YamahaUK Posted May 27, 2022 Share Posted May 27, 2022 I have an xs650, bigger oil pump, oil cooler, and remote filter. The Tacho cable is taken off the oil pump, so if the Tacho stops woking, the oil pump may not be working either. As we all know, the XS650 uses roller bearings, so the oil pressure / flow is low compared to engines with plain bearings. Has anyone got any idea what the Maximum and Minimum pressures should be, and does anyone know where I can get a mechanical pressure guage for this range?

Moderator drewpy Posted May 28, 2022 Moderator Share Posted May 28, 2022 can't help on the pressures, but if its zero, panic and stop the bike. As for a gauge, get one which has clear fluid in it or it'll explode with vibration. Just keep an eye on the Gauge and you'll soon get the pressures and know if it drops (all weather dependant too) My oil was like water in Andorra (45'C) and the oil light came on on tickover.
