I've got this piston and I'm running it on an uncasematched Puch Airsal 44mm Piston Port Kit on an e50. I'm seeing north of 10,000rpms with this piston, a 15mm bing with stock airbox, tecno bullet pipe, the sport touring head and 16x45 gearing.
It is 100% identical to the 2 ring piston with the exception that it only has 1 groove for a ring instead of two.
