One carb overflowing- wat do?

Post by garrett »

My FZR750 has been running fine since I douched out the carbs but I started it up today and noticed it was misfiring on cylinder one. Got cylinder one figured out and then noticed it was overflowing between carbs 1 and 2. I ran them dry and have parked it for the night.
What should I check?

Thanks

Sounds like the carb needle and/or seat in bad/worn, and I would do a full tear down and rebuild, good kits are available below as well as other items for your bike.

Drop the bowls from the carbs and check the float and needle valve - chances are that it is sticking due to some old gas or tiny debris.

You can also replace the individual needle valves or do the full kit depending on when the last carb rebuild was completed.

Tapped the bowls with a screw driver and now it's not leaking.
