Just re-tap it to the next size. For future reference, the screws are not Phillips, you need a JIS screwdriver. Give you a bit better control over things.












PS- it's the fuel valve.

More observations from yesterday's fuel issue. The previous day I had cleaned all the jets/ports etc, inspected the float valve/needle etc. All looked great. Not anything strange going on that I could see up in the valve seat and valve/needle looked fine. Buttoned up, started fine went for a long ride. All is well. Yesterday, no start again so here's what I did. When attempting to start I choked, it ran for a couple of seconds then it flat out died.

At that point I wanted to see how much fuel was in the bowl so I drained it and there was maybe a tablespoon that I drained out. That's not much. That can't be right. But the thing is, after a successful ride. I turn off the bike and walk away. Float bowl should be full, shouldn't it? Here's where my knowledge is lacking. How much fuel should be in the bowl after a shutdown? That bowl should be "full" when shut off....shouldn't it? I know the float valve is regulating things on and off, but at shutdown, shouldn't there be more that a tablespoon of gas in the bowl?

I have a nearly new Pingel fuel tap. I will let you have for 1/4th the price of new. Let me know. I still think your problem is in the float/needle set up, I bet it is hanging somewhere when on the kickstand. Try righting your bike before trying to start, and see if that works, give it a minute to fill the carb.

It's really interesting you mention that. I wondered about that myself. On the stand it has a good lean on. Here's why I think you're probably right. On one occasion of trouble shooting, I had the bike on the stand, sitting upright, I hit the start button and it popped right off. Then you get into the cold/hot issue. It would only do it when cold. When I could get it started, when out for a ride with multiple shut downs, it would start fine on the stand. Who knows, who cares...it appears to be working now.

Thank you everyone for your input and help! I really appreciate it.

I've had two days with a successful cold start. The issue was so consistent I think it's fixed. This after a thorough carb cleaning. Uncertain of exactly why it was doing what it was doing, I guess it doesn't matter as long as it starts now. On start, it's a bit rough, needs a little throttle to smooth out for for a little bit, but finally settles out. I generally don't choke it unless it really needs it, that is will die out without being choked.

I've got Glens A/F adjuster on the carb. I've had it about 2 1/2 turns out. No backfires, when the throttle is blipped there's no catch up or lag back to idle, no hesitations in throttling up in any gear. I think it's set up about right.

I need to find some kind of tach to use to set idle speed. I'm not wanting to spend big bucks on it. I wonder what the shops use when bikes come in with no tach. Anyway, I think the cold start issue is fixed.

I bought this one for my 1300 S, and it works well. It said make offer, so I offered $10.00 and seller said OK. It took 4 days to get here. Simple hook up.Mounted it to the top left riser bolt.

I always choke just a little, as soon as it starts I push the choke in and throttle it to warm up. The first time it died when I took it off choke. On restart it would run rough, then die out. No restart/no firing. I thought I had flooded it. I waited while the battery recharged and attempted again and got it going. Today, same scenario only after the wait....dead. Just turns over.

Here's what I've done.

1/ Checked the shut off valve/gas level. It's on and lots of gas. (I've closed it by mistake before).
2/ I took the air filter cover off. I checked to see when I blipped the throttle that I'd see a thread of gas going into the throat of the carb. Just a little spit on some blips, no stream other times. I believe I should be getting a steady stream with each blip? Correct?
3/ Tested vacuum line to shut off. Gas flow when cranked.


It appears to be a carb issue. Just guessing. Not a mechanic but learning.

I'm guessing this is as good as place to start as any. I mean, it's either no spark or no gas. It's clear that it appears to be starved for gas with the throttle test.

So now what? Is there anything else I should be checking? I'm thinking there's an issue with the throttle pump (can't remember the right term) isn't there a rubber component creating a vacuum? If It's cracked, it won't work properly. However, it's probably been 4 rides ago I had the first start issue. The bike (throttle) responded normally straight through all the rides. No hesitating etc. Clear throttle up with power. So not sure that's the issue. A bit confused at this point.

Vapor lock maybe?

Now is when I rely on the collective genius here on the forum for help. Thanks guys. Rog
My 2003 VTX1300 ran fine when I put it in storage 5 years ago

When I started it up a couple of weeks ago ,it had the same exact issue you are having

After adding new gas, a can of seafoam and taking it for a ride at WOT , mine now will only bog/stutter when the engine is cold

I'm thinking that the VTX is either still jealous of my new ride or it has a dirty jet
