Exclamation Ditto

On removing the A/I. The screws are under the carbs in front of the heaters. They are a D screw. I opened mine 1/2 turn as recommended here & it smoothed things out nicely. DX THE A/I 1st!!

Here's a link to a bottom view picture of a Keihin CVK40 carb. Click on the link, the pic is bigger than the attachment view.
