Okay, I've gotta say this about the M101...…...about 12 or 13 yrs. ago, at Circleville race track, they had a really good race.
One of the lighter weight guys won it, but I was so impressed by the way the modded M101 pulled that huge guy,Chris of Mopedwarehouse,almost to victory.
It was plain to see that the engine was the most powerful there.
BJ tried to sell me a new one years ago, and I wish I'da bought it.
