TTMRC GY6 232cc Engine Package with Long Engine Case

DROWsports TTMRC GY6 232cc kit is the biggest motor you can build using a GY6 platform.   

“TTMRC 4 Valve 232cc Parts” has all the major components to assemble a complete GY6 232cc motor.  We recommend everything in this group as a minimum to convert a stock GY6 150 to a big bore 4 Valve 232cc GY6.  A water-cooled 67mm Big Bore Cylinder is also available as custom option.  Going water-cooled will require a custom radiator and water pump setup.

Parts Includes: TTMRC 4 Valve Head with roller rockers, 25mm intake and 22mm exhaust valves, TTMRC Cam Gear & Valve Cover, 67mm Cylinder with Forged Piston, Stroker Crankshaft with Head Studs and GY6 Long Crankcase. 

“GY6 150cc Donor Motor Hardware”  This group will include all the miscellaneous hardware that is needed to assemble the motor like nuts, bolts, air shroud, flywheel, starter, etc. We use all BRAND NEW parts & hardware in our DROWsports GY6 Donor Package and hand-pick upgrades on all the parts that needed to be upgraded.  DROWsports GY6 Donor Kit has over $150.00 in upgrades. (See additional info) 

“Engine Assemble Service” We at DROWsports take a lot of pride in our motor builds.  We measure and check everything from compression ratio to piston wall clearance before we assemble anything.  This is the only way to develop a powerful reliable motor.

“ DROW Head Porting Service” We have been developing our head porting for a few years now and made lots of improvements over the years.  We highly recommend our ported head as a must-do upgrade. (Can take an additional 1-2 weeks)

"Crankshaft Balancing & Truing Service"  We will balance the stroker crankshaft to the piston for better performance and reduce the harmonic of the crank. 

"Treatment and Coating" WPC is a metal treatment option that we do to most of our motor builds.  WPC Treatment will increase the wear life and reduce friction on all treated surfaces.  (will take an additional week to complete)

“Final Drive Gears” Depending on your riding needs we recommend anything from a  2.71:1 to a 2.25:1.  Most stock GY6 gear ratio is about 3.00:1 we recommend a 2.25:1 For most street use.  If you want more torque or acceleration, you can choose a 2.38:1 or 2.46:1. 

“Recommend Upgrades”  Performance parts upgrades, these parts will help you dial in the motor for your riding/racing needs.
