just bought a 98 gsxr 750 last week. did an oil change today, and now its telling me to check the oil and it wasn't before...what the hell? i put in 2600ml like it calls for(oil message came on) then i noticed on the sight glass i could add more(because of the oil filter i assume?) so i added a bit more but the message is still on?...i plan on getting the repair manual asap but until then some info would be sweet.

I'm assuming you also started it up and cycled the oil through it before checking it again?

The bike takes 3 liters....so ya your a bit low and my guess is you never actually checked the level, the started the bike, waitied for the filter to fill up cycling the oil, then shut it down, waited a minute then re checked the level ....did you?

I hate pointing out obvious stuff, but is the bike running while the light is on? because it will be on while the bike is 'on' but not in run.

Also it might be a stored message. Try unplugging your battery and pulling the brake trigger for a few seconds, then hook up the battery and see if the light comes on when you run the bike.

Cheers.

a tip for the future, fill up the filter with oil before you put it back on, this way you get the right level sooner and your engine doesn't have to cycle as long without oil after the change.

The light will come on if there is no or low pressure. If it is on with the bike running then either the bike is very low on oil, the oil pump isnt working, or the sending unit lost its wire. first check is to look at the sending unit and see if the wire to it has a good connection, then pull the wire off and with the key and light on ground it to see if the circuit works, by grounding it the ligh should go out. If that works remove the pressure switch and either just replace it or with an air line do a bench test on it.

Okay, newbie question. Are you supposed to check oil level when the engine is warm? (e.g. 5-10 minutes after a ride) Will oil level show higher if you measure it when it's cold?

just like your car, best time to check is when it's cold. bike should be on level ground and if possible have someone hold the bike straight up and down (not leaning on the kickstand) while you check the oil. if the bike is tilted even slightly it can throw the reading off and show as okay while it may actually be low

Like most fluids oil will expand slightly when hot compared to ambient temps, however not really enough to be important to you. As long as you are around the full mark all will be good, I look at mine hot and cold and don't really notice a difference.

my BMW manual says check the oil when engine is fully HOT (for my specific bike, that is)

Generally I feel either hot or cold is fine, as long as you do not check the level IMMEDIATELY after shutting down: give it a minute or so for most of the oil to drain down back to the sump.

But that is just the OCD in me: probably does not make a huge difference: reading will be probably be close enough either way...

Actually, no.
Most of it will pour back out and make a mess as you try and put it back on.
put it on empty, and just rev it up once to about 3-4000 RPM as soon as it starts, and BINGO, lights goes out right away. Maybe not his problem, but the pump will fill that filter in a hurry given the right revs.

i read it on the internet so it must be true.

not full to the brim, just enough to soak the filter - and be quick like a bunny so you don't spill any.

Good advice that would work on a filter which mounts vertically with its closed end at the bottom. I've been doing this for years and the difference in "dry time" is noticeable.

The filter on my bike mounts horizontally, and I have always primed it with new oil before installation. I don't fill it to the brim, about 2/3 full does the trick and it doesn't spill a drop when I spin it on. Some oil in the filter is better than bone dry.
