So I rode down to Carmel for my sister in laws wedding. This morning, I started my bike, but quickly (within 5 seconds) turned the bike off because I had forgotten to take the fork lock off. When I restarted the bike, it was hard starting, and would not stay on at idle. In fact , at low speeds, it sounded like it was backfiring. I had to keep the RPMs above 1250 to keep the engine on.

I was able to ride the 100 miles home without incident because it was all freeway driving. But the second I pulled into the driveway, the engine stalled. And the check engine light was on the entire way. I've even disconnected the battery to see if the ECU would reset, but nothing changed. I'll take it in on Tuesday (dealer closed on Mondays). I'm a bit worried because my wife and I are leaving on a 5 day Sierra Nevada ride (she'll ride her own Kawa Vulcan), and I hope they can fix mine in time. Any ideas what it might be?

Yeah, it's almost surely a map sensor hose come loose. They are small hoses under the tank that are very hard to get to till you realize what they look like and you can actually access them w/o removing the tank by musing a flashlight and looking under it. But if you don't know what they look like and approximately where they are you probably won't be able to see. But those symptoms are exactly what happens with a loose map sensor hose right down to the check engine light. If you want i can try and get a picture tomorrow and post it for you.

Dude! You are a genius! I went out to the garage with a flashlight and sho'nuff, there was a loose hose! Plugged it in and voila! A perfect start and idle! Saved me hours of bike drop off logistics and immeasurable stress! I'll buy you a tank of gas when we ride together! Thanks so much!

I'm just the messenger, that issue has been around since the beginning. I'm surprised you were about to locate them w/o knowing what to look for, but good job.

Now if someone could help me with MY starting issue !!! (mine won't hold idle on cold starts and sometimes hard to start lately)

Can the dealer help out? I've spoken with the Southern Cal Triumph guys in the past and they seem pretty good.

I don't take it to a dealer unless it's absolutely necessary. I don't mean to insinuate i'm even remotely close to being a mechanic, but chances are i'd figure it out before them. Seriously....those clowns are useless most of the time, and i'm not paying some incompetent $90 an hour to tell me he can't find anything wrong. in any case it's not much of an issue because it doesn't happen every time and only in the morning. May even go away now that i have a new tank of gas. Gotta be a tune or adaption thing anyways because it's never done this in 17k till right after i reloaded the stock 1700/tors map. So chances are it'll sort itself in time.
