I have a raptor 660 with an HMF full system jetting and intake. Today i got smoke by stock yfz 450. is this supposed to be? it was a drag race across a field and was not even close. what is up?

 

[FullBore660rLE]

is there an answer ou there? this boggles my mind

I don't think you should have got smoked, I have a stock 660 and against my buddy's stock yfz he will win, but usually by not more than a couple lengths. Although, since that last race he has put in a Trinity full system, intake, and stage 2 hotcams, now I get my ass handed to me. When it comes down to it, it usually all has to do with the rider, not to bash your riding abilities or anything, but that shouldn't be a blowout, try switching machines with him and see who wins.

way ahead of ya switched riders same results ruling out skill as a factor :thumbsup:

Well then I guess the only other question I have is, what do you consider getting smoked? How many lengths does the YFZ have on you by the end of your race. I call getting smoked a KFX400 trying to race my raptor(about 10 lengths).

 

[FullBore660rLE]

a solid 3-4 lengths anything that isn't within a quad length is a smoking wned:

My raptor have some stuff done to it (airbox,filter,exhaust,jetted) and I stay about dead even if not a half lenght or so in front of my buddies 2006 YFZ450.

 

[FullBore660rLE]

what pipe are you running because the hmf says low to mid range power so does this make it fall off at top end

 

[FullBore660rLE]

still not sure if i should be getting beat.......

i have a completly stock 05 660 and the only stock 450 i am having problems beating is my best friends ltr 450. i can jump him off the line but when we get in 4th gear he starts pulling on me. as soon as i sell my dirt bike i plan on buying a ct racing exhaust,rejet, loose the air box lid and try freez clear tube method . then i think i will smoke the 450

alright starting to think something might be wrong with my raptor. it seems to fall flat in high rpms..
