and a few spare parts. Cleaning tank...rust remover..adding red kote to slow down the rust buildup, adding fuel filter to help.
Looking for tutorial on how to remove carburetor to begin the journey.
I have read a bunch of your threads in the past and they have given me a confident backbone to tackle this stuff.
Looking forward to hearing from the forum.

Thank

welcome to the site, I also have an 83 and couldn't believe how hard it was to get the carbs off! I was in the garage for way too long, considering it's only 4 bolts and then the air box!
Does Yamaha have some special tool for this? Normal Allen wrenches are way too big for that job.

Honestly, I wouldnt even bother coating the gas tank. Ive heard horror stories about peeling.. Ive never coated any tanks. People do it succesfully all the time though. Get a jug of vinegar and a tube of pellets/BBs. Let it sit and shake it around for a couple days and drain it. Do that once or twice until the vinegar is reasonably clean. If you leave the vinegar in too long, it will eat into the metal and may expose a leak. Then you will have to strip the tank clean and start soldering holes. I have some surface rust in my tank, I run a clear sintered brass external filter so I can visually see what the fuel looks like. I clean my carbs at least once a season and theres never any sediment in the bowls.

When I store the bike for winter, I drain the fuel and spray fogging oil in the tank, the tank comes inside with me. I removed the fuel bowls and spray them with fogging oil and they will also come inside with me.

The carbs are easy to remove, just may be difficult to get to.

Gas tank removed. Remove the filters and the H-pipe from the carb and loosen the clamps on the boots. Pull the throttle cable straight up and release it from the throttle linkage. Then you just push the carbs down and out of the boots. Then the carbs can be persuaded to be removed on the left/right side of the bike

Cleaning carbs is definitely the most difficult procedure without getting into engine work. Carbs have very small parts and can easily be lost, stripped, and marred. Keep the small parts matched to its corresponding carb body, do not mix them, especially the slides.
