Title: Jetting verses Porting
Post by: lauterbacher on March 07, 2013, 08:51:29 PM
For you folks in the know, Is there a correlation between raising your exhaust port timing and having to use larger main jetting? Thanks

No and you shouldn't be raising the exhaust port you should be lowering it.

Raise your exhaust port/increase your exhaust port timing (duration)? ;D
