Derestricting PX150
Posted: Fri May 12, 2023 8:51 pm
I have a PX150 Anniversary which is restricted to 58mph and need it to go faster as using it for work on dual carriageways. I'm going to get a Sip 2 exhaust and sort the air filter. But what is the best way so blank off the pipe that currently takes unburnt gases back into the cylinder?
