Tried to start bike with kill switch off, now has FI light

HI everyone.

I just did the R6 throttle tube mod. I had to go all the way to the throttle bodies to get the slack I needed for the cable.

I finished, and everything was going smooth until I went to test start the bike. It wouldn't start. I assumed that it just had no fuel in the fuel rail since I drained it and just held the start button for about 5 seconds, stopped for a few seconds then tried again for 5 more seconds. So 10 seconds of just trying to start the bike. Finally I realized that the stupid kill switch was off. I flipped it on and the bike started right up. *phew* I let the bike run for about 20 seconds and then I noticed the FI light was on. I turned the bike off checked all my connections then went to turn it back on and the bike was slow to turn over, but it did.

But it was sounding very slowly like it didn't want to idle at all (Unlike before I turned it off it was idling decently okay..) I turned it off thinking maybe I was causing damage by leaving it on.

I didn't try and start it again after that, figured I should stop and take a breather before I do more harm than good.

Now I am wondering if I flooded the cylinder from trying to start it for 10 seconds. It is about 40 degrees outside. When I turned the bike off I noticed a little "smoke" (or steam, idk, unburnt fuel perhaps?) coming out of the exhaust pipe. It was a very little amount that went away within seconds.

I was really careful the entire process and took notes of all the plugs I undid and I went through and checked all my connections already.

Any advice? I'm thinking I'm just going to let it sit for about 30 minutes then try and start again and see what happens...

Well, I went ahead and tried starting it again. She started and after idling for about 3 seconds the FI light came back on. I could smell gas and a decent amount of white smoke was coming out of the exhaust. I let it idle for about 90 seconds before shutting her off... I don't get it. I'm going to just go take everything apart one more time and make sure everything's connected..

I guess it's worth noting that I cleaned the air filter. But I followed the directions and made sure not to over oil it, and to only oil the side that faces out.

Is there any connectors that would really screw up the EFI? I had my computer plugged into the bike and I was getting a throttle percentage so I know it's not the TPS. I do have a power commander and Auto Tune, I noticed the auto tune was blinking green, not sure what that means.

Figured it out! There's a very tiny stupid rubber hose on the bottom of the airbox near the throttle cables that I never saw. Also there wasn't even a hose clamp on it. So I went ahead and added one reconnected it and put everything back together and she is now running perfect.

Here I circled the hose and the part it connects to.

that's the map (manifold absolute pressure) sensor. a very very important little device.


it measures how much vacuum is behind the throttle plates and helps your bike decide how much fuel to provide to the engine. if it's reading 1 atosphere (its disconnected state) then it's obviously out of range, as with the throttle closed you should have plenty of vacuum

What year model is this?

Last time I tore my '03 down I don't remember seeing that little hose. IIRC the MAP sensor is on the right next to the air box if you're looking at is from the seating position. It may have the hose, but has been ages since I've stripped mine.

Started reading your post and thought "small black MAP sensor hose" and see you got it. That one is missed a lot because it's easily missed when you take the air box off and it usually slips off without people even noticing or realizing it's there.

Glad you got it fixed.

The R6 throttle tube is a nice mod; it's a great throttle travel and should be that way from the factory. I've run a 1/4 turn and on the street it's just too twitchy to ride smoothly at times.

Jeeezz... Yeah, I am very surprised honda didn't put a hose clamp on it from the factory... seems too important to just have nothing... Luckily I had a small clamp laying around and I was able to tighten it on.

Thanks lol.

I had debated it for months because I knew I didn't want to go down to the throttle bodies. Finally bit the bullet and just did it. It only takes about one hour to get down to the throttle bodies when you know what you are doing (unlike me who didn't and it ended up being an almost all day afair because I was troubleshooting so much lol)

I rode it down the street just to make sure everything was okay on the bike before I started putting the plastics back on and everything seemed fine. I had no grip on my throttle because I needed some superglue so I haven't really gotten the chance to properly feel the throttle. but WOT feels 1000X times better.

I can't wait to take it to the twisties once the weather warms up.
