Starting Issue. Runs, Dies, Can't Restart....But

Well heck, I guess it had to happen sooner or later. The last few times out I've had an issue getting the bike started. 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

Starting Issue. Runs, Dies, Can't Restart....But

After I thought I had found the problem, I have not. Still the same thing going on.

Here's what I'm seeing. I start it, idles few seconds and dies out. It may or may not start on a second try, but always dies and any other attempts the engine just turns. Dead, engine turns, no pop. I took the air box off to look at the carb. Just for the heck of it, I tapped the bowl. The bike starts and stays running. Normal. Throttle blips normal. I take the bike out for a long ride and have no issues with accelerating, idle or restarting if stopped. I've done this for the third time today. Always the same issue, always the same cure. The issue shows up on a cold engine. Once warmed after kicking the bowl, everything is hunky dory.

Second and third attempts are after using SeaFoam. It doesn't appear it's working. I've got 200 miles on with the SeaFoam.

Given the tapping on the bowl gets things going, I suspect a float/valve issue. Could this be possible? But only on a cold engine? Again, odd thing is, it runs great after the tapping on the bowl. No issues at all. Here's where I need your help.

FYI-When I bought the bike, the guy had a custom air box and re-jetted the carb. I brought it back to stock parts. Been running great since until now. Thanks for your help!

I would consider the petcock possibly. Somehow a vaccum could be holding up the float valve.. Is the problem the needle/float or the petcock.. Try the petcock mod to see if that affects the outcome.

Look up Heffly, he had same/similar issues.

It's best to keep all your posts about the same problem in 1 thread. That way you, and people that are trying to help, don't have to bounce around from thread to thread looking to see what was done and suggested

I tested the vacuum on the petcock. Opens and moves gas freely.

Definitely sounds like the petcock. Get rid of that vacuum actuated crap.
I use a standard on/off/reserve valve without all the nanny state safety bullcrap.

When you pull the gas line to test flow, you break the vacuum that was preventing it from starting and it appears to test fine. Next time it happens, pull the gas line then stick it back on. I bet it will start. Been there, done that.

I understand what your saying about the nanny state stuff. I'll have to look into changing that over. I like that idea!


Right now though, I'm thinking it's the float/needle sticking. Because I just found a fix by tapping the float bowl. It dies, can't restart, I tap the bowl and the bike runs fine until it cools down.

What's the history of the bike, has it sat for long periods of time without use? Gas left in it unused for long periods of time? If so, i would say your a candidate for a carb cleaning (beyond Seafoam). there's a youtube video on how to do it if your handy or feel handy.
