Can anyone confirm that the oil warning light works on the Oil LEVEL, as opposed to the oil PRESSURE? I read somewhere that this was normal on Yamahas but can't find evidence to support this.
talking about light warnings, my "80km/h" red light doesnt come on. i have a 2kr. how do i check the connection? how do i check the bulb? might sound gay, but id like that light to come on cause the M5 tunnel is 80 and im on there atleast acouple of times a day. thanks
haha, true. but i happen to know where they are so i try to slow down there.. but i stil wanna know how to fix..
It's definitely a level. For months my oil light didn't come on, I went up a steep hill recently and the light came on lol. Never had it come on since.
HANGON, How can it be a level sensor? (from memory) if you ever have the pleasure of pulling off the sump you'll find a little copper coloured thing bolted to the side (later morels) or the bottom (earlier) which has a feed i think pre filter (might be post) but oil is fed through it which pushes a bit which closes a loop which turns off the oil light how else do you explain your light coming on when you have the ignition on but not cranking? If you are going up a hill, particularly a large one, your pickup may not be immersed in oil therefore not drawing oil and hence creating pressure..
i've had the oil light come on a few times recently after hard riding and after getting home find the oil level is OK. That says to me that its more likely a pressure sensor (as brad reckons) - when the oil gets real hot it gets more runny (that's a technical term) and so doesn't create as much pressure - this causes the light to go on. Of course i can't back this up with any facts.
The sensor is located in the front of the engine and on the right side if I remember correctly. With all of the larger bore engines that I have seen and heard about torn down on the Brotherhood, I'm going to have to side with them on their knowledge of what is going on in there.
Speaking of oil lights. Turns out my clutch/gearbox related issues were oil related. My oil light has failed and my oil was dry... Now when I change gears I hear a big "CLUNK".... Anyone have an idea what that is? So pissed.... Just goes to show, don't trust your oil light. Check it manually.
I also beleive it is a level sensor on the fzr. I was able to park my bike at the bottom of a steep driveway, check the oil, and all is fine (and no light). Roll it part way up the driveway and voila - the oil light comes on. Wouldn't happen if it was pressure sensor. The clunk could just be your bike not liking the oil that you put into it. If I put regular oil in my current bike I get clunks, if I put in part-synthetic or fully synthetic it is reasonably smooth (as smooth as I have felt a yamaha gearbox that is).
Lots of oil in the sump is not much use unless you have oil pressure in the system. I would hope it is a pressure sensor..............
It's not an oil level sensor, it's a pressure sensor. If your bikes oil light is coming on, that means the oil pump is sucking in air and as air is compressable, the oil pressure goes down so the light comes on. Think about what a brake does when you get air in the brake line, you loose pressure. In an engine, loosing pressure is bad, this means that the bearings aren't getting enough oil. Loosing pressure in the brake system is also bad, very bad. <!-- s --><img src="{SMILIES_PATH}/icon_smile.gif" alt="" title="Smile" /><!-- s -->
Doubles as a Charge light? I'm thinking it doubles as a charge light, so it also comes on when your bike is not charging and goes out if it starts charging again.
OK this is how it is: 2KR has an oil LEVEL sensor 3LN-1 has an oil LEVEL sensor 3LN-3 has an oil PREASURE sensor If it turns on.. while riding pull off to the side of the road turn the engine off... spend two minutes thinking if there was some thing not normal in your riding... like an EXTREAMYL steap hill... or when was the last time you checked the oil level?? Than check the oil level (make soure the bike is on a level surface)... if there is NO oil in the window you could be in trobble...
LOL, You'd know that, TBone, after fixing up my 3LN-3's oil light! You might also want to point out that you check the oil level with the bike off, otherwise you'll get a verrry incorrect reading.
I still think that you are wrong on the 3LN-3 having an oil pressure switch. I went through my Haynes manual which covers FZR 600, 750, and 1000's from '87-'96, and my 1000 Factory service manual, which covers FZR1000 from '87-'95 and both refer to the oil level sensor. I doubt that Yamaha would change 1 engine from a level sensor to a pressure sensor.
Interesting... the MAJOR difference b/w the two is their location.. the LEVEL sensor is always underneeth the bike while the PREASURE sensor can be located preaty much any where on the engine (FZR250 has it on the side next to the oil filter)...
