I'm from CA, but I'm working in AZ for the summer. My wife and I decided to make a trip to the Grand Canyon. We rode from Prescott to the South Rim. It was about 260 miles round trip. It wasn't till on the way back that I noticed my fuel light had not come on till 176 miles on one tank. The highest I've gotten before was 38 MPG and that was just me riding; however, I got 41 MPG with her on the back. I was pretty happy about that. One issue: Yesterday my engine cut out while rolling up to a light. Engine was at 208 degrees. I immediately started it up again and kept riding, but this has been a little issue lately since being here in AZ. It seems that in this heat my bike shuts off periodically, but only while sitting or moving at a very low RPM. I think it has something to do with my idle, because when I'm stopped sometimes it feels like I have to keep it revved or it will die, so I've been letting it sit to see when it dies. Sure enough, after a little while the engine shuts off. Does anyone have any ideas as to what causes this? Is the idle set to low? It hovers around 1.5 RPMs. | ||

I've had that problem with my K1200LT in hot weather. It turned out to be a pinched vacuum hose. Only happened in hot weather, when the engine got hot, and when slowing for a traffic light or toll booth. Once the problem was discovered and remedied, it never happened again. Worth a shot... | ||

Your idle RPMs are correct. I had a similar issue with mine of stumbling and dieing at low RPMs. Turned out I needed to change the front spark plug as it was bad. Picture of plugs and coils. | ||

Just remembered one more symptom from my pinched vacuum hose. The idle speed would oscillate from low to high, and the tach needle would swing back and forth like a metronome while you could hear the engine rev up, and rev down. Each cycle got more and more extreme until the rev down went low enough for the engine to simply stall out and die. If that's not what you're experiencing, it's probably something else and not the pinched vacuum hose. | ||

Mine has done this to me on 2 occasions. Happened twice in 1 day on a 100+ ambient temp day, bike temp got up to 206 and died sitting at a stop light. Second occasion was another hot day, I was slowing down for a stop light, and it just died (clutch disengaged). I chocked it up to it being a hot day and the bike was hotter than normal. Figure with the crummy 10% ethanol gas everywhere now adays, that having it die a couple times a summer is nothing to worry about. Hopefully the new mapping that is rumored to be coming out addresses all these little "quirks"  |
