Call me Zoomer, aka Greg, I'm signing up from NZ to suss out these sohc thingies. I have a fleet of scooters and a GSX1100g atmo. Looking to add a cafe to the fold. More specifically a big noisy one that won't make me miss the 1100's oomph. I've been lurking around here for the last week and seems a lot esier to ask a couple of questions than persist with the search mission. There is so much good stuff that I get sidetracked.
