I'm installing larger tires on my SP 500 does anyone have any suggestions as to an exhaust and any carb mods to boost power?

 

put a UFO (ultamate flow optimizer) in you carb slide, it a snomobile invention but it works for anything with a round slide carb. Hot Seat sells them. there hard to tune if you dont know what you doing and it might be better left to the mecanics.

 

Hey Neil thanks for the reply. I'll run that by my mech,I'm pretty good with nuts and bolts but I'll leave the tuning to him. How's about a good aftermarket exhaust? I've been reading they can really boost power.
