Third run same as second run except stock can back on 75 MPH indicated.

Speedometer is off by about 8 percent high according to my GPS so top speed true is about 67 MPH at 8k RPM.

The Q sounds so much better now so I staying with the stock muffler.
I get no more than 37mph! Emphathy, pitty, symphathy... something, anything. Well, I won't give up finding parts... I'll try again tomorrow Saturday.
73mph on a 200cc and you're thinking about mods? Good job :D
