Really...strange what you need to do is see if the bike is running too fat. So...warm her up witha fresh set of NGK! spark plugs. After the bike is warm take it down the street and back. When your on the way back get on the throttle and accelerate then shut er down and coast it into the garage. This will give an acuurate read on the spark plugs at operating temperature and under a load. Pull all the plugs. If they are brown like coffee with cream that means carbs are adjusted correctly. If they are black and wet too rich and if they are white or very light brown too lean. Other problems may be oil soaked plugs from loose top end parts. Maybe valves or guides.

1989 fzr 600.if i dont start it twice a week when i do go to start it the plugs faul out.i dont leave the gas on .help


are they oil or gas fouled? if oil and high miles, propbably time for a top end rebuild if fuel then you need to rebuild carbs and get the fuel oil mix correct. I had an old triumph that used to foul the plugs with oil, I crossed the plugs to Bosch brand and only had to change them every once in a while.

Bike won't start 92 yamaha fzr 600


Sounds like the plugs are fouled out, I would pull them and make sure they're about the color of a paper bag. If they're all sooty and wet you most likely have a rich condition. I would take the carbs out and clean everything and pop in a new set of plugs. I have a 87 Fz600 that was acting up until I cleaned the carbs.
