Motorcycle Repair: Fuel Mixture for a 1976 tl 250 honda, air fuel mixture, air screw

Question
What is the fuel mixture?

Answer
JJ,

if you are asking about the adjustment for
air/fuel mixture on the carburetor,
you just adjust to get the smoothest
idle by turning the pilot air screw.
-Start with it about 1.5 turns out from
lightly seated.

-the engine is a four-stroke which requires
no other mixing of fuel/oil etc.
-Gas goes in the gas tank and oil goes
in the crankcase up to the proper
level. It will have a dipstick
or site glass to check the oil level.
(10W40 four cycle motorcycle oil)

-let me know if you need other info and

The XL250 engine is almost identical to the
TL250. Most parts will fit.
