Hello again.
!982 GS 850G. I should have never let this thing sit! Got it runnig at idle, great, then wouldn't go much over 45, it literally ran out of gas, or felt like it. Still an air problem, or a gummed up petcock. Pulled and checked petcock, clean, flow is apropriate. Next down the line Vacuum. Surely this 38 year old line wouldn't be leaking...replaced. Replaced one side of the airbox seal, the access for the filter. The other side seemed okay, and this may be a problem, I didn't change it. As far as the drain hose on the left side I replaced it, used part of the old hose to fit in the airbox, nice tight fit.
Went for a nice, 100 mile ride yesterday! As long as it was flat and the engine required no real load it ran beautiful. However the test was the 12 mile 65mph hill out of Bullhead City coming home. She would pull at 55, so 1/4 throttleish. Ask more than that and forget it, 65, pushing half throttle, it would run but not smooth. Pulled plugs, looked okay, but I stupidly started it this morning before that. Pulled carbs, I thought there may be crud in the needle jet bores, nope clean. I did notice the tops of 3 needle jets were wet. Now when I put these together I heed the warning about soft brass and stripping so I did not or haven't bee gorilla tightening them. Today I did indeed go tighter, seat the jet, and 1/4 turn or so. I am thinking you have have some tightness to pull the needle jet down and seat it in the carb body. Maybe I was too loose before and there was a leak? Yes I will seal the other side of the airbox.
I took a hose (no not a compressor, lung power) and blew in to the passage for the slides, just enough to raise them to the top. All went up and back down. Three of them are original, one is 10 years old, as well as the 3 spares in my tool box. No holes but you can tell they are old. I am saving these expensive pieces for a failure. If the old ones ain't broke, why replace them? Or am I being cheap and foolish. I know one day they will become Unobtainium.
When I checked the petcock I applied constant vacuum, gas flowed nice. But I notice the engine applies vacuum at a pulse, could there be an internal petcock failure I am not picking up? I did see if it would leak down when I had it off and was checking the 38 year old vacuum line for leaks (it did leak either but got replaced).
Thanks
