Perhaps a bit beyond the scope of the average home tuner...has anyone ever considered a variable exhaust port on one of these engines?
The first time I sawit was back in the 80s on the yamaha twin RZ250 I think.
Just felt like mentioning a few more two stroke hot ups beyond porting and the more common go fast tricks.
Cheers
