well I had gotten all my issues worked out on my 98 until yesterday on the way home. Going about 55 I let off the gas to slow for a light. Bang!! One loud backfire, then when rpm's came down to idle the bike shut off. It will now start up and run, but only if I keep it at least at 1/4 throttle, and even then its stumbling some. Soon as I let off it dies. I don't have any clue..... It was running perfectly before. Any ideas??
thanks guys, happy 4th

How is the carb set up on your bike, and what were the issues you were working out?  In other words, what changes have you made lately?  I'm not likely to be the guy with the answers, but when he comes along, I'll bet he's going to ask you that.  You might as well include it here now to save some time later.

EDIT.  Oops.  He came along while I was typing.  Disregard me and my rambling.

what size are the allen bolts for the top and bottom of the carb and where's the best place to find them .

IMHO I would support a local hardware store as in a True Value or Ace for the phillips screws instead of one of those big box places. The local hardware stores give better personal assistance, unfortunately   many have closed due to the big box.

Well, Yesterday I pulled the carb and cleaned everything up really nice. The Fuel in there was a nasty rust color, even after cleaning the carb out only a few weeks ago.  I'm assuming this is due to rusting on the inside of the tank. I'm going today to get an in-line clear fuel filter to add in.
Anway, after cleaning out and putting the carb back together. The bike ran fine yesterday up and down the street a few times. I figured it was fixed and everything was good. Well this morning i went out and realized that i had left the key on and the battery was dead. I put the charger on it for a bit.  Then it fired up, but after a few seconds, started sputtering, and fuel started POURING out of the carberator. I couldn't tell where it was coming entirely but i know some was coming out of the carb vent tube. I know it wasn't doing this yesterday on my test ride because i inspected it thoroghly afterward and even let it run for about 10 minutes with no problems/leaks. I didn't have time to look at it this morning, so i jumped in the truck and came to work.  I'll inspect closer when i get home, but does anyone have any ideas what the issue could be?
Thanks

yeah, that could be it. The fuel does look pretty nasty. I have a feeling i'm going to have to put that fuel filter on thier, then clean the carb AGAIN. The good news is, I think i can have the whole carb apart, cleaned, and back together in about 30 minutes now.
Back to the drawing board. I'm loving this savage, but at this point i'm really wishing it was fuel injected........

Thanks Verslagen,
That is somethingi did not do last time i had it apart. Is this something i can do without taking the carberator completely off the bike?  I'm assuming once I take the cover off and get the float out, it right there underneath?

It's a good bet the fuel tank needs to be cleaned. That nasty-looking fuel in the carburetor came from the tank. By way of the petcock and screen, so they need to be cleaned too. It won't get easier if you put it off. Running on RESERVE probably makes it worse, because all the crud settles to the bottom of the tank, just where RESERVE gets its fuel.
