Fuel Starvation

Post by Stratman »

I'm really fed up now. A few weeks ago, 3 miles down the road, the bike started to cough and splutter and I only got back home by revving it and slipping the clutch, which pulled enough fuel through. This was really similar to a previous thread and I removed the fuel tap diaphragm, which looked past it's best, and replaced it with a new one.

All absolutely fine for 500 miles. Last night, going to the Swan at Yarmouth for a summer evening tootle - a mile down the road and the coughing and spluttering back again. Its both cylinders, so I think it is general fuel stavation. Tank not overfilled so no vacuum there. Limped home, got on my TDM and continued journey.

Any thoughts anyone? I'm starting to think its trade in time, but I do love my Storm (had it 6 years!)

any chance of crap somewhere in the fuel lines???


could be possible if you got close to a empty tank before refuelling.

i would try one of the fuel additives to see if it clears anything
Never argue with an idiot, they will drag you down to their level and beat you with experience.

It's not crap in the lines etc - the fuel that's in the float bowls just gets used up and she dies. Yesterday early morning I took the tank off and removed the petrol rock assembly. Using a Mityvac (like you would for brake bleeding) attached to the diaphragm pipe, I tried to blow through the assemebly with the pet rock turned off - obviuosly nothing. I then turned it to on and tried the same - nothing; applied the vacuum and still nothing. Turning the petcock off and on a few times resulted in it openeing properly with vacuum applied. You can't get into the tap itself without grinding off the rivets holding the end plate, which I did. Cleaned it all up and couldn't see what might have been causing a problem. Need to drill and tap for a couple of screws to replace the end plate, but "on paper" its clean and working. Will also replace the vacuum pipe then rig up a fairy liquid bottle with petrol before refitting the tank to check that the problem is/was in the tap not in the carbs (it can't be both simultaneously though!)

I saw a 2004 Daytona 955i locally - 3000 miles, £4,995 from a Triumph dealer. They're knocking out the last few new ones (in proper yellow!) for £6,299.

We'll see!
