Not So Lazy Man's Teikei (TK) Carb Cleaning
Not So Lazy Man's Teikei (TK) CV Carb Cleaning (2001 and newer TW's)
(EDITED 8-4-17)
After 10 years of cleaning and rebuilding TK carbs, I find that if you want to do it right, the carb should be removed from the bike and thoroughly cleaned.
***If your bike has been sitting for month's or years, the carburetor needs to be removed completely, and thoroughly cleaned.***
This procedure is for informational purposes only.
Proceed at your own risk.
If you are at all hesitant, take your carb to a Yamaha shop to be cleaned, about $70. plus parts, the last time I checked (prices vary widely). This was the price I was quoted if you remove the carb yourself and bring it to the shop (in 2007).
New carbs are expensive... about $275. US.
Internal parts are small and easily lost. It will take time and money to replace them.
The carb will not work property, or at all, with missing parts.
There are good instructions and parts diagrams in the '01 Supplement Manual, p 32 to 39.
'01 and newer supplement
I am not a professional mechanic, only a reluctant one.
You may be able to proceed without removing these parts but it makes it easier to get to the carb.
Remove seat.
Remove side panels
Turn off petcock.
Remove fuel line from carb.
Remove tank.
Open drain screw and drain gas from bowl.

Loosen hose clamps.

On the right side of the bike:
Look at position of the throttle cable retaining nuts.
You will need to put them back when putting things back together.
Take a picture.

Remove throttle cable locking nuts.
Remove cables from bracket.
Remove cable ends from pulley.

Rotate carb to the right 90 degrees

You now have access to the bottom of the carb.
Remove 4 float bowl screws.
Remove float bowl.

With the carb in this position, you can access the pilot jet and main jet, and check the position of the pilot screw.
From the other side of the bike, you can access the vacuum chamber.
To Remove the Carb:
Grab the carb and push it towards the airbox until the front to the carb comes out of the engine mainifold.
Then angle the front of the carb towards you, and wiggle it out.
It's not easy, especially if you have an old hardened rubber boot on the airbox.
Some people prefer to unbolt the 2 bolts on the manifold and remove the carb and manifold together....whichever is easier for you.
