Value and Quality!
I purchased this for the Mega Moto 80 bike I’m building. I needed you use GPS small block adapter plate to get it to mount properly, but it fits nicely. Upon installing it, I noticed the air cleaner housing was damaged. GPS sent me a replacement very quickly. I finally got it installed and it runs very well in this bike. I feel the quality is as good or better than the 79cc Predator and has the same power. Add in the fact that it’s less expensive and it’s really a strong value!

Awesome value for the...
This is a no-nonsense 3-horse gasoline engine that I just received via UPS. Has a 5/8" output shaft. I had a 5/8" bore pulley lying around and can see that it will be a tight fit. No problem. That's what emery cloth is for. Easy to start. Guessing the compression ratio is probably about 7:1. Move the choke lever to "start" and the fuel shutoff arm to point downwards. I added half a quart of 10W-30, and that seemed like it was right to the top of the dipstick. Placed the engine on the ground, pulled it a few times (probably to prime the carburetor), and with the choke closed I could tell it was wanting to start. Stumbled a little. OK, open the choke and try again. It started right up. The throttle is such that it starts up at idle speed. Moving the lever revs it up. Letting go of the lever makes it drop back to idle. There is a set screw that looks like it can raise the RPM that it defaults to. I just wanted to start it up and give it a proper welcome to the family. Watch the enclosed video. I know this engine is likely intended for small go-karts, I intend to make a 1500W generator out of it. The noise it produces would not be obnoxious in a campsite setting. Just throw some expanded foam board around it and it would be fine. Shipping to GA was $22. Get you one! :)

Clean little...
Bought it to replace a 97cc engine on an old dirt bug, really clean fit and compatible with aftermarket parts. Gets me going and im about 250 lbs. Perfect for the younger crowd, very solid build.

Nice OEM engine for smaller mini...
Original package was damaged and stock air filter housing was cracked - wasn't planning to use the air filter housing anyway. Packaging was solid though. No idea how it was cracked. This engine does have a slightly larger stroke than the 79cc Predator and in stock form gives more noticeable power. I was hoping this would be a reincarnation of the 99cc Predator that isn't sold any longer. It has the plastic or nylon cam, longer push rods and different crank. I didn't measure the lobes on the cam. The crank has alot of excessive left/right play with side cover and flywheel removed - I observed at least 1/4". Many parts are interchangeable with the 79cc Predator but not everything. We already had a Predator with PZ19 carb, intake manifold, billet flywheel, and 18lbs springs to compare it to on a CT100U Coleman mini bike. After removing the governor, I was hoping to add a billet flywheel from ARC but the taper on the crank seemed slightly different than that of a 79cc predator we have. I was able to make it work but could never get the engine to run right (no idle, constantly surged and died, no idle) with 18 lbs springs, manifold for 19mm carburetor and PZ19 flat slide carb. Maybe too much timing from the flywheel? I tried resetting the gap on the flywheel, spark plug gap and valves many times using specs from severals sources to include the manufacturer. I re-jetted the carb as well. No matter what I did, I couldn't keep it running with the billet flywheel. I generally can tune just about any build with time. I abandoned the build and returned it to stock form but kept 18lb springs, manifold and flat slide carb and its running fine. Does have the same weak flywheel as the predator. Was an experiment and for the price you can't beat it.

It came welded?
Im not sure why the motor showed up with the set screw tack welded? Its a great little motor I just would have liked the option of not welded before arrival.

excellent...
Surprisingly nice, solid, well-made engine that arrived very quickly, and well packaged. Used to replace a Briggs 3 hp on a McLane lawn edger. Required raising the engine off the frame 1 1/2" with spacers so that the the air cleaner would clear the rear tire. Engine requires a throttle cable-42" for McLane. Needs a kill switch not supplied, but is pre-wired and with a plastic plug on the flywheel cover for a snap-in 2-wire kill switch-about $10. Other wire goes to ground. Started easily, and easy to pull. Rope pulls straight up, unlike the Predator which pulls forward (inconvenient). Phenomenal value. Good communication and follow through by Go Power Sports. Don't hesitate to purchase.

Dao
Found out last momment after i deleted governor that the engines cam gear was stripped out the box.i hope the manufacturer goes to metal cam gear for this very reason.i found a fix for it thanks to a reliable knowledgeable freind now i have to wait for my fix

Great Power for such a small...
I used this engine on an old doodlebug frame that used to have the 97cc flathead on it. The engine is great for my 11yo nephew, and it will even pull me (170lbs) around a field without much of a struggle.
