1989 Yamaha FZR 600 - Answered Questions & Fixed issues

If it won't charge on a battery charger it may need electrolytes or the battery is shot. If the bike won't maintain a charge it could be the voltage regulator or the generator stator.

If your driving and it gets warmed up and shuts off and wont restart it may be a float problem in your carbs. The float needle will get corroded and let gas constantly flow while the bike is on and while you try to start it after it cools you burn the extra gas seeming.like it only starts cold. Ive had personal experience here. New float needles.

This problem normally only occurs when the clutch cable needs to be shortened to very littleplay at the lever.If you've lots of free travel in the lever,clutch pack is too tight and shift is hard.I'm sure you know that.Anyway,since is still a problem,I'd be checking the throut at clutch pack before replacing the clutch.Throught lever could be bent or out of position,or just worn out from playing hard.You know how we are.

The fuel pump relay should be mounted along left side of the frame above the rear tire. You will have to remove the seat and faring to get to it.

check the oil level and make sure its not over full. the hose with the mini filter is a crankcase breather, if there is too much oil, it could cause oil to flow out the breather. It is possible that the rings are worn or broken causing blow by or extra crank case pressure. The hard shifting is usually caused by a dragging clutch or the clutch being out of adjustment.

Hello mike, first check all the fuses, make sure none are blown. Check the kill & safety switches. Clean the contacts on the starter button. These are the basics. I hope this helps.

Too much fuel is getting through the carbs. The carbs either need setting up properly or the correct size jets refitting.

No, you do not need to mix the gas and oil because it is a 4-stroke engine and has separate compartments for oil and gas. The only time you would need to mix oil and gas is for 2-stroke engines. I’m happy to help further over the phone at https://www.6ya.com/expert/zamaar_e361c354500963e1

you need to clean or change your spark plugs that is the problem

i think your piston crack already or you didnt change the spark plug.

One or more cells are short circuited resulting a loss of voltage. The voltage is not enough for the bike to function properly. Only one solution: change battery.

Sounds like you need to clean the carburetors.

Take them off and take them apart. You cannot clean them on the bike.

It may be as high as 70vac but at least 50vac test across each combination of the 3 wires, and non should have continuity to earth
