172cc GY6 Drop In Crate Engine
172cc GY6 Drop In Crate Engine
Are you looking for big drop in power? This GY6 171cc or as others call it, a 172cc Drop in crate engine is the set up! We utilize Jeff Pfeiffer out of Washington (aka @mayor_of_wa_riders) to build all of our drop in ready motors. We put together the two most common builds into two 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 an exposed belt or not, and finally, choose rear disc brakes or standard drum brakes.
All kits will come with a 28mm pro carburetor and short wheel axle. You will need to select an exhaust system and stator to complete the build (stator not included), 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 you’re good! After placing this order, expect 2-3 weeks lead time as we build this motor for you. You will have the option to change specs based on your riding style, and also customize any cosmetic changes.
These options include:
- High altitude piston
- Case brace color
- Brake caliper colors
- Carburetor size.
You are gonna love it!
