5. I rebuilt the carbs with viton O-rings on the accelerator pump, new paper
gaskets on the slide towers etc. I don't think there's an air leak in the
towers.

I put a light coat of grease on this paper gasket before installing. That
way you know it will seal good. Give it a try.

 Charlie et al,

They are the square carbs VHB 29s. Here's what I tried so far:

1. Tried switching the slides around but they really only seem to go one
way, big side toward engine, as the top adjustment screw hits the body of
the slide when I install it other way around.

2. Tried dropping the slide needles to their lowest point so that it would
let in as little fuel as possible. Also, tried middle and top settings and
bike still ideled real fast.

3. Checked to be sure the enrichers (chokes) were really pressing down on
the bottoms of their repective seats. Cables were nice and slack.

4. I put high-temp silicone on both sides of the head gasket before
assembly. Also, put silicone on the hex nuts and on the fiber washers of
the
 intake tubes.

5. I rebuilt the carbs with viton O-rings on the accelerator pump, new
paper
 gaskets on the slide towers etc. I don't think there's an air leak in the
towers.

6. I checked for air leaks in the intake tubes by spraying starting fluid
on them while bike was idling and it didn't rev any higher, that I
noticed.
 
7. Ian said to check to see that I didn't inadvertantly put the main jet
on
 the accelerator pump and vice versa. I can't imagine making such a rookie
error but I will check that.

8. Just tonight I was gooping more silicone near the clamps that connect
the carb to the intake tubes just in case there is enough air leak to make
her rev but not noticeable when I spray the starting fluid.

That about covers it. Any suggestions are appreciated. Bob

Hi Bob,
I can't remember, does your bike have the old Dellorto SS1 carbs (round
slide vs. square, detachable float bowl assy.)? Just thought we should be
sure of what carbs we're dealing with! Cheers,

Charlie

 "There's a lip on the slide that fits into a
groove in the bottom of the carb. I took a look in
the manual and I did
install the slides correctly (I think). Bob"

Bob, my version of the manual has the slides pictured
backwards! Maybe yours does to. And the throttle stop
screw screws OUT to lower the idle, not in.

Keith, I think my manual recommends 10w oil, which is
what I was using until several people recommended I go
to 20w to get some damping out of a very lightly
damped fork design. I can't tell the difference, but I
am using BelRay 20w now. The weight of your oil won't
effect how low the bike sits on the fork, as far as I
can see, but I agree with Charlie that heavier oil
makes more sense of you then lighter, as it may lesson
the chance of toping out after rebounding.

It's been a while since I took my forks apart, so I'll
let someone else answer that question.
