So, in an attempt to find a niggling fuel leak, I pulled the carbs and replaced the float needles in the VFR yesterday.
Put her all back together last night, changed the oil this morning and headed off to work.
As I pulled out of my neighborhood, I noticed a hesitation. On the highway, that turned to stumbling, but never cutting out or shutdown.
Hrm, this is what I get for not doing a shakedown ride. I had to get to work, and it didn't seem too bad, so I pressed on.
Up to about 4-5k rpm, it was fine, and from there up to 8k was just wishy-washy. In high gears, full throttle would do nothing acceleration-wise. I can be WOT in 6th and the bike does not accelerate at all.
I did find that in 3rd, though, it would accelerate nicely from 8k to redline. I cruised there and back mostly in 3rd and sometimes 4th gear.
My first thought was that the tank wasn't venting right, but I opened it and filled up with gas and there was no woosh or sucking noise.
Aside from the float needles and oil & filter, the only thing I (intentionally) changed is adding a longer hose to the carb overflow vents. It had a short 3" hose that just dumped excess fuel onto the engine. I ran a 2' piece out down the bottom of the bike where I can see it with the bodywork on.
Fuel hoses and tank vent hoses are on correctly. Petcock is to full "On".
Could there somehow be air in the fuel line, pump, or filter?
