[Got nads?]

Any other companies besides nmotion make a 500 big bore kit?

Four stroke tech. Gt thunder has a 490

Does GT thunder have a website?

There are sleeves out now that will allow you to run a 99mm bore in a stock cylinder. Its a steel sleeve, with a wet design, I have one in my cylinder, and I will try to break it with the same piston that broke all the stockers.
I will let all know if a month if it holds up.

15/38 with 22" and the 530 rips threw those gears like nothing. i'm thinking 15/36 with 22" is what i'll probally use.

good to hear your 520 is ripping

It is an amazing arm stretching, gutt wrenching, butt puckering, chain stretching, tire shreding, terrrain chewing power that everyone that rides a 450R should experience i tell ya,...
