Noob trying to learn the basics-82 XS400 HS
XS 400 special
Looking for some help...very much an amateur but got up the nerve to clean my carbs. The bike seemed to be suffering from a blockage. I believe only the left side was firing. At first, it ran fine but it had no power, full throttle was a very slow acceleration. The get-up and go, got up and went. Then something changed for the worse and I could get it to idle fine and go, but I would get lurching and then it would die.
The cleaning seemed to go well, sure enough, there was a blockage (a pretty good one) under the right passage below the pin that controls the float. I believe where the fuel passes from the first to the second carb. Also, the little pin holes on the brass tube were blocked up a bit. Carb cleaner seemed to make it through every passage and I think I managed to do a decent job. Though i definitely got carb cleaner on the rubber bits, including the diaphragms.
Anyhow, now the bike seems much better, but even with the idle adjustment screw all the way in, it is just getting to 900-ish revs and dies after a few seconds. If I hold the throttle at 1500-2k it seems to be fine. But at lover revs it sort of chugs every fourth or fifth beat. like I get 4 nice cha-cha-cha's then a longer glug. But as long as I keep it idling slightly higher with the throttle everything seems to be fine. I'm just not sure why the idle screw now seems to be below the height range where I can adjust my idle?
It's like the idle screw got shorter, even with it all the way in/up I'm just at the beginning of the 900 rev range, and that's not enough to keep her going.
Any ideas what I might have done? Any advice would be appreciated.
PS. I'm very new to all this so my terminology might not be up to par....so please feel free to speak to me like a child.
