Hey there guys, I recently bought myself a 2005 CBF 500, bike is in pretty good condition, ( 37.000 KM / 23.000 Miles ) previous owner said all services were done by her mechanic and last one was done pretty recently, which would have been only 1000km / 600 miles ago.
Before I bought the bike I checked the oil, it was pretty fresh and on level, coolant was spot on as well, overall the bike is in mint condition.

However there's one thing thats been bothering, bike accelerates perfectly fine but every time you hit the 5-6k RPM range the bike stutters a little bit and there's a clear loss of power almost like mild fuel cut and after going above 6.000rpm it just picks up power again like nothing ever happened. I am unsure if this is some sort of carburator maintenance they might have missed? The bike idle is fine and stable, the fuel economy is around 38mpg which is a bit higher than I expected but it might be that im just used to my little old 125cc.
Is anyone else having this issue and any advice on what I should do?
Thanks in advance!  CBF 500 2005 Mid Range ( 5K-6K RPM ) Power Loss. 737901405

if the carburetion is the original one (namely ...)
check ignition advance, air filter and then make sure that carb is ok and with original setting

Hi

Sounds like it could just be a slight blockage in the carb. Have you tried taking the motor to over 6000 rpm a few times just to see if it clears? What about the plugs, when were they replaced? When was the air filter replaced?

Before getting complicated and stripping the carbs down try the simple things.
