I was wondering what size carb are people using for the trx 90's racing mx. We have a big bore kit (not sure which size, either 104 or 107), with powroll cam. We have a Walbro carb on it now (again not sure which size) and we are not having much luck with it. We tried a rebuild kit but the trottle keeps sticking on it and we are not sure why. So we are considering just buying a new carb and arent sure which kind or what size to go with. Does anyone have any suggestions?? Thanks!

 

we are using the 26mm. are you using the stock intake?

bought it from icracing 1-800-414-2973
