Are you looking for big drop in power? This GY6 171cc Drop in crate engine is the set up! We utilize Jeff Pfeiffer out of Washington (aka #mayor_of_washingtion) to build all of our drop in ready motors. We put together the two most common builds into 2 options for you to choose from. We give you the option for a CVT transmission kit, choose our Ultimate CVT kit or our Standard Performance CVT kit, choose a forged piston or cast piston, choose exposed belt or not, and finally choose rear disk brakes or standard drum brakes. All kits will come with a carburetor and short wheel axle. You will need to select a exhaust system and stator (comes with wiring harness)to complete the build, and depending on your engine set up, you may need a carburetor clocking flange. 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 to hard. Change the oil at 100 miles and your good! After placing this order expect 2-3 weeks lead time as we build this motor for you. Your gonna love it!
