well, got my gnarly in today and put it on. all i can say now is i wish i keeped my FWW. the bike has woken up so much bottom-mid. it is insain!icant keep the front down. it sounds awesome with the answer CF-2 sillencer. the top end has died a bit,but im hopping within the next top-end rebuild to send the cylinder to eric gorr to have him do a mild mid-top end port in hopes to make the power curve nice and progresive. but for now i am happier then a pig in shit with the way it is.
