Ninja 250 having issues starting after heavy rain
My 2006 Ninja 250 fell in heavy rain overnight (no cover).
I noticed in the morning and stood it up and let it sit for a day. Then I started it up and it idled fine w/o choke. The next day I went to start it again and it died when I turned off the choke. I was able to get it started with throttle and choke but it dies as soon as I stop applying throttle. After this, I noticed white smoke from the left exhaust and very faint white smoke from the right exhaust and smelled gasoline. I checked the carbs and the right carb float bowl had no fuel and the left carb did. Fuel is being pulled from the tank but doesn't fill the right carb bowl. I thought it could be a clogged fuel line and somehow rain caused the issue. Any advice? I cleaned the carbs about a week ago. |

Sounds like the float valve is stuck. Try tapping on the float bowl until gas comes out drain the screw.

I also noticed the white smoke switch to the right exhaust and then stop after letting it idle. When I cleaned the carbs a week ago I confirmed there was fuel flowing into both carbs. |

check right float-valve.
Only thing that prevent carb from filling. Not tank or petcock issue since petrol is making it to fuel-rail and filling left carb. Unless there's some obstruction in fuel-rail between fuel-rail between left & right ends. Did you scrub out fuel-rail and replace O-rings? Did you replace float-valve and clean valve-seat when doing carbs? Did you completely disassemble carb to every last nut, bolt & individual component to clean? Did you scrub out all secret hidden passages with brushes and PEA-based fuel-system cleaner? http://n4mwd.blogspot.com/2013/10/se...-passages.html Scrub-brushes from Amazon: https://www.amazon.com/dp/B01N6QEINN Disassemble emulsion tubes and poke out all bleed holes in carb-venturi, jets with matching gauge soft copper wire? Ultrasonic soak and micro soda-blast everything? Replace all rubbers: float-valves, float-bowl seals, fuel-rail O-rings, pilot-screw O-rings, even slide diaphragms if needed? Set float-levels with wet-test verification? Sync carbs with manometer? Might as well do all of these skipped items this next time around. If any of them skipped, they will cause you problems in future, requiring yet another disassembly for deeper restoration work. Last futzed with by DannoXYZ; August 27th, 2023 at 03:14 PM. |

"but the right carb still doesn't have any fuel coming out of the drain"
Could it be possible the drain in your RH bowl be clogged?

Good idea to try and dismiss/eliminate simpler stuff first.
