Hi folks, I am from India and own a Cbr600f3 bike was great and running amazing. Recently i had a issue with starting on self my mechanic told it’s because intake exhaust valves are worn out has to be replaced. Did so ever since my bike is not running on load beyond 3k rpm. With out load it revs upto redline.
After which i replaced all the jets thinking earlier size was small even after this it’s not running beyond 3krpm 3rd gear on wards.
1st and 2nd gear goes past 9k rpm.
Please help what could be the issues and how do get my bike run better in all gears.
