honestly,best bet is to use a Real piece of steel and make a whole new motor plate.
that tinfoil plate on there now Will keep cracking...im on my 4th baja build already,trust me,i know this...:censure: they all fail.
it looks like they deliberately designed this to fail btw.
note the beef of the rest of the bike and the tinfoil engine plate,which also happens to be where all that torque is applied.
plus,i Hope the welder double checked your stand where it comes out of the motor plate for the jackshaft....because thats a problem area too.
nice exhaust!
