Oil Light

[rr109]

Hi, I own a 2005 S2R 800 and was recently went to an out of town trip with my friends on the way to our destination i had no problems but on our way back it rained hard. Going up the mountain my temp was reading 85 degrees, going back while it was raining, my temp indicator was LO'. Then suddenly the oil pressure indicator lightened up. It seems that the light turns off when its warmer. I was wondering whether there's a problem.

I use Motul synthetic oil. Hope you guys could help me out. Thanks.

Don't give it a second thought. This has happened to me
before, as well as a fellow with a MultiStrada. What's happening is
simple: water in getting into the oil pressure sender switch and shorting
it out. On my M750 the wiring runs vertically into it, giving water a clear
shot. If it bugs you, dab a little clear silicone sealer around the wire's
entrance. Or you could take the lazy man's way out: ignore it. The next day
after everything has dried out it'll be back to normal.

My 05 S2R has had an erratic oil light as well.

This water in the outer insulator on the wire sounds most reasonable.

Maybe some water in the engine oil becoming vapor once warmed up is adding to the problem.

Hi realgraverobber, thanks for the reply...everything's back to normal once the bike was completely dry...i guess ming was right...it was the water getting on the switch, but there wasn't any water in the engine oil, or else my engine would have knocked...again, thanks for the reply, i appreciate it
