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.
I’ve built two stage 2 predator engines which including the motor and parts are coming close to the precise of this engine. But performance the 225 completely blows them out of the water. Built extremely well and holds up to whatever you throw at it and still maintaining reliability. Absolutely worth the money
Awesome power and great torque for the money,I have it on a dirt kart and works great
