The "MHR Team TUNED" cylinder is basically a 70cc "MHR Team 2" cylinder that was enhanced ("tuned") by Malossi. Malossi's engineers manually modified the MHR Team 2 cylinder by evening out small casting defects, decreasing thickness of exhaust port bridge and polishing the exhaust duct.
It comes with a 13mm piston (17mm crankshaft for 13x17x17.5mm small end bearing, 85mm connecting rod). The modification to the exhaust port bridge leads to a larger exhaust surface area, the polished exhaust duct prevents sooting, both resulting in improved flow - and improved performance.
In combination with the right components (28mm carburetor, digital ignition and "Hyper Racing" exhaust, the MHR Team TUNED can reach more than 23hp!
NOTE: you'll have to mill the crankcase to make room for the cylinder base (see manual for detailed instructions).
13mm piston pin.
Can only be used with 85mm connecting rod!
