This has happened twice now. Both times with plenty of gas and oil. No warning lights at all. Today I was on the highway doing about 70 through a long slow right bend, just as I straightened up the bike just stopped running. No warning, full tank, just stopped. I checked the oil light, not on. Pulled the clutch in, down sifted to neutural, turned off the ignition key for 5 seconds, all the while gliding down the highway, then turned it back on. One push of the starter and it fired right up and went the 19 miles home without incident. This is similar to what happened 2 days ago. Thought is was low oil, so I did a oil change and it was only a little low. does anyone have any ideas????? I am thinking electrical right now. I am going out to check right now. It's 108 miles round trip to work and I don't want this to happen and not restart when I am too far from home. Bike has 20,000 miles on it.
Thanks for any help.

first thing that springs to my mind is the rev limiter, were the RPMs high enough to have hit the rev limit?

No, I was in top gear and only doing 70. The rev limiter would just stop the motor from reving any higher I would think. Not shut down the motor altogether. Right?

No, not always. I have hit mine a few times and had to shut the key off as you describe to refire.

In 5th at 70 and a 19 tooth I shouldn't have been anywhere near rev limit. I make this ride every day and done that part at 85 when no ones around. Also I was only doing 60 the first time it did it. the way it stops, it's like it was shut down by something. Wait that gives me a thought. the kick stand shut off switch got messed up awhile back while I was in florida. I used a paperclip to by pass it at the headstock connection. I fixed it 6-12 months ago. maybe somethings gone wrong there?

I was just explaining that the limiter does that not that you had hit the limiter at 70 in 5th.

The stand switch could do that if there was an intermittent connection there. If you had an issue with it before that is the first place I would look. If not that then look for any possible loose connections like maybe the coils but not limited to those.

I have never had one do it before. Would that mean it is going bad????
Also the kick stand switch seems ok, but I am going to jump the connection anyway and see if that stops it. as well as looking everywhere else.
It doesn't look like I will be riding to work in the morning!

check your battery connections first

Thanks, it was the first thing I checked.
I went ahead and put a jumper in the connection behind the headstock where I had done it before. A lot easier when your at your own shop than out on a construction site 900 miles from home. Anyway for those that may have that problem of something jumping up and bending the bracket that holds the kick stand switch in place. Just follow the wire harness from the switch up and just behind the headstock and under the tank is a connection. Pull them apart and you will see 3 female wire connections. Find a large paperclip, little ones are not tight, and jump the 2 outside ones. Cover with some electrical tape if you have it and start the bike. You should be able to put it in gear while the stand is down. If not your year model may be different, try a different combo. DO NOT FORGET TO PULL THE KICKSTAND UP BEFORE RIDING. For us forgetfull types, fix as soon as possible.

to the dog33, thanks for the input. I have found over the years that it is easier to come up with ideas when there are several minds thinking on it.
If anyone else has any more ideas, I am all ears.

This is absolutely identical to what was happening to my 04 about a year ago. Drove me and the mechanic nuts trying to find it - in fact I was about to order a new computer (at enormous cost). Turned out to be a dodgy coil putting out a marginal voltage. Normally it was just enough to run the bike but occasionally it'd drop a little and the bike would die. The coils aren't cheap in anyone's language, but they're a lot cheaper than a new computer.

Mountainman - the bike only has 20,000 miles on it. I have been riding for 41 years and only had to change out 1 set on a bike that I put 160,000 on.

Sandmann - The bike dieing because of a weak coil, now there's something. You would think that it would just misfire. Does the brain box on the Triumphs have a fail safe program in it that if anything goes wrong, even small suff, that it kills the bike? That would get me killed driving in and out of Dallas the way I do.

swap it out with a known good one. Yeah right. Which one is bad then in your case? Not like you can swap the coils with each other and move the issue left/right.

Coil failures will mimic dirty idle circuits too. When they do, the bike shuts off. No way to really discern which cylinder lost spark.

So a known good coil would need to be test run in both the left and right sides.

Bad procom cdi will mimic one of those bad coils that mimic dirty idle circuits.

There is a resistance ohms check you can do, but you can't perform that test while the coil is under load. the dinqa wrote once of a device that would test a coil under load. dern might expensive that lectric gadget is...

The full tank each time thing has me thinking vapor lock. Have you checked your tank vent line for kinks or obstructions? A blocked or sticky tip over valve could do this as well (located along the downtube in the vent line).

What is the spec on the resistance ohms check. Might as well do it all.

The second time it had just been filled and I had put no more than 10 miles on her when it happened. The first time there was at least 2/3 tank. But I will clean them up none the less as long as I have the tank off. Thanks

That's what confused me & the mechanic too, with a bad coil I would have expected it to just run on one cylinder. We were looking for blocked breather lines, bad kill switches etc. I knew it had to be electrical due to the instant way it shuts down & restarts immediately - with a fuel or air problem the engine would sort of "fade out" and be hard to restart. The problem also got significantly worse when the bike heated up in stop-go traffic. The mechanic measured the output voltage of the coils (must have a big volt meter, mine only handles 500 volts!) and decided one coil was ok but the other was marginal. I was skeptical & thought he was grasping at straws buta year later and it hasn't stopped running since.

