Got to work today morning on the bike and everything was fine. As I was heading out for lunch, the ignition didn't fire up at the first attempt (happens rarely) so I was thinking it's a cold start issue.

As soon as I get out of the parking lot and to the red light, the bike has already stalled twice and the check engine light is on. I drive a bit more (like 0.5 mile to see if the light will go out after turning the engine off and on) but it kept stalling.

Spoke to the dealer here and am dropping off the bike right now for them to run it through the computer.

Bummer....

90% chance it's a loose map sensor hose. 2 second fix if it is. Look at the pic below. B is the map sensor and A is the hose. You can see the other one just to the right. These are under the tank but with a flashlight you can see them from under the right front of the tank and get your hand in there to push one thats come off back on. It WILL trigger the engine light, it WILL make it stall, and it's a very common issue.

Spot on Daz.

I kicked myself after I rode 45 miles in 35 degree, windy afternoon to the dealer and after I explained to the tech what was happening, he told me the probable (and very common cause) is the map sensor tubes falling off. He put it back on and problem gone.

I've been a part of this forum since June and have read multiple posts (and your replies) about this problem. I can't believe it just slipped my mind.

The bike is with the dealer and I get it back Thursday. He is working on fixing yet another infamous bug - the belt chirp.

This happened to me and it wasn't the sensor tubes...but the 12 minute adaption fixed it. Just fyi in case it happens again....it drove me absolutely nuts and became a very unsafe problem (i.e. turning left a cross traffic and having a stall a couple of times)

Unless you do something other than just stick them back on, it's just going to happen again. The real problem comes when the engine is hot, you want to be riding and instead you're waiting for it to cool so you don't fry your arms putting the tubes in place.

My dealer removed the tank, removed the map tubes with their cheesy rubber boots, replaced the tube with a stiff fuel line material (a soft line will collapse under vacuum) and then zip tied them at both ends. 6,000 miles later, still no problems.

If you choose to keep the original tubes and boots, I would super glue AND zip tie them ... but that's just me.

Depends on why they came off. one of mine came off because i knocked it off while changing plugs. otherwise in 26000 miles they've never come off. I can't help but wonder if those to who it happens also were due to error on a mechanic's part or thier own or even a factory worker, and it left the factory 1/2 off. I'll probably secure mine next time i have the tank off, but thats rare lately.

As to belt chirp.....been what....4 or 5 months since i sprayed a tiny bit (and i mean TINY bit) of silicone on mine ONCE.....still to this day not even a slight chirp. Food grade silicone, quick shots along the teeth. I didn't even get the whole belt fully coated at all. Works wonders. My opinion is that rubber squeaks. Your belt may or may not depending on any number of factors that aren't problems, just the nature of rubber against a slick surface. Food grade silicone baby ! No reason on earth not to use it if you get squeaks.

Mine came loose several times (within a short period and on both sides under the tank), even after I put them back on. In one instance, the tube came out of the rubber boot and when I put it back in, the thing was actually loose. That's why the dealer dumped the boots. The fourth or fifth time it happened and I once again burned my forearm trying to get it back in, I just called a tow truck (covered by insurance), sent it to the dealer and told them to resolve it under warranty. They did and no problems since. Personally, I think the rubber boot expands when hot and just slides off.

Regarding the belt squeak, mines got 3K on it since the last adjustment and no issues. No unusual wear either.

Belt chirp + CRC food grade silicone (green can) = Gone.
