help with idle adjustment
cmotodad:
How much do you need to adjust the throttle cable? Quite a bit? Just a little? Did you pull the idle adjustment screw to check the length? Maybe worn or tip damaged.
bjohn07:
quite a bit. once i adjust it to where it needs to be to keep the bike at an idle the cable adjuster screw is prob 3/4 the way or a little more out. yes i unscrewed the idle screw all the way to look at it. didnt measure. but the tip is nice and pointy, not flat or rounded. what is the length suppossed to be on that? i did notice that when i let the bike run with the choke on, once it is a little warm after about 3 minutes or so i dont need to mess with the throttle any more to keep it going. as long as the choke is on the bike idles but high. around 1600-1800. ( the throttle cable adjuster was turned in all the way at this time so im sure that it had no effect on this)
cmotodad:
Sounds like it could be lean on the pilot if it idles with the choke. How does it run off idle under load? Does it bog or hesitate then pick up rpm's?

off idle under load? as in taking off outa first? it hesitates a little bit. im just going off sound of engine but id say its from 1400-1800 and then it smooths out.

I would try a richer pilot jet. It does not gurgle and feel like it wants to load up, right?
