My 98 Honda Shadow was running great and smooth till I washed it. Now its backfiring and running rough.
Water in the carburetor

valves need to be adjusted every 6000 miles your way past due also your carbs need to be in sync together a shop has to do this work
SOURCE: motor bogs when you give it gas
It is a fuel problem, it can be filter or rubber membrane,they are placed in the valve for fuel.

It sounds like you may have or will be jetting your carbs. I did this using the directions with the kit and used the Clyman manual for this bike to show me step by step how to remove the carborator. You will only need to attach 2 of the 4 hoses on your carb. syncronizer. If I remember right, you need to remove the bolt-on cooling fins to expose the engine block. The is a black screw or bolt that you take out and screw the threaded metal adapter of the sync tool. Be careful using the sync tool. Be very light on the throttle or the vacuum in the cylinder will **** in the mercury from the sync tool - not good. The problem you are stating on idle & backing off sometimes happens when the carbs are running rich (too much fuel) Hope that gets you in the right direction.

Replace the spark plug caps and try again. On Honda's the cap is often part of the wire (a dealer part) NGK makes some inexpensive plug caps about $5 each. They should OHM out to 5000 anything above or below and you need to replace them. This should fix the problem.

More information is needed - aftermarket pipes? any carb work been done to it? is fuel fresh? air filter condition? how are the plugs burning? oily black, white/tan?
