I was cruising along and all of a sudden I felt a loss of power. Gave it throttle and that didn't help. Must be running out of gas I thought? Seems too soon but I put it in reserve and pulled into a side street to stop and turned off the bike. A quick glance and things seemed to be ok. Put the petcock bag to on and started her up. Seemed fine so I did a uturn and pulled back out onto the original street. About 20 seconds later I felt a loss of power again but was coming up to a gas station. I pulled in just as the engine sputtered to a stop and rolled up to the pump. Perfect. So i filled her with gas, took 3 gallons exactly. Started her up and just as she came to life, she died again. Tried to start again and nothing. So i rolled off to the side of the building, sat there for a moment thinking, then put her in reserve. Started up fine. Idled for a couple minutes then took off. Put it back to the on position and was good for about 20 seconds before it started to lose power again. Back to reserve and everything is fine. Hmmm... starting to see a pattern now.... Got to my destinination (10 miles later), then turned around and made it all the way back home on reserve with no issues. Then the next day I made it 25 miles to the dealer on reserve with no problem.
They said it was hard to diagnose but they finally got it heated up enough to find out it was an electrical problem. Some electrical pick-up I think they said. Which of course had to be ordered. So no bike till next weekend. Bummer.

Anyone understand what they might be talking about?

Here's the deal,

The ignition pick-up sensor tells the brain when to send a signal to fire the sparkplugs. It is on the right side of the engine (when sitting on the bike) and when it goes bad it will cause the bike to shut-off as it gets to operating temps.

Being able to ride while in reserve is contrary to this as being your problem as the ignition sensor will cause the bike to shut-off no matter where the petcock is set. Unrelated parts of the bike.

You may find that the petcock is faulty or the tank vents are faulty instead.

Greeeaaaaaat..... so if the ignition sensor is what they were talking about, then I'm gonna get the bike back, still have the problem and end up having to take it back to the dealer again. :roll:

Thanks for the reply.

You may want to give them a call and make sure they know all of the facts as you have presented them here. The symptom is like a bad ignition coil, however, you mentioned that if you have it on reserve that there is no problem, which takes the ignition coil out of the culprit box.

Just a thought

Lurch, this is what I was thinking too, but then again I don't think it could just be a clogged petcock for instance, because it seems as though the bike needs to be warmed up before the symptoms reveal themselves. Weird, eh?

And ya, I did explain to them what I explained here.

I'll let you know what happends later this week...

My guess is that it is the ignition pick-up sensor. Last time I bought one it was $65. It's easy to install, An hour of labor is too much time but that's what they'll probably charge you. I think the fuel thing is just a coincidence.

By the way, what are you riding?

Oh, they won't be charging me anything. 240 miles on the clock. '05 T100. :wink:

On an 05 T-100?

That ain't no pick-up sensor problem, there's a problem with the petcock or vent. I bet a cold Guinness on this one.
