bike sat for two months-now runs crappy

Recommended Posts

My xr400 has been parked for two months-ran fine before I parked it. Now it will start and idle okay but from 1/4 throttle on it seems to be real "blubbery" and rich. Anyone have an idea what happened? :cry: :cry:

your carb is gummed up. next time drain your gas before you let it sit up that long. you need to take the carb off the bike, take the bowl off and clean every hole, crevace, crack, etc. and all should be well. be sure to clean out the jets really well too. run a piece of wire through them to make sure they are clear. good luck!

Do not run wire through the jets! Their diameters are critical. Take them out of the carb and clean them with carb cleaner and compressed air.

Exactly right.
