Question about 1991 Yamaha FZR 600
Last year i had a bad ground, i fried my cdi box, and only had spark on 2 wires. yesterday i got that cdi box, and now i have spark on all 4 but it still wont run, i changed staterz, coils, changed my oil and filter. its getting gas cause i can smell it. i put gas down the carbs, still wont run.
How long did you let it sit for with gas in the carbs, you may have clogged up your jets. after awile gas will break down and turn into varnish, if your bike trys to push the varnish through the system it will clog the jets. try to take off your seat then remove your plastic over the gas tank. remove the gas tank and you will see four bowls *silver ones right next to where the gas tank is on the carbs*. your bowls are in sets of two. there are drain screws on the bowls to remove the gas inside. remove the 16 screws holding the bowl onto the carb. *4 on each* inside you will see your floats and jets. carefully loosen the jets with a screw driver then finish unscrewing them by hand, they are brass and very soft. you should be able to hold up the jets to the light and see a small pin hole. if not get some carb cleaner and give them a squirt and blow them out. do not try to use anything to clean them out, they are very very sensitive and one knick will change the jet. after that i would spray some carb cleaner up the jet holes and try to clean them out also. if you have a compressor it would be wise to use that to blow out the gunk from the jet holes as well. after you run threw all 8 jets put them back together and see how it goes, if nothing you may have to check the jets again and if clogged again your carbs are gunked up and will need to be cleaned
