I know this has been covered by myself as well as others, but I am still having a problem with the bike not starting after I run it. It is irritating as well as embarassing to not be able to get the bike started when I stop somewhere. Dealer doesn't seem to know why, tune certainly can't be going bad every other time I ride it and the battery and ground are good. I've tried the silly open the gas cap, turn the killl switch on and off while standing on one foot and spinning in circles while chanting an obscure mantra, but I am at a loss and getting disheartened with the quality of this bike after only having it for 9 months and 14,500 miles.

TT, Would you go to the user contol panel and list what Triumph you have? Off hand I'd suggest the timing sensor (I'm guessing the starter is spinning the engine). Next guess is the throttle position sensor, but that's weak if the bike starts okay when cold.

Is the problem within a couple of minutes of turning the engine off or when the engine temp is in the low 100s, for example.

I reset the TPS when I reloaded the tune last time. The bike generally does start fine off of cold. It seems to be only after I run it hard and stop for gas or a short period. Thinking on it now if the bike sits until nearly cold again it'll fire up. Starter is turning the motor, just a weak firing and then it dies barely stays running after it does light. Brad, 06 D955 if that's what you mean by listing the bike. Just a bad day in Triumph land and need to blow off steam.

I feel your pain, triumphtimes! here's a chronological account of the troubles with my bike:
1. Purchased a new '06 955i Daytona on 6/12/07. When I went to pick it up it wouldn't start; slow cranking. Dealer replaced the battery. When it did start, wouldn't take throttle for 15-20 seconds, then revving it produced a lot of fuel smoke- not a good sign from a bike with 4 miles on it!
2. Subsequent cold starts required 10-15 secs. of cranking; sounded like the engine was gradually getting fuel or clearing a flooded condition.
3. Two days later, at an errand, attempted to restart after I shut it off for 2-3 minutes- wouldn't crank fast enough. Fellow Triumph rider parked next to me went and got his cables. Got a jump and went straight to the dealer, who replaced the battery and found that both cables were loose. Apparantly his directions to replace the battery weren't followed.
4. Cold start problems remain; now becoming difficult to restart hot after it has sat for 15 min. or more. Prodigious black (fuel) smoke upon restart. There is also hesitation and stumble when blipping the throttle from idle position, making it impossible to change down cleanly, and a serious hole in the powerband between 5000 and 6500 (this didn't show up until after break-in, as I didn't hammer it until then).
5. Install Yoshimura TRS Ti can and get the off-road tune from the dealer. Power is better everywhere but above problems still persist. Dealer synchs. throttle bodies and sets/adjusts tps at 500 mile service. Vibration (which I've posted about earlier) doesn't seem as bad, but other problems persist.
6. Dealer orders new injectors. These are installed yesterday, but the service manager/lead mechanic calls to say they didn't help, and he's calling Triumph today for a solution. I say keep it as long as you need (I miss it already, boo, hoo!) and keep me posted.

I really don't think anyone knows the problem and I don't think there is a known fix for it and I also DON'T THINK TRIUMPH WILL TRY AND FIX IT OR FIND AN ANSWER. I think it'll be a problem put off until the bikes are all out of warranty. Cheaper to replace batteries and ground cables, small things than it is to research and fix a potentially major issue with the bikes. I'm wondering if it isn't a computer issue causing the mechanical problem and I also think I'm stuck with the problem until I decide to get rid of the bike. Sad because I really love the thing.

TT, Going through the service manual I have to add the air temperature sensor.

This is when you miss having a bike that is popular for racing. Not just Triumph but all factories ignore these problems because they effect a small percentage of production bikes but independent tuners usually come up with a cause and solution. My 02 was hard to start at first but fotunately didn't go over to the dark side. If Rickster didn't find the problem with his procedure and assuming you both have a similar issue your reduced to replacing sensors, connections and maybe the ECU - or you can trade now.

Have you seen that new Ducati?

That new duc is sweet, but not an all rounder like the Daytona. I bought this bike to use for everything as it really is set up for just about anything one wants. It is comfortable, fast, handles decent, gets somewhat decent mileage and was cheap to boot. The duc isn't really cheap, isn't really comfortable or made for a tall individual and only get about a 100 miles to a tank. I refuse to buy a Jap bike because of their bland build and ride. Secondly I bought the Daytona based on the reliability of my 00 RS which was/is a very solid bike. It seems as though development over the years and refining a bike also means some cut corners and quality issues. I have put off taking several trips this year because I don't trust the bikes ability to get me where I need to go and am worried about the trip I have planned in October which consists of an ss2000 ending near elpaso tx and then on to alabama for the vintage motorcycle days. Brad I haven't had time to check out your suggestions, but will this weekend, thanks.

Good point, Brad; you would think the check engine light would come on to indicate a sensor problem, but who the hell knows?!?! All I know at this point is that I haven't heard from my Triumph guy since Wed., so that can't be a good sign. If it isn't 100% by the time I get back from Canada next week I'll probably put it in the truck and take it with me when I go to Calif. week after next. A friend of mine is the service manager at a Ducati/Aprilia/Triumph/etc. dealer there and is one of three people in the world I would trust to work on something of mine, so if our local guy doesn't fix it I'll get Robert to give it a look. My feeling is there has to be a solution somewhere. If it wasn't under warranty I'd have dug into it myself already! It's a shame for an otherwise excellent bike to have flaws like this. It's a good thing I've been so busy building my shop and haven't had time to think about all the riding I'm missing!!!

triumphtimes · 08-26-2007, 05:04 AM

Seems my problem is when the bike is hot or after a good ride. I dread stopping for gas anytime because i know it's probably gonna give me a problem. Sometimes if lucky it starts very weak, but many times, hit or miss it doesn't want to fire at all and if it does it'll die right away. Something has changed or gone bad since buying the bike because it did not do this when it was new. There are no error codes and the MIL has never come on.
