After much discussion in the AF1 Racing forums, a moderator has agreed with me that the Aprilia SR50 is a good platform to test a new propane configuration.
The throttle body / air neck will receive propane vapor during WOT (Wide Open Throttle), top-speed operation. At lower ranges, either of throttle or speed, the existing air/fuel injector will carry a regulated vapor/liquid flow directly into the cylinder while all ports are closed. We hope to preserve economy and obtain performance in this way.
Is there a 5 pound propane bottle that can be fitted with a short vapor dip tube and a long liquid dip tube, or a valve body that can be installed into a standard 5 pound propane bottle?
