Pulled the carbs off Johnny 5 today and did a little tuning on them. Added the Randak suggested washers under the needles (no clips on them - you just put the washer under the head to lift it a bit). Polished slides (again) changed one air jet from a 130 to a 120, and changed all low air jets from 120 (correct for the '78 engine) to 110 (correct for the '77 carbs). Made it so much better! Let's ride!
Oh, and I was having the typical neutral light always on problem (and planning to not try and fix). On a quick ride I tried a little speed shifting (I know, not recommended for GL tranys). The neutral light only comes on in neutral now!
Rode the '78 (Johnny 5) rescue to a car show about 33 miles away. Harley baggers and scooters was all they had 2-wheeled. Ran fair - still stutters some but pulls hard and pulls away from a stop smoothly. Also very mild backfiring, sometimes even burps at idle. After I got home, I got almost a full turn on all exhaust nuts, so that might be part of it.
There was an open invite to ride along with the Harley marketing manager to this show. Since the shop was on my way, I stopped off and then rode along with her (the others that were supposed to go must have partied too hard last night she said). Only about 10% there were masked. I kept my distance most of the time. She got in trouble, though.
