So I finished rebuilding the carbs and got the bike to fire. The jets were clogged. A little tip I picked up from an old school guy at a bike junkyard which worked great for cleaning jets and small areas is to use a steel guitar string (the smallest E you can get) to clean out the jets. This worked GREAT for me.
My problem is that the bike starts and runs with no choke at about 1000 rpm and then after a few seconds of running it will jump to 4000 and some times fluctuate between 3000 and 4000 or just stay there around 4000 rpm. Can my AF screws change idle RPM ?
I'm also having issues with the choke sticking but I know thats due to residual varnish/gum that is being dislodged by the gas I'm running through the system. If I remove the carbs and clean it out after they stuck there is always varnish in there. Is there any lubricant that I should put in the choke piston area ?
I'm have no vacuum leaks and I've plugged any hoses I'm not using. I'm running off a fuel bottle I made, not the tank. I've got the air box disconnected for quick removal of the carbs for cleaning or AF adjusting.
After I got the bike running initially, I killed it and bolted the air box together and connected the other hoses. Bike wouldn't start. Figured it was fuel. Pulled the carbs again and took them apart from the top and bottom. There was varnish/gum all over the parts which were freshly cleaned even after these carbs sat in a parts cleaner bath for days. Cleaned them by hand again and unclogged the jets which had gotten reclogged. I've done this twice, the second time nothing was clogged but there was varnish on 3 of the 4 needles. The second time the inside of the carbs was fairly clean.
Then I put the carbs back on the bike and it fired right up. After it idled ok. I had thought I had the set the AF wrong for carbs 2 and 3 so I pulled the carbs off and changed them. I have a jet kit (installed before I got the bike) and the AF screws were set out to about 2.5 turns when I got it. Thinking back on it I can't remember if I set all the carbs to 2 turns on the AF screens when I adjusted carbs 2 and 3 or if I pulled them off again and did it later.
I am thinking I should set the AF screws back to 2.5. I'm going to do that this coming weekend and see what happens.
