Two Stroke Motocross got together with Cycle Playground and put together a power plant for the SX.

Michael Soudas at Cycle Playground put his touches on the SX motor.  Starting off with an engine blueprint, head mod for combustion efficiency and all around power gains on pump fuel. Cylinder porting for increased flow and efficiency. The cases were matched and stuffed and case to cylinder match. The exhaust port and power valve were modified for increased flow and higher rpm’s and finished off with the carb oval bored to 39mm for increased mid range and top end.

This project came down to the last-minute, like they all seem to. Two Stroke Motocross got together with Cycle Playground and put together a power plant for the SX.

Michael Soudas at Cycle Playground put his touches on the SX motor.  Starting off with an engine blueprint, head mod for combustion efficiency and all around power gains on pump fuel. Cylinder porting for increased flow and efficiency. The cases were matched and stuffed and case to cylinder match. The exhaust port and power valve were modified for increased flow and higher rpm’s and finished off with the carb oval bored to 39mm for increased mid range and top end.

The bike was completely torn down so the frame could be powder coated KTM orange. While the bike was apart the motor went to Cycle Playground for a work-over and the suspension went out to Bumpstiks to keep the power to the ground. The suspension came back last night. They got it all back together just in time to head to Virginia Motorsports Park for this weekend’s MAMA race. Want to see it in action? TSM will be out there filming the racing action tomorrow, so stay tuned for video’s and race results.
