I have a 2000 sportman 500. I'm asking for some ideas to help me increase the power of this bike. I would love to get it running like a H.O... Please comment!

 

Speed costs money how fast do you want to go? Cam and carb off the HO to start with. Drop the EBS. Roller Clutch and Clutch Kit. Porting and advance timing about 2 degrees. Pipe (the only mod I don't have cause I hunt). Don't add any more weight, in fact buy aluminum wheels you will drop 7 lbs per wheel right there (my next mod). Good luck.
