I bought my 2000 cbr600f4 with the front plastics replaced with a stunt front end. It came from pa and has a scorpion slip on with stock jets. I was thinking that when he removed the tubes it allowed to much air into the airbox causing it to bog.

Any suggestions/comments would be appreciated

 

"Too much"? I doubt it.

 

I ment to put to much air in the title. I figured the jets are alright since it only happens at high speed and not high rpm ranges
