The bike i have has been sitting for about 2 years in the garage and the gas tank is rusted inside brought a new tank it was running fine before it was parked want to know what should i do before i put the new tank on and attempt to start it

Probably 2 year old gas in other tank. switch back to the good tank and run injector cleaner for at least 2 tanks of gas.

battery up to parr? try new sparkplug,does this bike have new igniter pac,?check voltage at coil,etc at coil,points..are points grounded?

What is wrong with the tank?? Rust? If not, the same gunk in the tank is in the carbs, They need to be cleaned too. If it is rust, you can clean and seal the tank like new again, with a little elbow grease and a product called POR, (paint over rust), It works great. leaves the tank looking like brand new inside, if it is gummed up from sitting, you will need to soak everything in carb cleaner, and scrub and clean and scrub and rub and wipe and pick out gunk till it is squeaky clean. Then maybe it will run. The jets in the carbs are super sensitive, the slightest spec of dirt or the tiniest clog, it will not run right. Check it out, hope this helps.

If is runs better with full choke, then the bike is lean, check for air leaks at the carb manifold, vacumn cracked hoses, non standard exhausts, perhaps the mufflers have rusted out while sitting

Electrical won't be your biggest problem. Pull the carbs off and start crying now. 5 years of sitting killed them dead. Carb rebuilding or replacement, gas tank sealing, new battery, tank lock repair, oil change, spark plugs, rotted tires replacement (yes they are) and the electric issues will be or exceed your sanity level and value of bike. Sell bike now get a newer one that runs. You'll thank me later.

I hope it was sitting inside and not outside. Bear in mind this bike may get costly. The following are general thoughts

• Remove the bike battery and run jumper cables to the battery leads. Will the bike turn over using a car's battery?
• Do the clutch and throttle cables work okay?
• With car battery hooked up, does it have spark?
• Shoot WD40 into each cylinder to lube the rings
• Change gearbox oil. Lube the chain. Be sure the brakes are functioning properly.
• Chances are the carbs are gummed up and will need some serious cleaning. Add an in-line fuel filter.

How bad is the rust inside the gas tank? You may need to seal the tank with KREEM to kill the rust problem.

• New chain. New front and rear sprockets (if needed)
• Battery
• Carb rebuild kits (if needed)
• Upholstery
• Tires
• Throttle, clutch and front brake cables
• Speedometer cable
• Electric starter (if needed)

If your bike has been sitting for that long with gasoline in the fuel tank and carb, you can be sure that you need to have the carb disassembled, cleaned, and put back together. Pay particular attention to the accelerator pump diaghragm.

I'd also take the tank off and empty any old gas that was left in there as well. Inspect it for rust on the inside. If everything looks pretty decent, reinstall the tank and fill with fuel. Remove the petcock and clean the strainer on the inside of the tank.

There may not be an in-line fuel filter on the bike. Most bikes don't come with them. Yes, the fuel petcock has two screen filters on one pipe and they can get clogged up. Remove the tank then remove the petcock and clean it. The gas in the tank should be dumped into a clear plastic storage bin so that you can see if there is any water in the gas as well as rust and trash. Your bike is 15 years old and the inside of the tank may be rusty. If so, Google “ kreem fuel tank liner “ or go to

This will end the rust problem. Go ahead an install an in-line fuel filter. There is a drain plug on the lower left side of each carb. Drain each carb into a clear container and look for water and trash. You may need to clean the carbs but hold off to see if the other stuff fixes the problem.

Go to the site below where you can see a parts diagram for your specific bike. You will select the actual brand, year, model, etc., once you go to the site. Part numbers and prices are also shown. You can order parts from this site. In the event no price is shown on a particular part, the part is not in stock.

After sitting 2 years, there must have been some fuel in tank that has probably gone real bad (like shellac) and contaminated the fuel system, plugged up filter etc. Usually rust will form in tank, mixed with stale fuel, it will turn just like mud.

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.
