how to clean carburetors on a dirt bike?

Question

2 stroke honda XR200R

i've been overseas for 4 years while the bike set...it won't start and it is firing so i assume the carburetors may be gummed up...have no experience on cleaning the carburetor

Answer 1

First off, an XR250R is a 4 stroke.
--Remove the carb from the bike
--Open the float bowl
--Remove the pilot jet (long and skinny). Hold it up to the light. You shoud be able to see through it. Soak it in carb cleaner over night. If you can't get it clear, pull out a strand of wire from a wire brush with a pair of pliars. Then poke that wire through the jet to clear it and soak it again.
--With carb cleaner in a spray can, Spray through every hole in the carb. If the spray comes out a different hole, that circuit is probably clean.
-Remove all gunk in the float bowl.
--Keep carb cleaner away from all rubber and plastic parts. They'll melt.
--Any problems - soak the entire carb in a can (or bucket) of carb cleaner. Wash it completely with water. When finished. blow out all water with compressed air.

Answer 2

Okay, first, the XR200R is a four stroke bike. Now, if the bike has been sitting for years, you'll need to drain the gas, replace it with fresh gas, remove the carb from the bike, and clean out the jets. They will be clogged probably. You can do this with a very fine wire and some Gumout carb & choke cleaner (wear goggles). If you are not mechanically inclined, this is a job for your dealer to do. It is not a job for novices.

Answer 3

The easiest way is to spray carburetor cleaner (Gumout is good) directly into the throat of the the carb while the bike is running. Rev the engine up while you do this, or it will stall.

If your bike isn't running, or the spray job isn't sufficient, you need to take the carb apart and soak individual pieces in a carb cleaning solution.

Answer 4

You can try spraying some carb cleaner into them, but the best bet is to take them off, and soak them.

Answer 5

spray a little carb cleaner while its running.
