Ocscully, it mounts right up to the clone (huasheng).
biketec, that's my main concern, however there is a bearing on both sides of the gear so we'll see.
I want to see if it's worth a "hoot" before I divulge too much; if it's good there are better sources than where I'm gettin' it. I'll have it in a week and I should be able to give an initial report in a couple weeks.
