on ebay, some guy has made a 660 rappy into a740cc killer!! could this outrun a yfz450 and the 700 rappy? cos a hope it can because i am after a brandnew raptor soon[ 660 version]

so is it possible???what would that cost

this is the producvt code, to people outside rthe UK it on the www.ebay.co.uk not .com... product code is

4557653949........................check it out, also, some one has put nitrous oxide onto a raptor? aw cool. that would be fast

 

it could be bored and stroked to 740...thats all we know for mods, if thats the case its not THAT fast

 

its bored and stroked no big deal, is a 727cc on the actual bore, some people call them 727's 730's or 740's. if your worried about beating 450s find out how mich HP the 740 is making i bet its in the 65p range. a well built stock bore will make close to 70 hp if you do it right. Also they bore raptors into the 820cc range now.

 

how reliable are the 800+cc rappies? what is the recommend carb size for a bike that big?

 

i would think at that large, unless your a master mechanic and want to tweak it every few times out...very unreliable....but i'm sure someone one on here will beg to differ

 

a bored and stroked rappy not fast. unless a knucklehead built it. But it doesnt take all these mods to beat a yfz 450, heck i can beat em on good days with what i got. but yes that quad will beat the 700 rappy and the yfz.

 

the 820cc raptors are run off the dual fcr's 39mm carbs. and are reliable for what they are.,

 

Meaning as reliable as an unreliable engine can be. Comparing to a stock engine of course.

 

yeah, for being a 820ccis reliable, it makes big power, and big stress on the motor. cooling the motor is the main problem for a bore that big. 820cc is well into the waterjackets.

 

in what aspect is the bored and stroked raptor slow?
