  • Firestorm Zeda 100

    Posted by Steve on Mar 13th 2020

    Worked well for the first half hour of use, after that it made an awful grinding sound and the engine had no compression. After doing a live chat with the company, we figured out that one of the piston pin retaining clips had broken and badly scored the cylinder and piston. anyways, the engine seemed to be good quality except for the fact that the clip was not installed properly. Note: this was only an engine assembly issue and can be easily fixed. otherwise, it seems like the best engine on the market!

  • Amazing

    Got this engine kit after quite a bit of confusion as far as the delivery goes but finally got it and been riding it on a brand new red Cranbrook from Wally World. Man this thing is powerful. Been riding it two weeks now and still haven’t opened it up yet but mainly because I don’t want to go that fast. It hits 30 mph with no problem at all and wants to go faster. I’m sure it’ get to 35 if I wanted to. Has great torque for take off power, even with a 36 tooth sprocket. Anyway, love the engine. Great purchase.

  • 100cc motor kit

    This motor kit does not fit well into the zeda screaming demon v2. I had to modify the frame to make this engine fit. There is no room I'm the zeda screaming v2 for a upgraded carburetors. Other than that this is the best motor I have seen in a bike.
