This is the cheapest version of this kit I could find here and all the parts are there and in great shape. The instructions aren't great but Project Farm did a 4 stroke bike video with this kit and I'm using that as a guide so its nice that this is the exact same kit. This is not a plug and play Ikea furniture type deal so be aware you will need some specialized tools and knowledge about bikes, motorcycles, or engines in general. Still a stellar piece for this price, customer service was also very helpful and shipping was fast.

I don't know why someone doesn't make a clutch that works on these kits! It seems good for the money, but the clutches make it useless

It's a very good running motor. Tight fit but can work in the right bicycles. Fast delivery and easy to install.

Very good quality for the money minus the clutch it blew in the first day of riding less then 5 miles on the bike sadly but what are u going to do also the cast iron mount broke because I over tightened it my fault and the motor with the mount didn't fit I hade to modify the frame sadly but it workes now honestly I would rather have a 2 stroke motor kit with a aftermarket exhaust and pull cover cool for the build tho I'm still waiting for a refund that I was promised and did not receive

These kits are nightmares unless you know what your doing with mechanical stuff I have gone through 4 clutches and 2 of these motors the problem with the clutches is that there are chains inside the clutch that DONT COME OILED OR GREASED so I highly recommend greasing them before you ride or else within the first few rides the gears and chains will get destroyed
