Help!!!

[dirtbikeman101]

i have a pirhana 140 engine fitted into a ct90 frame. will a klx110 exhaust work? for some reason i cannot find the flange specs and size anywhere. i know this has a 1.26 inch flange size out of the head. any help is appreciated

I don't know the flange specs for the KLX 110, but I do know that an aftermarket pipe for the XR/CRF-style engines usually has a 32mm flange OD.

You may have to modify it for your ct90
