Well the one thing i do know is that you need to run lean. Less air = less gas. i just need to know if there is some ratio for jetting for altitude. For example, decrease one jet size for every 1,000 feet. Hear people talk about it but no one that i know, knows the ratio for 2 cycles.

I jsut recently put on some new PC pipes. What type of jets should i be running? The Stats: 2001 Pro Circuit w/ stock silencers K&N Filter no lid run at 6,500-8,000 ft

I have recently put on some PC pipes on my Banshee and am not sure if i am jetted right. The top end runs great but the bottom end is real sluggish. Is this typical of PC pipes?
