Hey guys, I picked up a pair of AAen twin pipes for a 800. Would there be any gains in these pipes over the big single I'm running now. If I was to use them I figure some jetting changes are in order, does anybody have a base line for these pipes? Can't contact AAen until Monday to find out the particulars. I know I will lose a little on the bottom and I can afford that as long as the top end gain is worth it. What do you think? Ron.
