I'm about to pull the trigger on a extended swingarm for my 04 CRF50. I'm a taller dude, 6'2". My question is, should I go with the +2" or the +4"? I will also be adding a taller fork setup as well. Any suggestions/opinions on which of the 2 length swingarms I should buy? Not really interested in brand suggestions, as much as I am in the length. Thanks!!!
