2strokespirit Posted November 4, 2007 Report Share Posted November 4, 2007 What kind of mods does it take to beat a YFZ450 piped with a K&N filter. I just read so much opinions on how the guys on thumper talk says how the YZFs beat the Banshees, until they are modified. Thanks Quote Link to comment Share on other sites More sharing options...

91banshee Posted November 4, 2007 Report Share Posted November 4, 2007 rider ,weight and traction are a big factor , weight loss is hp gain . a piped banshee with small bolt ons and a light good rider will beat a piped 450 Quote Link to comment Share on other sites More sharing options...

sheerider1026 Posted December 13, 2007 Report Share Posted December 13, 2007 i know a guy that has a shee with a fresh crank and topend, trinity stage 4 pipes, and thats it ( no port work) besides a modded shift star, and he can beat the yfz450's but he is a fairly heavy guy, so i guess traction is not a issue, lol Quote Link to comment Share on other sites More sharing options...

91tsiawd Posted December 13, 2007 Report Share Posted December 13, 2007 I've raced a couple of YFZ 450s with my Banshees and lost from a dig on a short run (rider/tires made the race) From a roll I had him by 2-3 bikes in the entire race (1st gear roll on). The YFZ only had a pipe, cam mod, and K&N, my bike had FMF pipes, Noss head 21cc domes, +4 timing, V force reeds, K&N pods, FAST Clutch, etc (every bolt on part) with a bone stock motor (no porting, STD bore pistons, gearing, etc). YFZ's are fast but with a couple of bolt ons it becomes a riders race. Quote Link to comment Share on other sites More sharing options...
4strokessuck Posted December 13, 2007 Report Share Posted December 13, 2007 I eat 450's for lunch. This past Sunday I raced one with some 470 or some big bore kitted Curtis Sparks piped yfz. The first race we launched even and I pulled about 3 bikes on him. The other race I was behind by a bike and a half and beat him again by a bike. I weigh about 190 lbs. and the other kid was smaller than me. I launch the hell out of second gear and flat shift her with the throttle pegged. Run that bike like your life's at stake. Shee can take it. Good luck. Quote Link to comment Share on other sites More sharing options...

530grafix Posted December 13, 2007 Report Share Posted December 13, 2007 My cub is powder black. So, i like to let them think they are pulling on me then i put the hammer down. And the look in their faces=prceless. Quote Link to comment Share on other sites More sharing options...
wacko2000 Posted December 13, 2007 Report Share Posted December 13, 2007 well last weekend was only my 2nd trip out with the fresh build, ran into some kid on a 450r with hrc kit, pipe, head work and some other shit.. He was a nice kid should us acouple of nice place to ride where we where at... anyways we where all talkin and the e says let line em up.. OKAY, lined em up from the start we where neck to neck and then I started pulling him hard in third, he couldnt catch up I kept pullin and pullin.. than raced him on his boys shee that was bored .50 over with T5's beat him on that.. we where getting ready to leave and he said lets give it a run one more time but from a rolling start.. that was even worse for him, he really had no shot, from 2nd on I just kept pulling him.. Im only bored .20 over and Im ported.. 15/40 gearing and +2 swingarm so I wasnt wheeling, really helps keeping the power down... Quote Link to comment Share on other sites More sharing options...
