i was wondering if anyone made conical expansion chambers for pre 95 RS125? or can you retro fit one from post 95 RS125? If someone does make a conical expansion chamber for the pre 95's what is the company's name( do they have a website )? TIA
If by conical you mean cut and welded cone as opposed to hydro formed there are some small but not very meaning full differances. For the bike you speak you are goin gto have a hard time finding "new" except maybe Jolly Motto. Call Tommy Crawford. He makes a really good pipe for that scooter.
