I did a complete engine rebuild this week on my 99 indy 500 classic touring, after blowing up the crank and case. new pistons, rings, seals, gaskets, etc. the rebuilt bottom end I bought was from a 96 500 lc fuji. Dealer looked it up for me and says 96 - 2000 is the same motor. After putting it all together and putting it in the sled, started easy, good compression, (125 both jugs), but there is a "knocking sound" that seems to be coming from the mag side. Could it be timing maybe? lined up the stator the best we could to the marks. I don't want to rip this engine apart again unnessesarily. Any help is appreciated.
