Default Re: HT Expansion chamber exhaust

I LOVE old Vaspas. And the biggest thing to do to these (or any) 2 stroke engine, is put an expansion chamber on it. There are some good and bad things about it. On the top end, you get some pretty good power (starting in the Mid Range). You might need to re-jet, though.
On the other hand, you get that two stroke dirt bike pop. It can get a little annoying, and piss off your neighbors, too. If you live in the boon-docks, you'll be ok. If you live (like me) in a sub-urban neighborhood, don't do it. Your neighbors will be PISSED, lol...
