This is a little off topic. I put a Marshall 0-15 psi liquid filled gauge on, but I found when the bike was started up cold the pressure would peg the gauge. Now the needle is bent I think and it won't register when the bike is hot. I've been looking for a 0-30 gauge but no luck so far.
I've been bidding on these oil pressure kits for a while and after reading this thread, I decided to do a search for "Marshall". I found a really nice 0-15 gauge for around $30, but look what it says about the gauges:
Attention: With all liquid filled gauges, you will get a false reading, or "zero" reading, on the gauge when the engine is running at operating temperature and the oil inside the gauge is hot. Fuel pressure readings must be taken when the gauge and engine temperatures are relatively cool. Over-pressurizing gauges can damage the gauge, causing the needle to become stuck above "zero." Damage caused by over-pressurizing is not covered under warranty; for warranty information, contact Marshall Instruments at 1-800-222-8476.
Zero reading when hot!!??
Isn't that when you want to read it? Am I missing something here? This is the same gauge that came with the last kit I bid on and was advertised as "With this kit the Driver can glance down and see the Engines Oil Pressure at all levels of the engines RPM's - The entire Bandwidth, properly used this Gauge can pay for itself many times over by saving your motor if your oil pressure drops or your pump fails."
Yea, as long as the oil isn't hot!
