Question about 1985 Yamaha XJ 700 X Maxim

1 Answer

1985 yamaha Maxim 700 carbs gummed up.

I went through the carbs but left them on the rack. Should I have taken them off and cleaned the stuff in between also? The tank is terrible! Somebody didn't clean it correctly before doing the tank coating inside for rust so now I have rust and coating falling off. The carbs I'm not sure how to set the floats to make sure they are all the same and don't want to have to synchronize them again. I have a good running Honda for transport but no way to get this 12 miles to a repair shop. I bought crappy kits and couldn't do a good carb rebuild. They didn't give you all the same parts that came with it originally. The float valves don't have the screen like the originals and got a little piece of aluminum or something to go somewhere but don't see where. Lol I need help. Please!!

You can leave them together as long as the choke circuits are working. Leave the floats alone, as they are probably set correctly. The little aluminum plugs are for the A/F screws. If you haven't taken them out, then they are still in place. If you have, leave them out as you don't need them. They are for the EPA. If your tank is that bad, find one that is good, and trash the old one. It will save you from having to keep taking the carbs off over and over, then you will have wished you had gotten another tank. If your new float valves don't have a screen, get an inline fuel filter which would be recommended any way. One for a lawn mower should work great.

If I understand "the petcock was in prime position and it eventually quit dripping."
Prime = on
Sound like the needle rubber was hard and after a while they soften up enough to cut off the fuel.
Keep an eye on it and ride safe.

Carburetor on yamaha xj700 maxim x


Actually, they're not Hitachi carbs. Since you have a 1985 "Maxim-X", the model number is actually XJ700XN. The XJ700 does indeed have Hitachi carbs but your bike, the XJ700XN Maxim-X has BS33 Mikuni carbs.

Careful with the model number, the XJ700 and the XJ700X are entirely different bikes.

By the way, if you want more answers about your Maxim-X, feel free to visit the "Maximum Maxim-X" web site at www.maxim-x.com and the lesser known FTP site for the Maximum Maxim-X web site at www.maxim-x.com/pix

1985 Yamaha XJ700 Maxim won't work


All engines need the same three to four things to work correctly..
Compression, Fuel, Spark, (timing).... But, usually those bikes, have fuel issues. The fuel tank spigot has a vacuum controlled valve which when the engine is cranked, suction is applied and fuel then can flow. Second,, the needle and float in the carb tend to get gummed up along with the main and idle jet... You need to make sure the carb is maticulously clean, Using carb cleaner, and tag wire,, or a piece of fine wire ( be careful not to enlarge the tiny holes). Keep refering to the 3-4 list fuel, compression, Spark,,,timing.....
Good luck...!!
