rjayb Posted September 5, 2014 Report Share Posted September 5, 2014 What's done to these 450s? That's what I'm wondering. I have a pretty built YFZ and it can't even touch my Redline stock cylinder. 1 Quote Link to comment Share on other sites More sharing options...

rjayb Posted September 7, 2014 Report Share Posted September 7, 2014 A ported 421 serval should crush that 513 yfz. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted September 7, 2014 Report Share Posted September 7, 2014 A ported 421 serval should crush that 513 yfz. Depends on traction. Quote Link to comment Share on other sites More sharing options...
dave5.0 Posted September 7, 2014 Report Share Posted September 7, 2014 I'd hold off on the big ass carbs. Still pull almost 100hp with 35s. I dumped mine. Made a buncha room. 1 Quote Link to comment Share on other sites More sharing options...
rjayb Posted September 25, 2014 Report Share Posted September 25, 2014 I'd hold off on the big ass carbs. Still pull almost 100hp with 35s. I dumped mine. Made a buncha room. I'm with this guy. We made those kind of numbers on 28's as well. Quote Link to comment Share on other sites More sharing options...
