Guseting 250r frame

[pantera1975]

I was wondering if anyone else does it when putting in a 310-350 big bore In a 85-86 R? I gonna trail ride this thing.

In my opinion, running a bigger motor shouldnt have to make you gusset a frame. Unless your using that power to do some stupid stuff.

I ran a 265 Duncan PV +4stroker motor in mine for almost 2 years, Bigger cylinder, and yes I broke and frame and hairlined a few others. But thats cause I was MX'ing the frame and beating on it WAY to hard.

Youll be fine trail riding it
