    This is the 2nd project that I&#039;ve built. Although I haven&#039;t even come close to breaking this engine in, I&#039;m impressed with how smooth this engine runs. It is a step up from my first kit which was a rather unbalanced and power anemic old school China Doll.

    The Motor kits are great and well worth every penny there great reliable motors I’ve ordered from several companies over the years and so far this company seems to have the best motors and quality this year I have ordered five motors for myself for my YouTube channel so far every motor I have ordered for myself spending well over $1000 in the last few months

    I&#039;m back to order another one of these. I sold my other one for $600 as it was the fastest, and most reliable kit I have ever seen, let alone bought. I have built over 28 bikes and been through all the crap for sale on the internet. This kit is EASILY worth double the price as all the parts and engine are top quality and they all work even better than expected. I never review anything, yet also never have been so satisfied with anything I have bought sight unseen but I&#039;m telling you, try out one of these and you can thank me later, and you will, I promise!

    The clutch lever was upgraded the tank was in perfect condition the carb was perfect right out of box everything was lubricated the piston and rings were facing the right way all the ports are close to perfect the case is indeed stuffed no other engine ive ever received had that much compression clutch didn&#039;t need any adjustments the bottom end torque is amazing i did

  • Best motor there is!

    Posted by Robert Palma on Jul 5th 2020

    I have bought 2 of these and now ordering #3. The entire kit is high quality, and the new motor has more torque and power than any 80cc out there. I broke them in gently and slowly and the payback is like riding my Husquavarna CR125!. Lots of low und grunt, it pulls up any hill at any speed with a 36tooth rear sprocket, and with a banana pipe and a little tuning hit 47mph after break in! You simply cannot find a better motor, better put together kit, anywhere and you cannot beat the price! 1 very happy camper here!

    This motor is extremely powerful right out the box. Can&#039;t wait to see how much quicker it can get once I break it in.
