Vic- No it was the wrong piston. Got the replacement one, same box, same part number but this time looks just like the one I am replacing. At first I thought the same as you "oh, they changed the design to something better". Nope, not going to work with that wrist pin location change! Oh yeah, correct new piston went in 2 Sundays ago, engine's got 5 heat cycles on it now! Almost ready for riding season!
