Hey anyone who can give me the best advise on this would be greatly appreciated. I have a YZ426 that I dirt tracked for many years but now havent raced it in 4 years and quite a few years ago I did some atv racing but I now would like to go back to atv racing and since I have this bike still sitting around which I can use the motor off of I figure it would be cheaper for me to build a quad than buy a TRX or YFZ anyone that can give me some suggestions as to what frame / swingarm / suspension / and any other info you can provide it would be greatly appreciated.

Thank you
