I have a 2001 500 H.O. and I hooked up a tack to the engine. I want to try some clutching changes and I need to know what the peak engine RPM is. Has anyone tried the high altitude primary weights? They are 44 grams.

 

i also have a 01 HO and would like some more rpm as well,i wanted to install the 44gram weights also.where and how did you install a tach?? thanks,silverado

 

I haven't actually installed the tach yet, it's on order as well as the weights. The tach I seen was in the 2001 accessory book. The price is 49.99 and the part number is: #2873108 I plan on installing it underneath the warning lights. The dealer said insallation is easy. It should just plug in.

 

cool let us know how it goes.thanks

 

is the tach in the polaris access. book? man i would like one of those too. how much was it?

 

i read an article that stated "if the 500 spins 6800 rpm's or faster that crank will break!!!"
ride on!
