Needles are tied directly to the slide. I figured in the lowest position of the common throttle position, if the needle can drop any further then less fuel can go through the primary jet. I’ll start it tomorrow and find out I guess. If that doesn’t work then I’ll change the idle and primary jets as it can’t be anything else. Also should be noted that I have no throttle cable connected to the carbs yet so that isn’t a factor. Not sure what you mean by the fast idle? The idle screw adjustments? They don’t change the rpm much if anything noticeable at 4000 rpm. I’ve tried all the way in and all the way out with no real changeSlides are closed at idle, needle height won't have any effect.
Sounds like fast idle needs adjusted.
I was just going off of your earlier statement.Bike runs but idles way too high when warm.
Thanks for the solid info. You got this my man.Needles are tied directly to the slide.
I mean "fast idle." The screw adjustment designed to lift the slides and make it idle at a faster rate (3500 - 4500rpm) rather than 1200rpm, actuated by the choke lever...Is it adjusted properly? 0.3mm gapNot sure what you mean by the fast idle?
Alos Stubsryan, this reads like you may have been mistakenly adjusting the Air/Fuel mix. A good starting point for these carbs on the 400four is 1-1/2 turns out from fully seated. Though I have zero 350four tune up experience, I imagine its close to the same. Dont need your machine to overheat during idle.The idle screw adjustments?
