For you synchronization Guru's:
The factory service manual on my VT1100C2 Sabre recommends synchronizing the carbs at a steady 1,000 rpm, +/- 100, until both vacumn readings, (or columns of mercury in my case,) are as even as possible. OK...
(The RPM I guess at since Japan is afraid of sinking into the ocean if they put tachometers on their cruisers.)
My question is that if the main jets between both carbs is deliberately off by 5 numbers, and you set both carb readings exactly the same, wouldn't the rear cylinder carb in reality be actuating before the front carb was? Last time I set my front carb reading to be just a sniff higher, (or greater,) than the rear carb reading was and the bike seemed to run like a champ. Best ever.
The vacumn reading is determined by how much fuel the carbs are delivering down the lower boot and into the port, so why set both carbs exactly the same if one carb must of necessity deliver fuel at a slightly faster rate than the other one does? Anybody here set the carb synchronization off just a little intentionally?
Pleasure is directly proportionate to risk, and motorcycles are inherently pleasurable.
