What are the float valve specs for my 1992 xr250

Hi.

About the float valve, the float and needle/valve system determines the amount fuel coming into the carburetor chamber. The fuel in the chamber goes later to the jets. All that you have to regulate is the needle height. Regulation can be done according to specs.

Here service manual with specs:Honda XR250R 96-04

or: Honda XR250R 96-04

If they do not work, use: Honda XR250R 96-04

Here a link showing pictures and steps of float regulation.

Once you are in the float chamber, check the valve, clean the chamber and the valve system.

The valve sometimes can become sticky, particularly if the bike has been left standing for a while. To do maintenance on the valve, remove the carb cover and lift the float gently, ensuring that the needle is free to move without sticking.To clean the system, take out the float pin, remove float and needle and spray carb cleaner using a pad to clean needle and the seat. When you reinstall, be sure that the needle pin is shaped correctly and sitting properly in the carb.

Here an exploded of the carb, click on the picture to enlarge:



Near to the needle, in the float chamber there are the jet valves. These can be adjusted using a special wrench tool. If you do not have the tool, the screw can be turned into a regular screw by using a mini-saw to cut a line in the middle of the screw head
