So yesterday i was riding with my buddies, there was about ten of us. We had already put on about 100 miles and stopped for lunch. We took off and a couple of minutes later my bike started sputtering and popping, it got worse, seemed to me like it was missing really bad or only hitting one cylinder. I pulled over and so did everyone else. I pulled off the scoop and checked the sparkplug wires and they seemed ok, we decided to try and limp it to a better place to stop. Got on it and rode it, ran like $hit. The question came up if it was over heating, i thought the fan was on when i pulled over the first time, but some others didnt remember it, luckily we were only about 20 min from someones truck so we packed it up and took it to his house. When we got there, i pulled all fuses and check agin, moves some relays around, checked all the plugs, didnt do anything really. Took it out and seemed ok, chanced it and rode it home, tood about 2 1/2 hours to get home and it was fine. My question is what would make it run like that, if it did get hot, does is just stop one cylinder, i had no lights to say anything was wrong, and when i was riding it, it would surge, then sputter, then surge, but it was back firing at the same time it was sputtering. I had plenty of gas. | ||

There is a feature on the XBs which will turn off the ignition to one of the cylinders (I think the back one?) if the temperature is too high according to the sensor. If the motor was actually overheating or the sensor thought it was overheating then that could happen... | ||

That's good to know about the over heating. I had no idea they did that and it would scare the poop out of me. My first guess would have been spark plugs too because that is exactly how my old bike ran when I fouled a plug. | ||

Engine temp sensor I bet. Mine was doing something similar. It would actually stall several times if the RPM's dropped. Replaced the sensor (you need a special socket) and all was good. Sensor was fairly cheap. | ||

it is fine now though, i would think the sensor would just go bad and not kida go bad. i thought it might have been the sensor, it is almost like there was a bad connection somewhere. it sucks when something fixes itself, because i know it will happen again somewhere, hopefully this time i wont be in Copperopolis! cuz that is a long way from home. i have to put in the shop to get the tps reset so hopefully there is a code in there or something they can see to tell me what happened. assuming it will log that kind of thing. | ||

Why are you having the TPS reset? And did you change or work on anything before the ride? What was the last thing done to the bike before you took that long of a ride? Did you buy gas when you all stopped right before it started miss firing? | ||

i am having the tps reset cuz last time i had it done, sometimes it hangs around 2K. the only thing i did before the ride was change my oil and primary oil. i had the same gas i had in for about 70 miles before it happened. | ||

Pupu, You can check the trouble codes yourself with only a short jumper wire with two small alligator clips. Record the engine light flash sequence. My advice is, if you have a lap top computer and know how to turn it on, then order a VDSTS from American Sport Bike. For about 200 dollars you can get trouble codes and then clear them manually. You can reset the TPS in about 5 minutes. If you have a Buell you need the software unless you live close to a dealership and have deep pockets and more patience than money. | ||

Also FYI the engine temp sensor trouble code is 14. On a side note, the engine light should have flashed if you went into the overheat/half fire spark mode according to the manual. If your bike is hunting and idles at 2000 then a trouble code would probably solve your troubles. If you pull the codes then post them, I or someone will give you the fault condition for that code. It is quick and easy. I keep a jumper wire and a code list under the seat. If you want the procedure then give a shout. | ||

When my temp sensor went bad, I never got a trouble code. Also, it didn't always stumble, etc. It really depended on how long I had been riding the bike and what the outside temp was. It had good days and bad days but it got progressively worse. After changing it, I noticed that the times and length that my cooling fan kicked in changed. For the cost in parts and the socket (I think I was in for around $25), it may be something worth checking. |