I just did a quick check and found most coils have between 20,000 to 40,000 volts. I don't have anything that reads that. But I also checked out Nology, they have replacement coils for just $70 each at New Level Motosports. That beats $150 ea at the Triumph shop and everything I read about them is top notch. They put out 45,000 volts to boot. If the coil is the problem, I am buying 2 of these bad boys.

Have you checked your pickup-coils? This problem occurs with the Bonnies as well and usually the pick-up coil ends up being the culprit. I forget the gap that is needed behind the timing cover but if that gap is off then it will msifire like this. That is the first place I would look for especially considering the bike is about four years old now and it cuts out momentarily.

I just had the same thing happen to me this this past friday. I had about 40 miles left of a 700 mile trip and my speedy just died. Turned out to be a bad ground connection. There are two wires coming off the negative terminal. About five or six inches from the battery there is a plastic connector housing for the smaller black wire. The male side of this connector slipped the housing and disrupted the ground. I pulled the connector out of the housing and plugged it into the female connector and presto she fired right up. Did a more permanent fix at the hotel and drove it home sunday with no problems. Funny thing is I discovered the problem after calling AAA and having to pay $55 for the motorcycle upgrade. The fellas who responded were bummed because they didn't get to collect the 50 mile tow fee after traveling to the middle of nowhereville. So I tipped them $20 each for their troubles. At that moment I didn't care, I was happier than a pig in you know what because I didn't have to leave my bike 700 miles away from home for a repair.

I believe the pick up coil is ok. Your terminalogy of misfire confuses me though. Do you mean it misfires and keeps running or?????????

The ground wires all seam firmly connected, I do believe at this point that the Sandmann has the right idea. It's the coils.
Oh by the way if anyone wants to buy these coils go to Newlevelmotosports.com. I ordered mine on friday evening at 6 central time. They gave me free ground shipping by way of USPS and I got them TODAY. When the wife emailed me she had them you could have floored me with a feather. These guys are fast.

One last thing a couple of members (including myself) have had is an intermittant shutdown in the lower to mid range throttle positions. It felt similar to hitting the rev limiter. I disconnected my TPS sensor and no more problem. When I checked the sensor the variable resistor was messed up. The resistance values are found here at Triumph Twin Power. There are no real problems running with it disconnected. Good thing to check. Mine has been disconnected for a couple of years.

Thanks to all for all the info. I believe I have the problem solved now. I put the Nology coils in last night and rode to work today. 108 miles and no problems so far. If it stays good to the weekend, I will do the AI removal along with adding a bigger main jet and remove that snorkel. Not sure if I want to do the baffle removal yet, let's see how it goes. I kind of like the quite while on the back roads during the last leg home and on the weekend.

Hi,

My '04 is doing the same thing, used to be a brief cut out and backfire, now is a cut out. I'm thinking I have a bad coil as well but saw many posts about the pick up coil gap.

I could not find anything on the pick up coil's location to check it, and I'm sorry to say I do not know where it is. Any help would be much appreciated. I'd prefer not to just hang a new part with our some due dilgence.

Thanks!

The pickup coil is under the stator (alternator) cover on the right hand side of the engine. You'll see a wire harness coming out from there. So what you need to do is pull the cover (make sure you have a replacement gasket ready) to check and/or adjust the gap on the coil. Do this while the bike leans on the kickstand and you'll loose next to no oil during the process.

I have am intermittent problem and was wondering if the pick-up coil is the problem
About 8 months ago i was riding home and it misfired on 1 pot (i think from memory it was the right )so straight away i though of the CDI as a lot had been talked about this at the time , so i ordered a procom and 2 nology coils and leads (wires )
With these in and new plug it still cuts out on occasions
on Friday i was out for 5 hours and no problem , on Sunday i got about 40 Ks and it died after 1/2 hour it fired up fine and i rode 20 Ks then it died again
I got trucked home and had the tank and seat of and with the motor running i tried every connection and twisted a turned every bit of wire i could get to and nothing
I road of and 15 Ks away it stopped again
If i try to start after only 15min it will if i use the choke but wont rev or run without it
If i wait about 1/2 an hour it starts fine
Now i have been told the choke thing could be only helping if the spark is low ? and not carby related
Now sorry this is so long but what i am getting to is, do you think it could be the pick-up coil
I am going to get a new one anyway but all ideas would be much appreciated
Thanks

I've had similar problems... one time it died on the highway for no apparent reason, then restarted fine an hour later and ran flawlessly. Mechanic at the dealership put it down to a blocked carb breather pipe. A few months later it began dieing intermittantly but would restart immediatley - this time it turned out to be a bad coil, but you've already replaced yours. Try checking all the breather pipes below he engine for accumulated road grime etc.

Given the fact that you changed everything else, it sure sounds like a weak spark due to a failing pickup coil. Remember to check the gap. It should be .8 mm.

Because it doesn't start up right away, it doesn't sound like the sidestand switch.

Keith and Matt the breather hoses have been checked a couple of times
I went to order a pick-up coil today and ended up trading my lovely America in on a new T100 , British racing green and cream
The deal is about 99% done
Sad to say i have had the America 5 years NOW and put 94000 Ks on it
