The reason for doing the bench sync is to allow the engine to run with a reasonable idle to allow the guages to fine tune the sync setting.

If your bike will fire up and run, hook the guages up and go to it!

 

No.
You don't have to Bench Sync them ... It just helps get things going.
Get it running a little bit before you hook-up the sticks.
You might have to do some experimental tweaking to find a spot where it will go.

After you get it going ... hook-up the sticks and start dialing her in.
Bang-out a quick ... ballpark setting ... to get it close and keep it running.
Increase Idle by using the Manual Idle Rod to open #-3
Look at your sticks and bring-up (or down) any one way off.

Then, do the sync right.

Adjust:

#-1 -- to -- #-2 [Adjust the sync screw of #-1]

#-4 -- to -- #-3 [#-4 Screw ~~ #-3 Has NO adjustment screw]

#-2 -- to -- #-3 [Adjust #-2 Screw ~~ #-1 is attached to #-2 and is adjusted along with it.]

YICS

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!

Good Luck

 

Nice thinking on that improvised YICS tool Rick!!
Wish I had seen a post on it before I built my own... Oh Well!

Still good work there!
