Reviews
"I have seen all the videos on Youtube from people that have set their bikes up with one of these 2 cycle motors. In the video you will notice the motor does smoke quite a bit when the bike is sitting still. I am a pretty hefty person and the motor has no problem getting up to full speed and pushing the bike in the high 20's to low 30's MPH . I waited till I had a 100 miles on the motor before I started using the locktight to give the screws and cables time to stretch. I had to do the same thing....30 secs later the motor was up and running Overall this was a really fun project that you will be very proud to complete. Make sure to take a bike lock with you when you go places since you will draw a lot of attention."
"I've seen customers have issues, some from pics seem to be owner errors from over tightened bolts to blown motors in first rides. Know which bike is best for the build and learn how to mix fuel ratios and use top lubes and non ethenol petrol."
"I could ride almost anywhere I pleased,I had mine on a 28 inch Raleigh mountain bike and I could hit 35 40 mph the second to third day of having it ( after break in periode I rode 45 to 50 miles a day). When hunting for a motorized bike you can get ripped off easy I've bought about 6 different ones from various undisclosed companies... make the story short they were junk un modifiable or bolts would break easy."
"Do yourself a favor and avoid a huge head ache like I did and just buy an aftermarket NGK spark plug and chain prior to purchasing this kit."
"This motor is on my every day bike, And I do mean my every day bike."
"Be prepared for a project. THE GOOD. rear sprocket seem to work. Speedometer works. Gas tank is okay. THE BAD. everything else. Cylinder head spark plug threads. Spark plug looks like the threads were only machined half the depth they should be."
"The box weighted 25lbs, so keep in mind you will be adding about that much weight to your bike when finished, so it does feel a little off balance if your not the most balanced person."

Reviews
"The studs are not Chinese they are American-made do not believe any of the reviews on here there's absolutely nothing wrong with these."
"About 15 minutes after the final torque sequence on one side I was standing and talking to the technician when we heard a "POP" and I felt something hit my forehead (turned out to be assembly grease) we heard something hit the school bus in the bay next to this truck and land at my feet."
"A broken piece of the bolt remained in the head of the engine which required a great deal of tedious work and special tools to remove it."
"studs broke at 180ft lbs. caused me to buy a new head gasket and arp studs, my tech charged me 4 hrs to drill out the stud out of the block."
"Over hardened torqued them and they blew out of the heads a few min later ...one even came pre broken in the pack took us 600$ and many hours to remove the piece in the block."
