bike idling then shutting off

well i have had a recent problem with my 98 900rr...i turn it on and once its watmed up when it idles its really rough...then when i thought that was the only problem i noticed when i am riding and im downshifting coming to a stop sometimes the bike just shuts off...i can press the start button and it comes right back on but still when i ride on streets/highways its fine doesnt sputter or anythign so its only when stopped (idling) and coming to a stop

any insight?

i recently had it sit in the rain and today i took the tank and stuff off and the sub filter was really wet could that be the problem? i rinsed it and its airing now but im gonna buy a K&N filter for the regular and sub filter just to rule that out.

also coudl it be the spark plugs? and if so how do i go about getting to them?

HELP!

also the oil window where you see how much oil is in the bike...can i just pour some oil in there to refill (not change) just to assure that there is sufficient amounts of oil?

Oil... pull the bike up level and look in the sight glass.. if its between the hashes you're good!

Wet filter... that will cause some issues for sure!

Spark plugs... under your gas tank about 8" into the heads you'll find your spark - o - madness. Pull one, hook it back up to the wire.. place the end of the plug against the head and hit the starter... see if it sparks!

Just a note. if a plug wasnt firing, it would cause a rough running issue throughout the rpm range, not just at idle.

ls1ssws6, when youre off throttle at speed, does it decelerate harder than usual?

I thought we already went over how to change out plugs?

just a thought

so it happened after a rain? sounds like you got some water down by the plugs, and having 4 cylinders is masking the problem at speed. Take some compressed air, pop the wire off the plug, and blow down by the plug... alot. Do the same to the plug wires and reattach with some dielectric grease shot in the spark plug boot. Give that a try and call me in the morning.
