This is old but...
I got mine to almost 90mph with the pipe, carb kit, cam timing kit, and air filter. It was allot quicker too. The deal with the 170cc kit fell through as MZ decided to pull their loaner project 125Sm from Poweroll before the company finished the project. The prototype was a rocket for a 170 so Poweroll said. Unfortunate...the 150cc kit from MZ was and is expensive at $449.00 and adds only 2hp but more useable torque so may be worth it.
