Cleaning your motorcycle tank

I have never seen this and it is not a common problem. Electrolysis is not really a problem on brake system components.

not sure of the cost but try JC Whitney

I agree - I think I would get a second opinion.

Your carbs are dirty and need to be cleaned. A tank of bad gas or old gas can gel up the jets. You buy gas, drive home, and when you get there the bike stops idling. Light gelling can be fixed by draining the carbs (screw on bottom of bowl), pulling the fuel line off the tank, and squirting some motorcycle carburetor cleaner down the fuel line. Plug the fuel line back in turn on the gas and start up the bike. If that doesn't work, using the same procedure buy some Chevron Techron fuels system cleaner, pour directly into the carbs and let sit over night (also drain tank and heavily treat one gallon of gas and put in tank) Fire up bike and let run ,idle, slow drive for 5 to ten minutes. This will usually get cycle idling without disassembling carbs. If it still wont idle you will have to take off the carbs, disassemble and clean blowing through the jets and jet passageways.

The problem with a bike sitting around is that the inside of the tank rusts and the gas drys up leaving a very unwanted residue of varnish in the carbs. The repair is going to be a bit of a project and very frustrating.

Remove and drain the gas tank. Remove the old petcock. Clean the rust out inside of the tank as best you can. Install the new petcock AND install an inline fuel filter.

Next, remove the carbs and disassemble for cleaning. I would spring for carb rebuild kits but only if it looks like the carbs can be saved. Often, abused carbs just need to be trashed and replaced. If you have never balanced and syncronised four carbs you are in for a very frustrating day. I am serious here > keep a fire extinguisher handy.

It's likely that the cost of fixing the bike will be more than the bike is worth, especially if you pay the dealer to do the repair. Your bike is 27 years old and most dealers will not work on anything more than 10 to 15 years old. Parts availability is a problem as well. Even if you get it running, what shape is the gearbox in? Are any of the shift forks bent? Is the clutch operational? This bike is a total shot in the dark and a risky investment at best.

I hate to be the person to tell the bad news but I would hate it more to see you put money and time into lost cause. I have the tools and experiance to fix bikes > I wouldn't want to touch this one. Best wishes anyway.

Please rate this solution as a "FixYa" to the problem if you feel I have answered your question adiquately.
