OK ... let's just hop down to the Bottom Line.

Here's your own personal, handy and disposable YICS TOOL.

I don't care what Material or Lubricating Agent or what variation you might add to make this different in any way ... the concept is mine. Therefore, I am naming The Concept.

"RickCoMatic's YICS Stuff" (and a better name to be added later)!

Sharp hook the end of a length of wire coat hanger.
Snag the well-trimmed end of a length of COTTON Clothes Line to the wire.
Wrap the splice with a bit of DUCT TAPE to prevent the Clothes Line from coming off the wire.
Undo BOTH Caps on the openings to the YICS PASSAGE.
Pass the wire through the passage and prepare to draw the Clothes Line through the YICS Passage.

After the splice and taped end are started-in ... begin saturating the Cotton Clothes Line with MARVEL MYSTERY OIL. (MMO)
As a cleaner, a fire-proof agent, top cylinder lube and most importantly ...
A VAPOR BARRIER!

Pull the MMO saturated clothes line through the opposite side.
Leave several inches exposed.
Cut.
Stuff the MMO saturated clothes line back in the YICS PORT and replace end PLUG.
Stuff the open side with MMO saturated clothes line.
Replace plug.

Balance Carbs.
Set Mixtures.

Remove "The RickCoMatic Stuff"

I'll come-up with a better name for it later.
Cheap.
Clean.
Safe.
And good for your engine!

Just use a real long NARROW strip of T-Shirt tightly knotted together.
No muss.
No fuss.

May 2012 Update;

Since this was first published I have had a great number of people PM me with "Refinements"
This one was best.

Ricko. Just cut-off the bottom hem. Start cutting again and don't stop keeping the with a half inch until you hit the neck! No nots.

 

rick massey,your a gem,what a great idea that is,,this is why i joined this club im 59 yrs old been riding since i was 14 i had to laugh at my avitar as it says wantabee hmmmmmmmm interesting ,,laughed alot as you can imagine,,anyway back to the yics i did make the one in the diagram,just finished it ,,then read your reply,havnt tried it as of yet,,silly question in australia i dont think that the oil you mentioned is available here,,can you advise me if a substitute oil can be used for this process,,im a little concerned to use just any oil because im thinking that instead of cleaning the passages i might end up plugging them as you can imagine,,could be a problem in the making lol,,,once again thanx so much for your tip looking forward to hearing from you again wilfred

 

You can use motor oil too.

Even when using a proper reproduction tool, it should get slathered in oil before deploying it.

 

You can use any Commercial Top Cylinder Lube.
LUCAS comes to mind.

Cleaning the Passage is simple.
Remove the Plugs on both sides.
Fashion a Ram-rod from Fiberglass Driveway Marking Rod.
Drive "Patches" of Terrycloth (4.5 sq cm +/-) saturated with Carb Cleaner through the Passage.

Continue until one come-out as clean as it went in.

Cleaning the Orifices can be done with a Tool fabricated from a Wire Coat Hanger.
Place a Right Angle on the Wire that will fit the Tunnel.
DRESS the Right Angle with 800 Finishing Paper so it will not snag an O-ring
Probe the Orifices.

FLUSH:
With one end of the YICS Passage Closed with its Plug.
Rubber Stopper the end to be opened for a Running Flush.
IDLE the Bike.

Tape a Carb Cleaner Tube to your Thumb so it will not be sucked-in to the Tunnel.
Have an assistant remove the Stopper.
Quickly cover the Passage with your Thumb --> Inserting the Tube into the Passage.

Shoot Carb Cleaner into the Passage.

Short bursts of Cleaner.
Let rpm's fall.
Repeat applications of SHORT BURSTS of Cleaner.

It's important to attend to details.
Before you start any "Tuning" assure that the valves are within specs.

The most important word of advice I have to offer is:
Get yourself a Genuine Yamaha Workshop Manual -- specific to your Bike.
