[QUOTE="Lil' Blue Rude, post: 418994, member: 4627"] Shave .050" off the 40hp head, bend open the reeds stop to around 1/4"-5/16" at the tips install fiber reeds while your in there. Install 50hp carbs and you now have 2 50hp motors. You might check the sticker on the breather to see if there is a difference between timing on the 2 but the head, carbs, and reed stops are the 3 big differences between the 2 motors unless your talking about the 50hp 3 cylinders but those are few and far between. I'd just swap out those parts before I'd mess with swapping whole motors but that's just me. [/QUOTE]
