speeddmn, ill race you, i just came from glamis and i am going again for easter, ill let you know what weekend we will be there............... 85 atc 250r (310ct engine) maybe faster by april..

 

250ctracing310kit you better get someone else to do your motor if you want to run with me. Ask Rob from Colorado how my 440 beat his CT racing 350 in his 250r quad. Shane if I tell you all my secrets I won't be faster than you anymore besides someone else may pickup on it. ssssssssssshhhhhhhhhhhhh(raptor03) might be listening.

 

By reading this thread,it sounds too me NOTHING will beat a properly built 400ex,must be a west coast thing

 

Blue thunder- LOL

 

That is correct Bluethunder. I have even seen a few rappy's dressed up in red plastics trying to act like well tuned 440s but i did not work they still got there stompin's[img]i/expressions/face-icon-small-happy.gif[/img]

 

dont shoot yourself in the foot. i run with CT built TRX350 powervalves and im not a CC over 250 and have no serious porting.

 

HA2, how does that work exactly? if i'm .020 over, does that mean it goes from a 246 to 248? Not sure how that works...

 

I think so, the 465ex is their alky big bore i think...from the vids ive seen of it it is extremely extremely fast

 

roughly.

.0007854 X 66.20mm bore X 66.20mm bore X 72mm stroke X 1cylinder + 247.821723072cc's

 

thanks ha2!
