The clutch. That's why its mostly China girls. Its got a real clutch, not the centrifugal bs.
I will skip over the agricultural/generator motors and go straight to a lifan Honda clone, because it can be had with a real clutch.
The OP was also not comparing China girls to DIY builds. Everyone else did that.
My point was that your original comment seems to me to imply that unless performance parts we're readily available and specifically made for the bike/engine being built, then you didn't like the fact that people had to make their own performance parts and don't like those type of builds in general. Just saying that's what it seemed to me that's what you we're saying.
The DIY builds also usually don't need as many improvements as the 2 smokers lmfbo, because the engines we use for the DIY builds almost always make more power than a China girl right out of the box. You've done how many mods to your engine, and you're up to 4.5hp, meanwhile I disconnected my governor externally, got a high flow exhaust and a bigger Carb and I'm already up to probably 4hp. So you like your engine better because it needs all those parts and mods done to it?
The staff has been watching and is very aware.
Scotto, your bike is beautiful, and far more capable and advanced than my simple, by the numbers no mod kit builds.
But coming from decades of motorcycles, I require a clutch lever.
Same thing in my cars, gotta have a clutch. But thats me, not everybody.
