Yeah the vibration between 1/4-1/2 throttle was pretty bad. The vibration has gone down a bit since I've been breaking it in. This motor definitely has more torque though as I can get some nice drifts going in the gravel parking lot beside my house that the Subaru motor couldn't do very well...
I'm not really impressed with this predator. It vibrates my kart to the point where it's not fun driving. The Subaru motor was a little faster and didn't vibrate nearly as much, but on the plus side, gas doesn't leak out of the carb on this motor.
Bought a 212cc predator today and installed it. Everything from the old motor swapped right over. Just need to wire up the front kill switch and adjust the brakes and she'll be back in action. Please excuse all the dirt...
Mine was missing a part or two also. My carb is leaking now after a second cleaning and the threads are stripped to the bowl, but my kart drives now with the new belt. I'm planning on swapping a predator 212cc on soon.
Scrubbed the rear swing arm down, then my kids wanted to drive in the go kart so I pushed it while my oldest one steered.

Slapped the motor back on along with shock. Notice I painted a few...
Did some more work yesterday. Rented a puller to separate the driven clutch then sanded the rust off, wire wheeled and polished. Put the spring in the wrong way the first time I put it back together, so had to pull it back apart and redo. Set the spring at #3 for off road...
New to this whole go kart thing. I've mostly worked on cars and motorcycles.
I took this picture the day before picking it up. The seller stated that it only needed a drive belt, that was false. I checked it over the best an amateur like me could and found that the cvt pulleys needed replaced...
New guy to go-karts here. Just bought my first one today. It's a Fox Vortex with a 169cc Subaru engine. Needs some TLC but the motor runs and the frame is in good shape. I'm hoping to have it drivable in the next week or two.
