Hey guys i am new to the site i have an 01 CBR 600 F4i. And the question is if an engine from an 04-05 Cbr 600 F4i Will Bolt up to my bike?? Thanks Alot

 

Yes it will. Only noticable difference from my understanding between years are the seats but im pretty sure the engines are the same between all years of the f4i

 

Thanks man i appreciate it

 

Just keep in mind that the '01 F4i used different spark plugs than the '02-06 F4i's. The engine will bolt right in and work fine, but just remember whenever you go to buy spark plugs, you need to get them for the year that the engine is, not your bike because they will be different (what the difference is, I have no idea.... but service manual states '01 takes one plug, and '02+ take another)
