I want to know if a 38 tooth rear sprocket would increase my top speed, and by about how much? I basically ride up and down a river (great with snow cause the sleds pack it down nice) and I need/want more top speed. I'm hitting the rev limiter in 5th. I had a new Polaris XC600 pace me, and I'm getting about 70 to 71 out of it. Thanks all.

 

No the 38 will slow you down, go with the 36 instead for more top speed...

 

I was just thinking that, so the rear sprocket, go smaller for faster top speed, front sprocket go larger for more top speed, correct? Thanks.

 

Put more air in your tires...quickest easier way to go faster[img]i/expressions/face-icon-small-wink.gif[/img]

 

You got it....

 

I'm at 4lbs all the way around, I'm not about to over-inflate the tires, that cause way too many problems down the road. I've learned that with my 95 Scrambler 400 4x4.
