Question about Honda Motorcycles
I have a 96 cbr 600 f3 the issue im having is it was running great about a month ago and I stupidly took the carbs off to clean them and do a tune up well I put it back together and it starts and revs great it hits redline and everything so I went to ride it today and it ran fine in first gear and as soon as you hit second no matter what rpm it starts jerking and sputtering like its going to run out of gas if you stop it stalls it starts rite back up and does fine in first again I also put a k and n filter on it some have told me the carbs are out if sync would that cause this any help would be great thanks all
When you strip a set of carbs you should balance them after refitting. The kit isn't expensive and comes with instructions. It could be something as simple as the throttle cables are set up wrong(if one is opening first then the engine may work okay in 1st but bog when under greater load ie 2nd)

SOURCE: carburator problem
Hi and welcome to FixYa,
Offhand would suggest a rebuilt/clean of the carbs. A temporary workaround would be to switch off the fuel petcock, remove the fuel hose, partially drain the carbs and spray into the fuel hose (going into the carbs) injector/carb cleaner. Reinstall fuel hose, turn on fuel. Remove the air filter and start the bike. After warmup, rev while spraying injector/carb cleaner into the opening where the air filter should be. Get a hard paper/board (such as a folder) cut to a size bigger than the air filter but would fit inside the opening of the airbox. Rev/pump the bike slowly building the RPM at about 4~5K suddenly cover the opening (with the board) to fully choke the carbs while maintaining throttle. Before the engine dies, remove the cover. Spray again while revving. Repeat choking/spraying several times. The idea is for the vaccum to draw the clog/blockages.
Pls post back result(s). Good luck and Thank you for using FixYa.

The main jet need cleaning.(you should clean them all though)
Main Jet: Main jet comes into play at three-quarters open to full throttle conditions. CRITICAL to high-speed engine operation. Not only does it meter the gas into the engine, it can aid in cooling the engine as well.

I have had several bikes in my time. and keeping the carbs syncranized is very important. Did you put aftermarket pipes on it? try rejeting the carbs up 2+mm that may help the fuel air ratio?

i have a '98 f3 stuntbike. they are very tempermental with air intake. make sure your air filter is clean and induction to the engine not clogged.
