Coupelx Posted August 9, 2007 Report Share Posted August 9, 2007 I am getting raped by yfz's and the like. my cousin has a 04 yfz 450 with a pipe, jets and k&n. he is on the stock tires and i am on maxxis razors. He simply destroys me even from a roll. He admits my banshee should beat his 450. Specs: Rebuilt motor with maybe 30 hours on it. Trinity Powerflow Intake Kit Trinity Stage IV Exhaust System V-Force Reeds Trinity Stage IV Standard Head Dual Aftermarket Flatslide carbs (dont remember the exact size but bigger than stock) no airbox lid The plugs look great! Do i need different gearing? I am thinking of an adjustible timing plate for sure. Quote Link to comment Share on other sites More sharing options...

Michael Jackson Posted August 9, 2007 Report Share Posted August 9, 2007 something not right,, its one thing to lose to a 450 from a dead stop,if u launched bad or bogged a gear cause they have great torque, b ut u should easily catch up and pass by 4th gear, but if your coming up next to him , arleady rolling, you should just walk away, those 450s shouldnt touch you once your in 4th gear Quote Link to comment Share on other sites More sharing options...

Ill run a compression test tomorrow and post the results. i get through the gears fine. He is somewhat of a better rider but i dont think that would be whats wrong here especially from a roll.

Coupelx Posted August 10, 2007 Author Report Share Posted August 10, 2007 Compression is 148-150 on both sides. Test done with the motor at operating temp and at WOT. Both plugs out. gearing is 13/40 Quote Link to comment Share on other sites More sharing options...
fastbanshee8 Posted August 10, 2007 Report Share Posted August 10, 2007 Gear that damned thing up. With a 13 tooth on the front, you've got to be spinning like crazy. Go with a 14, or 15, and that should help a bunch. Launch in 2nd from a dead stop, and that will help it hook up better. Quote Link to comment Share on other sites More sharing options...
locogato11283 Posted August 10, 2007 Report Share Posted August 10, 2007 you should be beating that 450 with no problems. gear up one in front and then see what happens. if hes spanking you that bad maybe its not your gearing. maybe you arent a good rider. id think even with 13/40 gearing youd still be able to pull on him.

RagunCajun Posted August 10, 2007 Report Share Posted August 10, 2007 (edited) I guess im the only one that says the banshee should be losing. I used to lose with bolt ons. 450's hook up so well offroad too from a dig. Now from a roll i used to be a little quicker. If your bike is running well i personaly wouldnt tinker with it. I would accept it's slower. Then id save for a port job and supporting mods You wanna beat em, go ported. Then even if you have a shitty start, miss a gear etc, youll still pull on him and pass him :ohmy: Edited August 10, 2007 by RagunCajun Quote Link to comment Share on other sites More sharing options...
