Hi all,
Ok here's the deal. I was originally thinking that the problem my 81 GS850G has was fuel related. I went through the carbs and made sure float height was in spec, no holes or tears in the diaphrams, and that their general condition was clean. The next thing was the petcock. I found gas in the vacuum tube. I went ahead and eliminated the vacuum according to posts from this site. I now have RES ON and OFF(which was PRI). I have adjusted the valves and syncd the carbs 3 separate times ( adult ADHD). However the bikes starts to break down like it's running out of gas when the throttle is open 1/8 or less. It's most noticeable at 50 - 55 mph. The bike starts fine, idles good, and when the throttle is opened past the 1/8 mark it stumbles for a second then pulls like a freight train. I have been playing with the mixture screws to find out where it runs better. Right now they are set at 2-3/4 turns out. The bike also has new plugs, UNI foam air filter, and new air box gaskets, boots, and intake o-rings. the last thing I have done is repacked my V&H 4-1 can with #3 steel wool.
I am now starting to look at electrical, mostly igniter box and signal generator. I am going to give my ohm meter a work out. Does anyone have any suggestions? I really need help here.
Thanks
Scott
