Always wanted an hs50 but i dont like the idea of screwing with the laura. obviously, the drive system bears a striking resemblance to the french bikes. was thinking of a av10 or 103 swap... im sure that i could figure it out, the mounts will be and interesting hurdle tho, it appears that the bushings are part of the motor instead of the frame.... just curious if its been done b4...(it probably has)
