Stage 2: 301cc Hemi Predator / GX240-GX270 Performance Kit

Stage 2: 301cc Hemi Predator / GX240-GX270 Performance Kit

This is an awesome upgrade kit for the 301cc. Very easy to install, has all the bits you need and results in a significant power upgrade. Not sure exactly how much because I don’t have a dyno, but I’m gonna guess that it nearly doubled the output on my gokart. I should point out that I paired with a Mikuni 28mm flat slide carb, which obviously had an impact too. Either way, well worth the investment! Very happy with my purchase!

Stage 2: 301cc Hemi Predator / GX240-GX270 Performance Kit

I'm in the process of building this motor for a friend and, have done everything as directed, waiting for the carb and manifold and pipe. It should be a hot little motor. It's going in a Baja 200 mini and will be a hang on tight build no doubt.

Good stuff

I haven’t purchased the Predator engine but I bet if you added this kit it would make 50 horsepower and go 150mph on the track with a small mini bike. Hang on!

don't know how much faster this makes it because I haven't received my valve spring compressor tool yet.

This performance kit is AMAZING!! Combined with the 13hp carburetor, jet kit, air kit, and tuned pipe my 8hp predator is purring like a kitten!!! Straight out of the box my motor was putting out 3500 rpm, now it is at a whopping 6240 on the bench!!! Cant wait to get it on the track for a spin. I've never been disappointed with anything I've purchased from Go Power Sports, they have always delivered on time and are great to work with on line or in person. Keep doing what you do!!!!

I HAVEN'T FINISHED ASSEMBY YET, GETTIN ANXIOUS.
