Not really UNDERSTANDING ALL THE CAPS, but I am pretty sure its not an o-ring. its about a 1/4 inch thick, plastic and sits under the notches on the slide needle inside the slide. I am not making this up, there is a plastic ring (plastic not rubber like an o-ring) under the notches on the slide needle that seats inside the slide. There is no disrespect meant in this post, just trying to clarify. I am talking about the inside of the slide, not the screw on the outside of the carb.
Ooops. Yep, wrong carb. Glad I don't have one of those. Threw one from my old Suzuki in the trash.
tooseeveeJust about every carb has it's lovers and haters. Many HD owners think the CV is the bomb. I'm just too wed to Mikuni. I didn't care much for the Carter on my Sportster either! ;-)
1/4 throttle responsiveness. I've had the same issue. Drop the needle one notch richer. That plastic washer will spin and then you can push it anyway you want. It moves once you free it up. Also, our UK brothers have shaved about .7mm off the bottom of the slide allowing a richer condition which may solve the slow to return to idle condition. I'm running a 17.5 pilot, 120 main now , richest notch, about 1/2 turn on the mixture screw.
...........But don't you mean raise the needle a notch richer, not drop the needle a notch richer?Just askin'. Also, could you discuss a little how shaving the bottom of the slide richens the mixture? I can't see it in my head.
Hope the rain stopped. It's beautiful by me and I'm out the door soon to ride!I'm not a slide expert by any means, but Scottie said it. By shaving the bottom our our BS29 slide, we reduce the size of the cutout thereby richening things up. The combo between slide and needle really effect that 1/8 to 1/4 throttle response I believe. I always get by terms mixed up on the needle notches. Scottie's explanation is what I meant to say, but he's done a much better job.
Excellent! Sounds like your very close. I find can't leave mine alone
How many turns out on the mixture screw? How many did you start @?
