I believe 502 is the biggest you can make the engine thus far...

Another question, what is better with a full yoshi pipe, a 700r banshee or yfz450? Just the full pipe, proper jet (yfz and banshee), no air filter lid?

Max Power Engines has a 523cc kit for the YFZ. From what I hear the 523 Max Power YFZs are undefeated in the 500cc to 700cc unlimited modified four stroke class.

Ya, and they prolly have to rebuild them every race [img]i/expressions/face-icon-small-wink.gif[/img]

What kind of question is this? Why would you ask this? I assume because you're shopping for a quad by comparing which performes better w/ the pipe you like, but that's pretty pointless, they perform to differently to shop like that .... also, they are Raptors, not Banshees.

Max Power has had great success with the 523 kit, it is expensive, it comes with a new cylinder not a bored out one, and I have read that it actually runs cooler than a stock motor.

What type of riding will you mostly be doing? my little 439cc has beat out every 439 with similar mods, last weekend I beat a built 500cc Honda, with my bolt on bike, you may not need an engine builder to go fast. set up has a lot to do with it.
