Im have a 400EX and I want to buy a 440 kit..I was wondering how much they cost and where I could get one...Also what would the top speed on a 400EX with exhaust system, twin filter, and a jet kit be? And what would the top speed be on a 440EX with the same mods, also would the 440 kit gve it faster acceleration and torque?

 

u can get a 440 just about anywhere, pick up a dirtwheels and shop around. The top speed wouldnt change unless u change ur gearing or tire size. Ive seen 440's with exhaust, cam, high comp piston, port and polish etc... taking 310-330R's! off the line all the way up to top speed. If u have ur 440 jetted right it will be a demon on the track, itll take a very tricked out R or C moto to keep up, banshees, raptors, z', preds will be left behind. All this also depends on the rider though!

 

if u want a could 440 but will cost ya some chiney ct got a kit 400 all they way!!!

 

what?

 

Say that again.

 

ct has a good kit but its some $
