    Are these hoot gearboxes notorious for breaking down fast?

    If you can find a an engine with the same bolt hole pattern and clutch diameter as the gearbox then yes.

    That's what I've heard too but I can't say so first hand.

    Ic, but couldent you run the chain from the motor to the shaft of the box via chain? To look like a board tracker?

    Hi mezzenger, I am not in tune with everything being made, BUT I do know that EZMotorbike makes the Q-matic, and the Pacesetter drives especially to fit HauSheng and Honda GX50H 5/8 keyed shaft engines, also the internal clutch model of the Hau Sheng (with special adapter we make).

    The Pacesetter is also available drilled to bolt right on to the Harbor Freight 79cc Greyhound, and the 99cc predator models.

    It is adaptable to many other engines, but these are the patterns I am currently aware of. I am currently interested in mounting one to a 3.5 HP Briggs and Stratton Vertical tho I am not sure how I will bolt on to the old engines that I currently have.

    I hope this helps answer your question.

    Mike

    I'm kinda new to the 4 stroke relm of MBs but I had a 4G fail on me twice inside of the first month of use. Now I'm looking at getting a CVT pocket bike transmission. Been eyeing a few that are surprisingly much cheaper than the Grubee 4G or the older Bikeberry 5G single chain & the clutch drum & bolt pattern looks like it would fit my HS 142F. Can anyone let me know what pocket bike CVT transmissions can fit my 4 stroke motor? I'll attempt to post the measurements of one CVT I was looking at getting.
