As the bike was not used for years, the jets in the carb may be clogged or rusted. Please replace the jets. These jets can only be forced by choke to let fuel go and not otherwise. Changing them will rectify the problem.

    i cleaned the jets and every bit of the carbs. could that still be the problem?

    James,

    The role os choke is to supply more fuel at the cost of air. Your bike runs on choke, which means that normally there is no fuel reaching the carb. It could be the jets or the pet ****. Try the petcock to ensure that fuel is indeed coming from the fuel tank. If yes then the jets need to be changed. Else the petcock needs to be changed/cleaned.

Yamaha FZR 600 not charging correctly with the lights on


I HAD THE SAME ISSUE. CHECK YOUR VOLTAGE OFF O THE MAGNETO, IT SHOULD BE IN THE 25V RANGE. IF THAT CHECKS OUT OK CK THE VOLTAGE IMEDIATLY AFTER THE VOLTAGE REGULATOR, I BET IT IS BELOW 14V. THE FZR IS PRONE TO HAVING THE REGULATOR GO BAD (THE OLDER ONES HAVE NO COOLING FINS AND THEY BURN THEMSELVES UP). THE BEST ONE TO BUY IS THE NEWER VERSION FROM A 1999 FZR, IT HAS COOLING FINS WHICH GREATLY PROLONGS THE LIFE. YOU HAVE TO DO SOME SLIGHT WIRING MODS, BUT NOTHING ANYONE COULDN'T DO. SEARCH FOR FZR REGULATOR UPGRADE AND IT WILL EXPLAIN EVERYTHING! I HOPE THIS HELPS! GOOD LUCK!
