I have a completely stock 1977 Garelli SSXL. Cruises about 19mph. I have a performance pipe for it as well, not mounted up and sold separately. I honestly don't know the brand, but I will check it out and try and post something up here later.
I also have a 1979 Honda Hobbit. It is a PA50-I. It has a II ramp plate on it, as well as a drilled out stock PA50-I carb with an 86 jet as of now. It has a DR kit with boysen reeds. Pretty stock looking otherwise. It also has a Proma Circuit Pipe without a baffle right now. It has been put to the wayside for a bit, but still runs strong as of right now.
I live in downtown GR, so if you are here for the rally, feel free to give me a text or a call with an offer, or if you wanna come by and take a look.
