Hi everyone,
i have a 2006 cbr600f4i.
Recently i discovered an oil leak from the countershaft seal behind the small chain sprocket.
My question is do i need to open the engine in order to put a new one or i can take it out easily with only removing the sprocket.

Thank you for your comments,
Ride safe!

 

No you do not! The service manual will tell you to split the cases to do it. But I was able to carefully slide the old seal out by "stabbing" it with the end of a paper clip or something similar, and pulling it out. Once its out just slide the new one back in. Super easy

 

Thank you very much mate! That advice saved me a lot of work.
I'll try it and will update the post.
