt, to let the clutch grab the belt better. You can always change it back and try it.

Norway - You said they changed the Primary spring and weights, did they put in the same ones, or change them to different ones? If so, what kind of RPM does the engine run, and what should it run for RPM?

I will say most likely you will need a helix with a little less finish angle.

Also, is the clutching shifting all the way out? If so, what is the gearing?

I do all the work on my sled myself(sorry if my english is bad) all parts in my clutches are original, so maybe i will have to check my gearing.The engine rpm is ok i think its 8200-8400. How do i check the shifting?.Thanks!!

Try marking your clutch sheave with a magic marker make a run and then see if the clutch closed all the way. then we will know more what to suggest.

Sounds like the rpm's are a little high for that motor. Also if your new track has bigger lugs or is heavier than your previous track that could slow you down as well.

if you upped the hp by 10 you should put more wieght to get the rpms in the right spot, buy tightening the secondary one more whole tighter you are slowing your up shift and losing top end right there. what was the top end to begin with. if you want to clutch for top end go to less helix angle and less compression. but i would bet with the extra power you could put more wieght put the secondary to stock position and maybe even gear up.
