    RPM Loss

    My 1996 Yamaha 250's are acting up. More specifically the STBD side will on pull 4800 RPM's while I get 5400 on the PORT side. Also I noticed on the fuel mgmt system that STBD at cruise is sucking 17gph while the port side is 10gph. STBD side starts and idles smoothly. Any suggestions ?
