80cc 2 Cycle Engine Motor Kit for Motorized Bicycle Bike

So it came with everything advertised and it shipped fast which i was happy about the chain guard however does not fit an the chain tensioner does its purpose but its cheap shit and im scared it will fail on me during one of these rides this is no fault of the seller but the manufacturer all these kits have the same parts instalation took 4 hours for me and i wasnt that motor literate great first project for someone wantin to get into automotive you will need serveral tools however look on youtube theres se great instalation tutorials that also cover tools needed i wanted to put 4 starts due to the instructions for kill seitch instalation were incorrect but the asker kindly asked me to direct problems to him rather than leaving a negative cment which was thoughtful in a way correct wirering is black from engine to black from cdi blue to engin to blue on cdi and yellow from kill switch black from kill switch is grounded to your bike i put mine into the front engine mount not on the engine but the frame is being held on by the clamp for the engine sellers instructioms will say to put black to the other blacks this however is incorrect and the switch will mot work which is very dangerous

They wont start...I bought two 80cc motors; one for my bike and one for my wifes bike..my gas tank was defective and they wont answer my calls. I would not recommend for anyone to buy these and their directions in the manual are also not correctly written and not all parts were in the kit and some of them were also defective...people are having problems as it is with the way the economy is and we are trying to save money by riding these bikes and when u spend almost 400$ you would expect at the very least everything is up to par inside the kits and you cant even contact anyone to get replacement parts before the initial warranty per their regulation is expired so we were very disappointed by our purchase....and the sad part is we don't want to ride our bikes because they are not finished and we are stuck because now we have to buy more parts even though we should not have to...

The kit was fun to put together the engine is pretty powerful just ran into a few issues here and there but overall its quality is pretty high just make sure before hand you have the necessary tools to put it together and make sure not to put the chain on to tight and also that the tensioner pulley is has the chain going straight on it and doesn't run or you will pop the master link chain off like I did but overall I would recommend this.

its not my first engine this is my 4th engine, if you know what youre doing and have the proper tools and little patient, you will have fun putting it together, it takes ME less than two hrs. yo put one togdther.

So many parts on this had to be replaced. It's a good thing my boyfriend is mechanically inclined because parts were leaking/breaking one after another. I wouldn't buy this again

Well worth the price. I only have gone 10.1 miles on it. It's a must to drill a hole through the chain adjuster, and the bike frame, then a #10 self tapper, or a screw and nut. It prevents the chain and chain adjuster from moving into the spokes. Check out You-tube for many videos on building it. I have a speedo/odometer for mileage. Great on gas. No smoke exhaust. 25 mph would be max speed for me. I love it.

Decent engine, daily inspections on parts, check if legal in your state and county, overall really fun great project and lots of looks

You need to be a wrench to operate any engine, clutch pin needs to be replaced often, main crank bolt was replaced with a grade 8 after I tapped it to something normal, I loved it but I was arrested and jailed in my county for operating on a sidewalk, it was impounded, and there I lay it to rest..
