    1996 Suzuki DT65. SEIZED!

    35hp crankcase pressure

    I've been troubleshooting low fuel pressure from the fuel pump and after changing it for a known good pump, I'm now suspecting the crankcase pressure. Anyone out there know how much pressure to expect from the crankcase hole which supplies the pump? Right now I'm only getting a slight puff of...
