It kicks right off, runs for just a couple of seconds then quits. If I try to give it any throttle it quits immediately. It won't run long enough to warm up. Trying to restart immediately doesn't work. It will start (then quit) again after a couple of minutes. The bike only has 3500 miles on it. Ideas? |

Oh yea. About 90% of the Blasts problems are caused by leaky carb boots.
Replace the rubber piece shown below:
It costs about $7.50 and is known as a Manifold Coupler by Harley. Everyone else calls it "the boot." |

I have had this problem and if I hold the clutch in it will stay running and as soon as the clutch is let out it will quit,
it seemed to cure itself but try holding the clutch in and see if it will still run,
if that is the problem use a piece of double sided velcro to hold the clutch in when warming it up, also you can use the velcro to hold in the brake lever this lets the air in the lines move up and out and will have better brakes in the morning,
I do this once a week to my bike I pull the brake lever in and then tie it there by a plastic tie wrap or the velcro. |

I've had that problem too. That's a safety switch issue. I never figured it out, because as you say, it cured itself eventually. But I think that part of the bike thought it was in gear (even though the neutral light was on) and was killing the engine because the kickstand was down. If you raised the stand, the bike would idle with the clutch released. |

If that boot is torn then the bike will run super lean, that condition is called false air. But the bike most likely would sputter and die. Not just shut off. If the bike is just shutting off then you should check for anything that would warranty that sort of thing. ex. kick stand sw., kill sw., ignition, etc. |

Also check that the tank vent line isn't block.

I have a '01 Buell that is starting to have issues. Once I have been riding it for longer than 20-30 minutes it starts to sputter than just completely shuts down. Today it just stopped while I was going 35 mph! When I try to restart it, the engine turns over but it just won't start. I usually have to wait ten to fifteen minutes then it will crank right back up. Does this sound like a boot issue to anyone? |

Sacha, that sounds more like a blocked tank vent line. Next time it happens, see if removing the gas cap fixes it.
If you have an 01 Blast with the original Boot replace it. They go bad often, and there are a bizarre number of symptoms that can occur when it does. It's a cheap enough part that it's worth replacing periodically just to ensure that it's good. |

Well it wasn't the "boot" I didn't think the symptoms sounded like an air leak.
Turned out to be a plugged slow jet.
I talked to the Buell tech at my local HD dealer and he said that the switch to alcohol in gas causes this. I guess they had a lot of them last year. I'm guessing that since this bike wasn't used much last year there wasn't much gas run through it, so the problem shows up. If you run your bike a lot, then the goo gets diluted and doesn't cause a problem.
Now the new problem.
It's backfiring through the carb.
If it isn't one thing, it's another. |

Yeah, I had the same problem. I changed the boot and cleaned the carb as it had been sitting for a little bit and it started just fine. I too have had the issue with the back fire and at this time trying to figure out wth that problem is. If any one figures that one out lemme know its really annoying me LOL.
Does anyone also know if I need to rejet or make adjustments to the carb since I took it from 3500 ft MSL to about 5000 ft MSL? |

How do I go about fixing a blocked tank vent line? Is this something I can just clean out or does it need to be replaced entirely? |

Sacha, its the rubber hose that comes off behind the gas cap that is blocked. I'd pull it off of there and see if you can blow air through it. If that side isn't blocked, put a hose onto that nipple, loosen the cap and see if you can blow air into the tank. That will tell you which side is blocked.
It may just be that the hose is pinched somewhere. |

Sacha-
I'd look more towards ignition problems on your bike. Especially the the ignition module and the coil.
When your bike is cool, pop the cover off the ignition module. Get a hairdryer or heat gun and put some heat into the ignition module. If it's bad, your bike won't start - even though it normally would.
I think testing the coil is probably a lot more straightforward.

I have experienced all the issues posted on the forum and then some. I finally gave up on the Harley boot and bought a length of hose from Napa auto parts and make my own. It seems to be a much tougher rubber and I haven't had to replace it yet.
The current issue is the bike starts fine and runs in neutral, but when you put it in gear and the clutch engages the engine stops. |
