ZTMoto Phantom 85 V3 - Complete 52mm Bore 2 Stroke Motorized Bicycle Engine Kit - True 85cc Bike Motor 36 Tooth

Set up the motor on a Huffy Cranbrook with Mags and a 32T rear cnc sprocket. Got it up to 53 mph on a flat street and cruises nicely at 35-40mph all day. Switched out the carb for an aftermarket “racing” carb but need to change the jetting due to running rich at higher rpm and speeds. Night and day difference in powers from the china doll I was running before.

When you put together the top end pay close attention to the piston and piston rings. I must have had hairline fractures in the piston because on both of them the window blew out on them. Scared the inside wall of the jug. !!!!!!!!-BUT- !!!!!!!!while it was running its by far the best engine I have ran so far. I bought 2 right off the bat because of mishaps. The company that i bought them from was very nice and generous. They took care of me. Went through the steps and it all worked out. Not really sure that it was worth the price tag but.......... I will leave a better review when I get to take a long ride.

I love the way it looks it looks great on the bike the only problem I have is I can't get one part for it to actually attach the rear wheel other than that it was pretty easy to put together I wish it came assembled but I understand why it doesn't it is awesome looks great I can't wait to ride it this summer

This engine is totally worth it to set up when you have some spare time and if you do buy it. It’s totally worth it thanks whoever made this is a genius.

Earlier I commented about accidentally ordering wrong chain size. There’s no screws that fit from the carburetor into the engine. Very bad problem honestly tried to tape, just ended up flooding the carburetor.

This engine is hit or miss when it hits its amazing but it misses way to much making it a gamble to buy fortunately custom service is amazing and the warranty they offer is incredible they’ll replace any issues without hassle

The media could not be loaded.  think i should have gotten a new replaced exhaust since i wrote and no reply ,after 3 days my exhaust cracked around the weld seem connecting the expansion chamber and neck and could never get the carburetor tuned right it was starving for fuel when i ran it wide open but other than that it was something that i liked to run around in town on cause i liked to show it off

When I got the motor it had a big air leak in the intake so I made a gasket and now it runs good!!!
