1/4 mile or more

ok i got a 4mill ported shee running race gas ect.....check out my sig, and my friend has a yamaha 450 quad with pipe, open air box, cam adjust mod and rejeted........which quad would win on a wide open 1/4 race or longer.......he seems to think that i would have to let off after completely topping out so i dont blow up the shee and he would catch up and win

for that long of a race run a 15 tooth front sprocket,with the mods i read in your sig you will kill him every where.i spank yfz 450' all day long.

sounds like yer ready to rock.yfz 450 run hard right out of the box,i feel like too big for one when riding one but i think there a great quad. butt if he only has a pipe,filter and rejet or what ever it dont stand a chance against whats in your sig.if you got what you say you got then the yfz 450 is in serious trouble.

The 450s do not have that top gear as the Banshees do so your top speed will be pretty hot. In order to allow the engine to survive long pulls like that, you need to jet a bit fat, and run twice the amount of premix oil you do now. I would recommend 20:1 yamaR. Remember that as you add more oil, your fuel viscosity will increase and demand bigger jetting without starving the engine. Also, if your timing is way advanced, you might back that off a degree or two for good top end pull. Should not be much of a race!
