Belt drive kits for the basic 80 cc two stroke

Hough,

The Schwinn Spoiler frame is different.

You can be assured that I have looked this frame over very carefully.

The idea is: don't alter the original bike! Add an engine without cobbling-up the rest of it.

I should have been more specific, Jim. I was referring to the original poster's issue.

Hi everyone,

Sorry I haven't responded to this post earlier, but my little machine shop is working overtime! There are several ways to convert to belt drive and several have used the rear belt drive system on the new EZM kit. Simply install the Whizzer rear belt sheeve and make a "V" belt pulley to fit on the output stage of the motor gearbox [or drive system on the EZM]. Our EZM kit is setup to either use the chain sprocket or pulley at the output stage of our drive system, and the rear belt sheeve can be purchased from any Whizzer dealership or from Memory Lane Classics [Ohio]. The sheeve from Memory Lane Classics is a repop of the vintage assembly and only requires a series of washers, nuts & bolts to attach, whereas the unit from current Whizzer sealers requires the brackets [more expensive] to mount to the wheel.

Have fun,

I would be concerned if one was to put a belt drive on a HT unless you have a pull start HT then it should be ok because if you bump start it will the belt hold? Also there's the gearing. It seems a belt drive needs a bigger pulley on the back wheel to distribute the load a bit better on top of getting the right gear. With a HT you'll need that rear wheel pulley smaller and that may add to the strain of the belt.

Just my 2 cents.

Large, about the only way to start a Whizzer is to pedal it (whether it's on the center stand or if you're riding it), so the belt can usually take the strain of a bump start. That is, as long as it's a decent quality belt like a gates, NAPA, Goodyear or similar.

doesn't the compression release allow the whizzer to turn over a little easier?

Kilroy is right Large.

I'm using Browning belts that are rated for 12H.P. at 2,000RPM. The HT countershaft spins at about 1,400RPM near the upper end, and the engine produces ? < 12H.P.

The critical thing with cog belts is tension...they must be tensioned correctly at all times.
