Carb maintenance headaches

[Anonymous]

:? I have an 81GS850G that seems to have a recurring problem with gummed up carbs. Its been to techs three times to clear it up but always seems to creep up on me. Aside from adding gas treatment, draining the reservoir after rides or other " easy outs" I'd like to get them rebuilt or replace them with new or rebuilt carbs. Any suggestions ? How costly is this ?

Thanks for the info. That site has some very useful information.

Have you tried draining the bowls into a clean cloth, to see if there's any visible contamination in the fuel? How's the inside of your fuel tank?

It takes a good year or more for fuel to go stagnant, especially if the tank is kept nearly full. If the carbs were properly cleaned once, they shouldn't gum up at anything resembling a regular interval; it should take a long time.

I'd try an inline filter, and monitor the carb bowl fuel from time to time.
