Why does everyone just build MB’s. With China girl motors? Just curious. Very few staton, gebe and friction drive bikes with auto clutch. Not much recent in the way of custom builds. I see a few non kit motorized bikes I saw one with a ryobi and mark’s 97cc bike. It gets to the point I’m tired of seeing the same flawed engine being used. I’m not a racer I just like to ride around. Yes I know they can be modified and all that but we’re talking about an engine with no markings. I’m pretty much a 4 stroke/jap 2 stroke guy now. No wonder they have so many flaws there’s no brand name. Even Lifan and Harbor freight predator engines are of good or semi good quality (Chinese). Low quality 2 strokes wear out too fast. Previous Japanese designs even being 2 stroke could last a really long time like the old purefire Tanaka and mitsu which are gone now. I guess I got here too late. Even if you professionally build a CG you will have problems with the stupid clutch assembly it almost always oscillates and wobbles. Did it on every motor I’ve seen so far 3-4. Little things like the 3 pins holding the plate to the clutch- one of mine came mislodged and I could move it with my finger. It then was scraping the clutch cover. High revving and weird throttle response I didn’t like either. To make a cg semi good you would have to replace all internals just leaving the case. The cylinders are junk and the sleeved ones are incorrect. There is improper shimming on the wrist pin. People have said their crap girl has ran for 10 years but don’t reveal how many miles. There are garages you know that you can park a bike in for several years. I tell some of these people just to order a Chinese moped/scooter and have it shipped that way they can be legal but most of them are too young or have done the old 4 wheel intoxication. Why go 30mph on something illegal when you can just get something with a proven 4 stroke engine that can last in the 10’s of thousands of miles and the bike can be registered. At this point I’m willing to try out a real moped and get a plate . Be my summer ride and work on my class M at the same time.
