310 or 330 build?

[sleepinR]

Hey guys I was just wondering what company everyone suggests to get a 310 or 330 kit...i am looking for a bolt on kit though, i dont want to go through the hastle of messing with the cases yet....let me know what you guys think...i have been looking at CT or ESR and i'm just not sure which would be a better fit...i ride in the woods(fast)...and have plenty of open fields to open it up in...Thanks

to tell u the truth, i'm not a big fan of the major companies. i feel u are really paying for the name, but i just finished building a 250r that had a esr 310 kit with trx9 porting and a esr trx5 pipe and silencer, and it's probably the best running R i've rode. i have it jetted perfectly, and it's got excellent power, very smooth. my buddy has a ct330 with the machined cases...and it just seems to be a bit much. more energy is wasted controlling it.

so a 330p/v has to have machined cases?

I'd stick with a 310 kit if you don't want to touch the cases. I always thought the bolt on 330 kit was cheesy. If you want to go 330, do it right, and bore the cases so you can go with the thicker sleeve and have more bores available.
