Need Help With Carb. Problems Please!!!!!!
So today was a nice day and I actually had some free time so I got the bike out of the garage and charged the battery and jumped on to go for a ride and no go. The bike was very hard to get started and once it did start it only runs for about 60-90 seconds and then shuts off, it will immediately restart and do the same thing again. So I thought that maybe it just needed cleaned out so I headed down the street and before I even clicked out of first gear the bike shut off, again it immediately restarted but the problem persists and I am at my wits end. If there is anyone out there that has any ideas they would be greatly appreciated. So for the long post just wanted to get all of the info. out there. Thanks in advance.

Bad gas, clogged petcock filter, clogged in-line filter. Check battery cables. If their somewhat loose this can happen. Most carb problems aren't carb problems.

How long has the bike been sitting? Could be water in your float bowl. Take the bowl off and drain it. Make sure your float moves up/down. How old is your fuel?

I would take the carb off and clean it try soaking it in Berrymans B-12 or gunk carb cleaner. It will be necessary to completly disassemble it and remove all rubber and plastic parts before soaking it. Then blow it out with compressed air real good that will take care of the carb. Then check the other things mentioned here an old trick to see if it is a fuel problem is to squirt gas into the carb throat when it starts to die. BE CAREFUL here that you don't get burned if it farts while you are doing this.

Is there a drain bolt under the carb bowl? If there is, next time it stops, turn off the gas valve immediately, and see if you can drain any gas out of the float bowl. If the bowl is empty, the floats are probaly sticking or the filter is clogged. It is possible the main jet or emulsion tube is clogged. It could be water in the gas.

Check for a cracked or split vacuum line from the carb to the fuel petcock.
