Need some help with clearance problem

[dropndestroy]

Im working on my first build and im working wit a 70s 26in schwinn beach cruiser wit a ebay 80cc kit. i could not use my stock crank arms cuz they were to long and would hit the stock muffler i put shorter ones but would b a pain to pedal. i bought a extended muffler off ebay and im still haveing clearance problems wit the muffler. wat are some ways around this.

i havent started the motor or anything yet i still workin on the mounting

Crank Hitting Exhaust

Heat the pipe and bend it?

My Grubee pipe was way off [ 80 cc ] Remove pipe before bending, heat cherry red,
twist flange with pipe wrench, with pipe secured in vice. Re- bend to gentle out curve by
heating, and bending, using a long bar to bend flange away from muffler.

Buy an SBP expansion pipe. Aside from great slip fit adjustments, it produces great hp.
