Video of issue with low revs
« on: June 16, 2019, 11:18:24 pm »
Still hunting for issue of low revs issues. Checked plug wires and caps. Seem to be tight.
Pulled carbs, checked diaphragms and all good w/ no tears, holes or issues.
Cleaned carbs again to check pilot jets were clean. Found one tip missing on pilot air screw. Replaced all 4 and adjusted to 2 turns out. Checked float level and all @ 17 mm at 45% angle. All per shop manual.
Still getting slight smoke out exhaust that smells like gas. Never did that before :-[

Emailed SISF a week ago about carb service but have not heard back. Don’t know if he is still doing C-10 carbs or still unpacking. I know moving is a bear.

Thanks

1-1/4-1-1/2 turns out are what I've seen on stock Concours.

I have done tons of searching for carb info lately. The most common number of turns for the pilot screw from what I saw was 1.5 to 2 turns. I wrote this down in my notes, think Steve S. said it: "Set carbs pilot screw to 2 turns out and forget it."

EDIT: Service manual says 1-1/2 turns.

Your idle is good. It burped a little around 600 rpm. Is that what you are talking about?

The concern is when it gets to the 2000 RPM’s and hits a wall.
Should be able to keep climbing but doesn’t. With the slight smoke and all, I’m thinking of pulling the valve cover and checking the valve specs again.
I only really did 3 things to the motor.
Valve adjustment, exhaust sprocket install and carb cleaning.
My thinking it has to be one of these three or....
Still keeping the faith as I know what she is capable of :motonoises:

If you are running poorly at higher RPM, that sounds the opposite of problems with pilot jets. So many thing could make it fall flat as RPM increases.

what screws did you use? OEM Kaw, or the K&L "kits"..?

also, did you make sure to account for the flat washer and o-ring, under the spring, on each needle screw? jussssst checking...

K& L kits have a slightly longer/and gentle taper, and often as I have found, actually respond best at 2 to 2-1/2 turns out..
