So I might have a slightly different issue with my peacocks than the normal failure (leaking/plugged up). First, a bit of background...
The bike is a 79 Standard, so it has the vacuum peacocks without the octopus of the Specials. Many years ago, I did have a leaking problem on the peacocks, so I installed rebuild kits in both of them at that time. As far as I know, they were working perfectly at that time, I can not remember if I tested the reserve, but I KNOW I had to have hit it any number of times over the last 12 years or so!
At this time, they work about 67%. Basically, the normal vacuum operation works perfectly for both of them. Prime works perfectly for both of them. But only one of them works in the reserve position. Given how small the tanks are, this is kind of a pain...
Any suggestions where to look? Plugged port? Selector put in backwards (is that even possible on these bikes?) Other ideas?
On a only slightly related issue, my new jets from Mikes XS showed up today, so I'll be pulling the carbs again for a jet change. I'll probably clean them out again while I have them pulled just to make SURE all the passages are clean, even though I just went through them in January.
Right now, I know the bike is running a bit lean on top. The bottom was lean until I richened it up with the pilot mixture screws as well. It has a definite "hitch" in the transition between the pilot circuit and the main jets between 5000 and 5500 rpm. Stepping up a main jet size should help me get this dialed in a bit better.
