Hi all, I have a Honda CBR 600 1998 (F3) which is suffering with mid range power loss, bogging etc.
Riding the bike at speeds over 30 and as soon as you hit 5500 RPM it just boggs down and looses power until about 6500, 7k when were back on the power.
I have replaced, plugs, air and fuel filter and even had my local bike shop strip, clean and Ballard the carbs. Battery seems fine as it churns over for ages if required.
Exhaust has a slight blow top of manifold but bike shop told me that is not bad enough to cause this issue.
Any ideas on what I can try next please.
