I have searched for awhile in here on this carb. Ireally didn't see specifics other than it will improve mid-top. By how much? Will bottom end suffer at all? I see the 4-2 needle seems the best at 2.05 length. Is that in inches from tip to bottom of the slide? I found lectron.com and they will customize one for my bike at my elevation, etc.
Anything else I need to know about setup, or fitment? Thanks
