I was just wondering if anyone anything about that fx8 kit from blackmagic ? I got an f5 only got 299.6 miles on her and was wondering about the kit if it will work with my block? yeah your probably thinking not even 300 miles. Well I got it at the end of feb. Had a yamaha exciter (freebie) put about $2000 into it, driving back to our cabin one night racing my bro-in-law (he was on a prowler) saw a straight away cracked the throttle hit about 70 ,then there was a tree in front of me hit the brake went sideways. The next thing i know im about 40ft off the trail my sleds on top of me didnt get hurt though felt like an ass . but i didn't feel so bad because my bro did the same thing. we both got new sleds now.
