more top end
My brother has the sled, I've got the net, so here goes...
He just bought an '03 Polaris XC SP 700 (VES) with 1500 miles; he says its got lots of pull, but runs out of poop at about 90 mph; it is over revving at about 81-8200 rpm. He suspects clutch (64 gram weights now?), any suggestions? possibly a Heavy Hitter Kit? sprocket? I think he has cleaned the exhaust valves, but maybe not. Also, he is wondering what pop up valves are, and what do they do? any help would be appreciated!
Thanks.
