Insane performance right out of the box. If you're tired of 5-6 hp and want a real adult motor for a mini bike this is the one!
Been buying performance parts for my clone 196cc, sometimes ordering the wrong stuff, just to make it fast and reliable. Then came across this engine from GPS and WOW, should have bought the from the start, would have saved me a lot of time, money, and headaches. This engine is fine-tuned machine, power is still surprising to me every time I take it for a ride. I'll buy another one just to start another project.
Great power band for the money, combined with the gps juggernaut pulley I’ve been able to do wheelies on a Mb200.
Looks awesome can’t wait to run it. Does anyone have break in recommendations for this motor?
this motor is amazing! I'd like to fit the venom roller rockers on next. clear valve cover obviously!
It looks cool. I’m still waiting for the missing air filter that should have been included. As soon as it arrives I’ll get her started.
Ran through plenty 212s and wanted something faster and better built. Fought with the price until my son brought his. Got on and felt the difference! This motor is worth it. Brought me one as well. Also, special thanks to Jeff. Gives the his best efforts every time!
Decided to buy it and I'm glad I did. Runs great fired right up. Big improvement on my mb200 trailmaster. Hopefully have a video up of it soon on the tube.
The Tillotson 225 from Go PowerSports was the perfect ingredient to bolt onto my Manco BigCat. I never feel that I am lacking power and with it mated to Jugg-a-Vert it’s allowed to rev to the higher RPMs without a problem. If they offered larger I would order them as well. Great engineering.
