When you do the "U" shaped tube method off of the drain plug, the level in the tube should match up with the gasket (maybe a slight lower) of the carburetor bowl, correct?
Well, the top of the gasoline in my tube on BOTH carbs went a good 1/16 of an inch into the carb body... I'm guessing that means that the fuel in the carbs is flowing until it completely fills the bowl cavity... too much right?
How, without trial and error... (taking the carbs off time, after time, after time... Can I get the levels to be right just taking the carbs off once?
Is there a certain measurement from the top of the bowl to the bottom of the carb body when the needle valve should be completely closed?
I know I'm grasping at straws and will have to rip everything apart anyway, but I'm just wondering if there's an easier way...
The bike runs well... but it's a little more sluggish that it used to be... even with the vance and hines and upjetting. I DID adjust the height to be even between the two of them when I did the up-jet because one was noticeably lower than the other. I just never realized they were that high...
I was just expecting the V&H to give a little more kick and now that I realize the carbs are basically over-full all the time it's probably running way rich... the top end sucks especially.
There's a noticeable flat spot... almost a pop... at about 7.5k rpm. My guess is that there's toooo much fuel.
Help... apparently I need it. :)
Relax. You're only about a half mm above spec. I would leave the carbs on the bike, drain the bowls, remove the bowls, bend the tang up with a small screwdriver blade (just a little bit!), reinstall the bowls, refill, check fuel level, repeat as necessary.
Smart idea, but I don't think there's any way to get a screwdriver up there to remove the bowl screws. I'll see what I can do.
OH, yeah socket head cap screws FTW!
