I rebuilt my Gen 1 carbs a few weeks ago.
I found #3 pilot jet was plugged.
I bought the bike from a dealer. The dealer mechanic said he rebuilt the carbs but it was obvious he couldn't remove the #3 pilot jet because it was badly buggered and still plugged.
Too bad he left big pry marks on the throats of the carbs and cracked the air box. The air box had packing tape over the missing and cracked corner.
I have all of those problems taken care of and now the bike runs purr-fectly when it is warmed up. This bike is addictive.
My remaining issue is the carb choke linkage. When I reassembled the carbs, the 2-4 vs 1-3 travel of the enrichers was not in sync. I bent the rod that connects the front and back pairs until I got them as close as I could.
However, when I actuate the enrichers to start the bike, the linkage has a soggy feel. It feels like all four enrichers are not perfectly in sync. It still starts instantly. When I go to half choke 30 seconds later, the difference among them exaggerates. It still runs, but not complexly smoothly. Once it's warm and I turn off the choke, everything is perfect.
I suppose this is just characteristic of the bike? I wouldn't be surprised if someone had designed a sturdy plate to replace the rod between the front and back banks. Even then, it would hard to make each pair move in perfect sync.
This "problem" is not a big deal because bike starts easily and it is only using the enrichers for a couple of minutes....but I have to think others have noticed the same thing...
