Can anybody tell me the difference between the big bore kit Ims440ex at 285.60$ and the Ct440ex at 345$ ? Ct have a webcam(don't wont race cam),does it make a good difference compare to stock. Would a XR400 cam can do a big difference?
Did anybody see a big improvement with head work(porting,spring valves...)

I believe the IMS kit has a JE piston...not sure about the brand of the CTracing. Anyway, go with a high quality piston like the JE (wears slow similar to the stock piston and has less clearance for potentially more performance) and not like a Wiseco piston (that is primarily a cheap piston that will not last near as long and has more bore clearance). I believe WEB CAM's web site is webcam.com, but not sure. Call them and check into it (take a deep breath first 'cause you will be looking at buying a cam-core charge on the cam-hard facing rockers also which they say you have to have). Good luck!

Why are you selling your Big Gun exhaust system?

 

To pap400ex, I sell my Big Gun exhaust because it's to loud for the camping where I ride in the summer, and I whant to modified the motor to get extra HP that that I loss.
