The arrow always goes in the direction of flow .

Thats what i thought. Im running a completely different kit now but the piston is pointed down towards the exhaust port. I guess someone threw the stock piston in the motor upside down.

My next thought is drop the jetting down to like a 74 main (only 2 sizes up to make up for the extra 10cc). I was just wondering if there could be differences in the factory time / curve between the QT50 & the MJ50. I might swap back to the OG MJ50 stator & CDI box if the jetting yeilds no results.
