I finished the homemade red bike, goes relay well, no shortage of power, motor is a strong runner, still needs a rear brake cable, I have a wooden seat but needs foam and a cover, This frame was built for a Villers 2 stroke and the frame rail was in the way for mounting the B&S but I had the remains of a Masport rotary hoe and whacked off the engine mount witch is adjustable, worked out perfect for this bike to get the engine offset and for adjusting the chain.
If anyone comes across a B&S V twin horizontal shaft motor I would be keen for the next project.
