Yamaha oil level switches???

[a j]

I've had a reoccuring problem with my R6 with the oil "pressure" light coming on. Hopeing is would be the switch i popped into Frontiers (WImbledon) to get a new switch. The parts chap said that they had one at £50!! But in his experiance they had never replaced one but they were a "level" switch as opposed to one that works off pressure. Working in a plant machinery industry and been involved with cars and bikes for ages i've never heard of just level switches, has anyone else? Seem bloody stupid, what happens if you loose pressure with ample oil in the sump?

So anyway now the oil light comes on when the oil is half way down the distick

I've got an R1 workshop manual in front of me. It's a pressure sender you're probably after. The guy from Frontiers is talking out of his exhaust. How can a bike have a level switch when they often don't have baffled sumps and may have big surge problems under accel and braking?! They don't run dry sumnps either! I don't think the sender unit is wired into the CDI though. If the bike won't start, you've got something else wrong (like the side stand down or something....). If in doubt, whip out the pressure sender unit and plug in a workshop oil presure guage - as long as you've got decent pressure, and sufficient oil, I'd ignore the light. If you need to sell it, take the LED out with a pin.....

Most Yams are like that, my Exup is the same, light came on on the motorway after buying it, was not pleased, thought it was knackered, only needed 1/4 litre of oil to top it up.

Cheers chaps - topped up with oil and seems fine. Seems its a yam specific problem.

Fergus - no problems with it starting, just when i hammer it / and or stop quickly and its half way down the dip stick. IMHO very poor design.
