IMAYCC 80cc Bicycle Engine Kit, 2-Stroke Motorized Bicycle Kit Fit for 26-28" Bikes, Bicycle Motor Engine Kit with Wired Digital Computer

Would recommend getting one easy to install and run really impressed with the power of it it goes about 35 up hill

For me, after four times with this kit, I'm impressed. My first one was built in early spring last year, and is still going straight and strong. They are very reliable once the little bugs are worked out. It takes a bit of tinkering during break in. Micro adjustments will lessen the stress on motors, which can be fragile because they're not metal.The best mod you can do is put cut pieces of tire inner tube to fit in between the engine mounts and the bike itself. This almost free mod, is the best thing to keep it from vibrating things loose. And a close second is the brakes... If you have to GO! You need the WOAH 😉If you want more performance, start with better carb and/or an exhaust pipe with expansion chamber.adjusting the clutch . making sure the chain and everything is lined up right. adjusting carb and breaks, all of these things are necessary and very important so that your project will last.It's best for longevity and performance to break in the engine slowly, with a bit of extra oil in the fuel mixture.My personal IMAYCC 80cc procedure is:30:1 which is 4.3oz of oil per gallon for the first 3 full tanks. Try to vary throttle settings a lot. After the break in tanks, a 40:1 mix is my recommendation for normal use. If a nut/bolt is going to come loose, it usually happens during the break in and "shake down" rides. I use a torque wrench for the important hardware such as engine mounting bolts or chain tensionersI like the size of the tank... Looks average, but is bigger. The small fuel lines get hard and need replaced after a season of riding to prevent leaking next time. They will hold out for quite a while with regular use, but if it sits a lot they will need changed sooner.If the engine seems to be carbonized and sooty, add a couple tablespoons of ATF to the fuel, then run it dry.These kits are awesome! And fun to build! Any questions you could possibly have, are answered easily through a YouTube or Google search. Most 80cc engines have the same processes for maintenance and repairs.Enjoy, Friends 🤠

JUnk, Junk, Junk, Did I mention it's junk?Problems right from the start!Got it assembled, fairly easy since I have done 3 similar in the past (not this junk brand) and when I tried it out, the clutch would not engage because the pin they use was not long enough, that took an hour to pinpoint. Went to the farm store and got a bolt, cut it a quarter inch longer and installed it, that lasted for about 8 stop and go cycles and then started to not engage.Pun in a different cut-down bolt and lasted through about 8 cycles and started to not work again.Pulled clutch again and checked engagement rod and discovered that the bottom "lobe" if you want to call it that, of the engagement rod was wore from being a square shape to being rounded after just 16 times of starting the engine.Filled in the edge with the welder and ground it down so it would turn smoothly and assembled it.Got it running and took it for a ride and the muffer decides to split apart, comes off and bounces into the traffic lane where it promptly gets hit by a city bus and flattened, mind you, the engine has been started and ran 17 times and has no more than 3 hours use.I get home, cut the exhaust pipe pipe straight and weld on a lawn mower muffler, get it running and after a dozen or so starts, the clutch is acting up again, tomorrow I will make a new engagement pin out of a Grade 8 bolt and see if it lasts longer.There is no option to contact the seller and since the muffler that came with it is gone, I doubt if they would take it back.Learn from my mistake and keep scrolling past this item, you will be better off as this POS is not worth the time or money.

Bought it when it was $200 now they changed it to $160. I got it Assembled and started and when I was letting it warm up it was smoking from the motor, then after I rode it I noticed their was oil on my bikes frame from the motor. At first I thought I didn’t tighten the exhaust very well but then when I got down to tighten it I saw there was a crack in the motor. very disappointing! After some time of riding it I tried to adjust the idle speed and nothing happened so I unscrewed it all the way out thinking maybe it was stuck then the motor died and the throttle wouldn’t move. So I took the carb apart looked inside and saw the spring was bent and was getting stuck. I can’t find a spring like this anywhere and then I noticed the guide pin was totally flat and the motor was only running because it was stuck on the idle adjuster. Ended up buying a new aftermarket carburetor. Time and money wasted putting this thing together and they won’t refund me or email me back.Some tips:1-Make sure your wheel alignment is good or the chain will fall off. 2-The clutch might come too tight you’ll know if you can’t spin the wheel with the clutch in. 3-DON’T WASTE YOUR MONEY ON THIS KIT BUY ONE FROM BIKEBERRY.COM INSTEAD❗️❗️❗️ps- I cleaned the oil off the motor so you can see the crack.

This small motor is very good and i do recommend. It is not really hard to install and have taken it around 700 miles. This product is very good and the only thing that i had to replace was the cdi that came broken but that was because the person that delivered it was very rough with it. If your motor does not start and you have tried a lot of stuff, this could be the case. This part is only about 10 bucks. I also replaced and gas tank because I go really far at a time and just wanted a bigger tank. After a while, you will want to replace the fuel lines and filter because they will get dirty over time. People are complaining about the carb being cheap and bad, yes it is cheap but it gets the job done. I go around 30 to 35 miles per hour with the stock carb. If it really bothers you that much then just get a better more expensive carb. I really think this is worth the money and if you have experience with working on stuff and building, this is a fun,cheap, and easy project for you.
