80 CB750 stock (sans V&H 4-1 exhaust i installed 5-6 years ago)
99% of my riding is on the freeway to and from work. This week we have had vast fluctuations in weather/humidity (45 in the morn to 90 in the afternoon)
and the other day on my way to work in 5th gear @ 6.5k RPM (no idea mph, speedo pegs @ 85 assuming 90ish) i noticed as i approached 7k the bike would bog and not accelerate any further, it was like it wanted to but hit a 'governor' of sorts. this has not happened before, I've had it beyond that many times.
the carbs were cleaned and rebuilt 4 seasons ago, i did notice a few weeks back some leaking gas from the overflow, figured a stuck float so i knuckle punched the carbs a few times and got it unstuck (i assume, no more bleeding fuel), using carb cleaner in the interim until i can tear em apart again.
the bike has been idling high lately when warmed up (1.8k) i can 'unload' it back to 1.5k by put it in gear and letting out some clutch then pulling clutch in again. I rode home from work (25miles) and adjusted the idle screw under the carbs when i got home to bring it back to 1.2k. (fyi i have always had to choke it for a minute on initial start up and adjust the choke for a minute while it warmed up a bit)
i haven't had a chance to ride it since then due to heavy rain and 45 degree weather this week.
there was a very strong 35mph cross wind with temps in the upper 80s that morning it was bogging out. <-- the wind causing vacuum issues perhaps?
