My bike would run for a while then die and would not start again until it set for a few hours. now it wont start at all it just back fires and shoots fire out the pipes when it tries to fire off. I drained the fuel tank and carb bowl and put in fresh gas but still have the same problem any ideas what could be wrong?

I would think about investing in a carb re-build kit.

Remove and clean the carbs. Also clean the water trap on the petcock, (gas valve), if your bike has a water trap. Remember to balance and sync the carbs after installing.

Hi and welcome to FixYa,

With the indulgence of craigjamesbt...

A few additional ideas to consider:

• it would be an electrical/ignition issue if 1 & 4 or 2 & 3 will not fire but not 3 & 4;
• almost always, raw fuel on exhaust indicates a flooded engine. A flooded engine would most likely be a carb issue;
• best way to determine if it is an engine concern is to do a compression test;
• a way to test the right carb pair is to deliberately starve them of fuel by temporarily plugging/blocking the inlet port/seat with rubber similar in appearance as to those used for glue gun, not installing the needle and float. Assemble the carb and install. Start the bike and use/spray carb cleaner on the right side carb. Note if 3 & 4 will fire even intermittently.

Theres fuel starvation, the carbs are not getting required fuel in other words the float chambers doesnt get the correct amount of fuel .
Check the fuel flow from the petcock to the carburators.
Check the float pin and adjust accordingly to get the right level inthe float chamber of each carburator.
Hope this helps!

Take the carburetors apart and either rebuild them or clean them thoroughly.
