About two weeks ago on a long road trip, my Blast began to develop a bit of an issue. At around 70 miles an hour, especially up hill, the bike would begin losing power. It’s never been an issue before. From first gear through fifth, the bike would be fine up to between 70 and 75. But is seemed that if I tried to push the bike past that, it would begin gasping until I let up off of the throttle and it would pick up again.
I had hoped to get the bike home and check it out, but the battery died on the way home and I wasn’t able to get back to it until the following weekend.
After replacing the battery and taking the bike out, it began to sputter and eventually die every time I gave the bike gas. At first, I thought it might be low on gas from the long ride so I flipped on the reserve to no avail. The bike completely dies about 6 blocks from home. After I let it sit for a bit, I could get the bike to start and idle in neutral, but if I attempted to give the bike any gas at all, it would sputter and die.
Any thoughts? |

Sure sounds like a fuel issue.
Have you changed the fuel filter lately?
Maybe just a bad batch of fuel.
How long have you owned your Blast?
What, if any, were the last maintenance you did on the bike? |

Fuel filter sounds likely - you have a screen over the fuel petcock and reserve standpipe inside your tank, too. Has there ever been gunk in the gas tank? If you fuel your carburetor from an alternate source such as a baby bottle it will tell you if the gunk is in the tank/filter area or carb. If it works with the baby bottle and changing the fuel filter doesn't do the trick you'll have to take the petcock off and check that screen. Remove the tank first and angle it rear-end up so the fuel doesn't fill your shoes when the petcock comes out. You never get it all with the siphon hose. What's your battery issue? |

The Blast is a 2005 and I've had the bike just a little over a year and have changes the oil and oil filter twice, but I have not changed the fuel filter or checked it. Last maintenance was changing the oil about 3 weeks ago and I did add new front turn signals. The only issues I have had involved tightening the boot to the carburetor (july of 2010) and replacing the battery last week. The only issue with the battery was age as far as I could tell. The suggestions you guys have made make sense and I'll give them a go tonight or Friday.
Thanks for the advice! |

I'd suspect an intake manifold leak. Check out the intake coupler (boot) and make sure it is in good shape and not cracked. The clamps need to be snug, but really cranking down on them can damage the boot.
If the boot looks good, I'd pull the carb bowl, clean the jets, and make sure that the float isn't sticking.
While your at it, just turn the petcock on with the fuel hose disconnected from the carb to make sure that you have good fuel flow. If you don't, pull the petcock and clean the screen. You should probably make sure that the petcock screws are tight anyways, the do rattle loose over time.
If all that fails, It's time to look at the electrical system - coil, ignition module, spark plug, wires... |
