See!! I have to have something going on with my bike. TOP TOP speed is 35Mph on my SP335. I need to check some things out. Just haven't had the chance lately.

 

Buckeye400EX, It takes a long flat run to hit 45. It hits 35 easly then takes a long time to climb from there. So you may need a longer run .

 

My Xplorer is the same way. Goes right up to 45 or 50 or so, then slowly climbs to 60. I think it is just the nature of Polaris to do that sort of thing.

 

I had 7 miles of flat ice with a thin crusty snow topping for good traction to get up to 45mph. 35 was all she'd do. I guess I could have been slipping some. ?? I'm 180lbs so I don't think it's me. I need to check things over good, air filter, exhaust, throttle adjustment. I have a new belt on it, so it couldn't be that. ??

 

Does anyone know of any mods that will help low and or topend? What kind of clutch springs are you guys using? And would the 34mm carb work better than the stock 31mm? Thanks.
