Washers under the needles has usually been reported as having little to no effect on the 700S.

I've never owned a 700S. I looked it up and the 700 does call for the washer and 1 step richer main unless you're otherwise not stock and not at high elevation.

I did a 250 NH, 92 750 NH, and a 98 CBR1100XX. All with great results!

Based on advice from the old forum, I put 2 very thin washers under my needles 11 years ago (late model NH 750).
The change was negligible - BUT WHEN I PUT IN BIGGER JETS this year, along with the washers, the behavior beyond 5,000 RPM to redline was amazing.

My bike was never really happy above 5,000 and it was time to shift gears.

After the suggested settings from carbjetkits.com I went for a test ride, gunned it, my clutch slipped and I nearly Sh*t my pants.
So I don't think the washer "alone" is going to do much. But with proper jet (not emission restricted), new plugs and air filter it all works together.

That's the downside - may need to replace the clutch like I had to.

I too have used the carbjetkits parts, and the "cold bloodness" that everyone seems to experience with stock Honda's is gone. I didn't drill or do any other irreversible nonsense to any parts, and all parts supplied were original Keihin.

Gotta love them tits.  Wait, what?

Oh yeah.  The bad running continues with the FI bikes today. Have to get an ECU flash to get the power and get rid of the throttle jerkiness.  Thanks CARB and EPA. Much more $$$ than jet kits.

I'm just finishing watching the last clip from the video tutorial Bob recommended (thanks for that) 👍

I did learn a few things, not much, but like rounding off the tab for the mixture screws is a good idea, and how he holds the diaphragm up while putting on the carb tops is also a good tip.

The best education I had was hands on taking them apart. 

I'll be doing some spraying over the coming days and keep y'all posted with some lovely pics.
