190cc GY6 Drop In Crate Engine

Are you looking for a monster 190cc GY6 engine for your Honda Ruckus, Genuine Buddy, go kart, or custom scooter? No prob! We build performance motors. We will start the build with brand new engine cases bored out to fit the massive 63mm cylinder. We will then install a performance stroker crankshaft with crank bearings into the engine case. With both the stroker crank shaft and 63mm big bore kit, this makes your GY6(A) a 187.97cc. We will then complete the build with a 63mm cylinder head, a 28mm carburetor with a larger intake manifold, a high output starter and starter clutch, a performance CVT transmission kit, a new set of gaskets, and finally a pod style air filter.

The carburetor jetting and exhaust system will be up to you. Jetting varies with  different altitudes through out the United States. It will need to be tuned to your altitude. Remember there is no warranty on performance products, so it is important to break in the engine properly. Vary the engine RPMs while riding, not pushing the motor too hard. Change the oil at 100 miles, and you are good! After placing this order, expect 2-3 weeks lead time as we build this motor for you.

You are gonna love it!
