    Pretty much a basic and some what trouble free build. With the help of user cruiser66 I was able to get some bugs ironed out. I did add a gearbox oil reservoir to cure the "spiting" out the vent hole. Never use a soild 10mm bolt with no vent when running gear oil, or if you want your legs covered in hot smelly gear oil. Where the rear axle bolts up to the chain stays I welded extra metal to lengthen the "C" wheres as to adjust the chain for tension with out the need of the chain tension part. But biggest goof is not about the engine kit, but breaking my bottom bracket where the left crank attaches to (Over Torqued bolt). Try ed welding the crank on but was worried about the heat burning up the grease in the BB. Don't really want to spend $100 for a new Shimnano BB part. I guess I got lazy since you don't really need to pedal with this 4-stoke kit but must comply with the law stating that the bike must have pedals (and light and horn and mirror and brake light) Work in progress.

    Last picture is Dorkbike III, Plans are newer Honda engine, Belt drive and the newest gearbox. Few years down the road:rolleyes:

    that motor does look like a monster. Good job. I'm afraid to ask how fast it goes.

    It looks bigger cuz the frame is so small. Really tight fit in the diamond back frame. It's a basic Huasheng engine, top speed is a cool 45km/h @6500rpm constant with 50 tooth gear.
