MOPED ARMY

yeah, I checked on moparts.tk site and that malossi has a 27mm exhaust port, the most i've been able to open the standard sized one is 19mm, i've done three, stock, 65cc, and working on a 75cc.

I like the simonini porting schemes, and it is aluminium, and standard vespa pipes will fit. I'd be interested to try a vespa cylinder with a bigger exhaust port though, would need the pipe that fits it from moparts too, or make one..
