Just finished my Mb today... powershopking 80cc kit on a 20 yr. old Giant mountainbike. What INCREDIBLE fun. What scary speed! Definitely going to get a helmet. The kit was complete... the only problem was the clutch cam was missing a roll pin or screw to retain it. Used a ground down nail and some loctite. I need to put some insulation (inner tube?) between the frame and the mounts to reduce vibration. Can not wait for tomorrow so I can add some walmart headlights/foglamps and a Black and Decker jumpstarter (already own the jumpstarter). It took me a day to assemble after gathering the required tools. I did not look at the instructions... I spent the last two weeks waiting on the engine devouring everything in this forum. And the assembly went nice and easy. Definitely loctite everything. I have been layed off since july (just got rehired) and did not replace any of the fastners or studs because of lack of funds. The bike was built entirely with the supplied nuts, bolts, washers and lockwashers. So far, so good. I put 60 miles on it today just cruising around and getting bugs in my teeth because of the ear to ear grin. Thanks, guys for all the help and advice... it made things go smoothly.
