 First, I replaced the battery with the "back up" one I had freshly charged 4 weeks earlier. That battery came from the parts bike I just bought. I was really surprised to see it "take" a charge.

 Second, I pulled the right sparking plug. Even in the evening outdoor light I could see the white porcelain was blackened. I cleaned most of the tip surround with a wire brush and the electrode gap with some sand paper. I put it back in and the bike ran pretty well after it warmed up.

 The back firing ceased, but I have a "stumbling or break-up (rich)" region around 2500 - 3000 rpm. From there it seemed to "pull" quite well. I rode it all around that night while "bar hopping" without any incident.

 IOW, it brought me home. It was such a wonderful night to ride.

 It was supposed to rain the next day, so I didn't take the bike out. It didn't rain, so I should have.

 Sunday, I did take her out. I added gas from the pump to the tank. A couple of hours later, she did start to miss, backfire and break up a bit. I pulled into a friend's house and removed the right plug. I found it sooty black, indicating a RICH condition. I cleaned it.

 Before putting it back in, I checked the left plug. I found it not as bad, but still sooty black. I decided to swap cyls with these plugs. I rode her all the way home, without a miss.

 Tommorrow, I hope to find time to adjust the carbs and still go for a ride.

 I turned the mixture screw on each carb IN, 1/4 of a turn. I still have some gurbling around 2500 rpm, but it's taking the gas a lot better. 3000 it's beginning to "kick in".

 It's running better but ...

 I took the bike out late Friday "afternoon" but it started misfiring really badly on the right cylinder. I didn't have a plug with me so I had to "baby" it home that way.

 Returning home, I cleaned both plugs with a sand blaster. The former "right" plug won't fire anymore, so it's junk. I carry the former "left" one around with me as a spare.

 I took the bike out later that night (Friday). It was cooler. I noticed a couple of times at small throttle positions the engine would "bog" like the right cyl may not be firing. It would eventually move through this regime and run fine at greater rpm's.

 The bike brought me home with no further incident.

 I took the bike out Saturday evening. I backed the right screw out another quarter turn, since the engine did hesitate the night before after traveling through town and my "cracking" the throttle.

 The bike ran pretty good. It began to sprinkle on the way home. I went through a surprise "safety check" (or field sobriety check point). As I slowed ...

 I asked a patrolman with a flashlight where he wanted me to stop. He said "just go on".

 As I rode by, it appeared they were dismantling for the night. I rode the bike home in the rain, parked it in the garage and took the car out.

 Wednesday evening, I rode the Yammie to a local car cruise. It ran fine until I went to get gas--right cylinder started to miss.

 I took her home and pulled the coil. I was going to switch it with the one from my parts bike. However, it has a different harness connector on its end which will require my "makimg up" & soldering an "interface".

 With the warmer temp fluctuations, I'm watching my plugs for leaness or richness and fiddling with the mixture screws, +- 1/8 turn.

 I'm not +tive, the carbs are my problem (fouling my right plug). So, I've begun to check electrical connections--working my way to the TCI unit. I cleaned and greased battery ground. I only checked two connectors so far, and found corrosion in one below the left air box.

 I haven't returned to the electrical checks. Instead I replaced worn rear brake pads and almost finished cleaning/polishing front wheel.
