Donor Bike:
Test fitting the new swinger:
Different pics of swinger with motor in (not finished, still have to brace it better):
Still have a bit of work to do yet but its coming along. I started this project because I twisted the original rear end and snapped it in 3 places. The 300ex needed a ton (all the chassis bushings shot, and all the shocks were blown, and the frame was cracked) of work and wasnt worth fixing but the motor ran great.
