if i got the clutch kit for my sp 500 h.o would i lose the lifetime belt warrenty? or should i get the k/n power kit, the power kit only increases the power by 15%, could i even be able to tell powerwise if i had one

 

Actually a 15% increase is alot, that would be about 6hp. You figure the HO got a 20% over the non-ho and that was a big increase. However it's hard to believe you will get that much out of a k&n power kit. But if it does, you will feel it. But I think it most likely only a 3-5% increase.

 

I have the Power UP Kit on my Scram ...I doubt you will ever see a 15% increase in power I noticed maybe a little power gain. But I am going to go with a clutch kit and Pipe to really feel the power increase.

 

Why not go with each
As far as loseing the lifetime warranty
I dont think so.
Just take the belt in and have them give you another
Their easy enough to change.

If I had to go with just one it would be the clutch kit
