i currently have my buddies 07 cbr 600rr which he crashed and cracked the whole right side of the engine (clutch cover AND crank case) one month after buying it which was really sad. i also have an 05 cbr 600rr engine which i got from another friend. i havent auctually gotten the engine to look at it yet so im not sure as to weather they are compatable. ive seen pictures and they are different colors of corse but i really cant much more than that. if any of you know anything about this it would greatly help me out. thanks alot
