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

I recently purchased and installed this bike engine kit, and despite a few hiccups, I'm ultimately very pleased with the results. The engine itself sounds fantastic. Performance wise, I've had little to no issues since installation.The installation, however, was a bit of an adventure. While the engine itself is relatively straightforward, the included guide book is completely useless. Every comment/review I found recommended skipping it entirely, and I wholeheartedly agree. Save yourself the frustration and head straight to YouTube for a visual walkthrough.A couple of specific installation notes:• Handlebar Hole: The instructions suggest drilling a hole for the throttle cable. I used a center punch, as I do not have a drill. It gave me a clean, precise hole.• Chain Issues: Be warned – the chain that comes with this kit is larger than standard bike chains. My standard chain breaker was completely ineffective. I ended up using my center punch and the spark plug remover from the included tool kit to remove the necessary links. It was a bit of a workaround, but it got the job done.Despite these installation challenges, I'm very happy with the engine. It's powerful, sounds great, and has been reliable. If you're comfortable with a bit of DIY and willing to rely on online resources, this engine is a great value.Tools I used:• Standard Pliers - for nuts• Needle Nose Pliers - for master link• Ratchet with Sockets - for nuts• Phillips Screwdriver - for screws• Center Punch + Hammer - for hole + chain• Allen Keys - for bolts• Tin Snippers - for rubber piece & zip ties• Zip ties - for securing cables• Electrical Tape - for protecting wires*I run standard gasoline + 2 cycle engine oil.

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.

Worked great for several months of hard riding I think clutch is gone because I rode it when brakes went out after first week! Does 35 + for certain clocked it stock. I'm ordering extra clutch pads and going to test it after replacement to see how far I can get. May but another and get different computer to clock things though that computer never got attached right when I slapped it together.

The media could not be loaded. amazing engine runs like a beautie after building it fired up almost first try, the assembly was pretty easy and it fits almost any bike with a v frame the best part is to install the engine and the worst it the sprocket be careful with the center of the sprocket and the wheel. so it came almost undamaged exept the tank, it was bent but had mo leaks and the box looked deformed I bought a 32 tooth sprocket and I get speeds about to 55 km/h so like 30-35 mph about mixing the fuel and the oil is up to you just add about 5 to 10 caps of oil into there and will run good, about the miles per gallon it's really small I go around 2 weeks at one tank and the tank is pretty big. about the speedometer it worked for like 30 minutes and died and new battery dosent help. I got a problem because of my fault I burned the clutch because I was trying to start from standing without pedaling so I had to buy a new one so I will warn yall that the clutch is not that strong so if your bike is running you will have to pedal first and then let of clutch and the give gas. the choke does not work it only starts on open so I don't use it. the clutch lever is not that good because the lock on it doesn't hold it good enough and it could slip. the chain will loosen a lot so you will need to tighten the tensinor from time to time.breakin in the engine should last about 200 miles.the fuel filter will turn bad in a couple of days and you should probably buy a better one from autoparts so it won't leak. SOME TIPS: when you are assembling your bike and don't know how to get the chain through the engine drive sprocket, just grab a hart tool and the right socket and spin it clock wise and you will get your chain trough when starting your bike you should get some speed give it full throttle and it will start in a couple of tries and you will have to tighten the bolt at the left of the carburator for good running pase. if your bike won't start check your carburator if it has leaks or if the gas is working the the fuel is coming in to the carburator, check the spark plug to check if you have spark you will have to sit on you bike pedal touch your spark with your finger int if is slightly hits you the it means you have spark if not check the wiring and check if it's clipped on to the clam if all of that dosent hel that you should try another spark plug. that's it thanks for reading.
