    Just a few quick notes about product development at EZM.

    We are currently sourcing vendors to make hard to find parts for a few 4 stroke motorbike motors. We already had an American company make mushroom lifters for the Whizzer NE motors, and the inventory is almost exhausted.

    We are still working on the Mach III drive system and just last week MaxTorque sent us the latest weights & springs to change the "stall speed" on their clutch. We started this project almost a year ago, and because of the high demand for our current system we won't be putting the new system into production for several more months.

    Several dealers have designed some really great new mounting systems, and from the early reports it will be far more universial than current offerings.

    As earlier posts have indicated, and because of dealer demand we are shipping kits to dealers for re-sale.

    Because of testing we still haven't contracted the fab shop for final belt cover design. We hope to reduce the cover to 1 3/4" prior to large production runs. We just weighed the new system and looks like 5 pounds will be close in the final weight.

    If anyone, dealer or not has any ideas to improve the EZM system, please let us know as the EZM is to be dealer/customer designed.

    Every single kit will be inspected by me personally prior to shipping [so if it is wrong, it is my fault].

    Have fun,

    best of luck to you.

    Are these innovations to be Whizzer specific or will they fan out to EZ, and maybe happy time, drive trains?

    would the new clutch "stall" provide a higher engagement rpm to make some of the 2 stroke engines a consideration for the use of your system ?

    hi Steve
    What 2 stroke engines did you have in mind?

    The 50 cc HuaSheng / Honda GX 50 have a 5/8" shaft
    but any engine with a shaft could be used providing
    that they have a suitable rev range

    Separate transmissions are not being sold right now anyway

    Hi DetonatorTuning,

    The new system uses the clutch in the output stage of our drive system. MaxTorque has been working with us to make a clutch engage at different speeds. We won't have the clutch installed directly on the motor because our motors RPM is higher than the stock stall speed. We considered using different spring rates and special shoes to raise the stall speed, however it still made the motor and drive system too wide [for some reason a lot of manufactors want us to be "Bow-Legged" LOL]. In order to keep our system trim [appox 2" wide] and avoid the process of making "one" off proto-types for testing, we decided to use the same master plate with a few minor holes added or moved.

    I don't to want give away the entire design because a few other companies are working on similar systems. I will however tell you it isn't gear or chain driven directly from the motor. It uses a MaxTorque clutch with a special stall speed. The clutch isn't installed on the motor crankshaft, the clutch is the final drive [no secondary jack shaft or gear reduction sytem past the clutch] to the rear wheel. The clutch is completely supported in the system. There is no oil, grease, or case sealer needed.

    Sorry Steve, we lowered the stall speed and would be moving in the wrong direction for a small 2 stroke motor. 2 stroke motors have very little power at low RPMs and this clutch would engauge too early if affixed to the crankshaft, however the EZM Drive system could possibly be attached and set the clutch to hook up around 3000 RPMs [motor RPMs, not clutch speed] it might work. Sure is an interesting concept, whish I had time to try it.

    Have fun,

    Just a quick product update,

    Recent tests in Dawson Springs, KY on both the "Roller Road" [Dyno], and the Dirt Drags, yeilded the following results with the EZ Motorbike kit.

    Ron Dow [TX] 40 MPH on the Roller Road [1st place]
    Mike McWhirter [IL] 35 MPH on the Roller Road
    Quenton [NC] 34 MPH on the Roller Road
    Quenton [NC] 1st place Dirt Drags
    Mike McWhirter [IL] 2nd Place Dirt Drags

    Have fun,
