Picked up the speedmaster today complete with new exhausts and dyno tune.It sounds great, got that parrallel twin note and loud enough. The guys removed the AI but left the snorkel and were able to get 6 more hp and not run lean. However on the way home it cut out. Electrics fine, fuel fine , but was'nt recieving the fuel. Opened the fuel cap , put it back on and it started. Turns out there is a valve in the breather line and if its not completely vertical it shuts off and then no air flow. Any comments anyone?
