hey guys, can someone please help me out? I just put a 05 YZ450 cam (PN 5TA-12180-000) in my 06 Wr450 and it won't start, just cranks over with the electric start and sputters a bit. I followed the book, removed the cover and double checked all my timing marks, all seem ok to me, what could be the problem? I did notice however there is one stand alone timing mark on the flywheel, then a few mm counter clockwise from that there are two more marks with a dash between them, I used the single mark for my timing, and even verified this at stock as when i used this mark the two cam marks were right on the top of the head and the other two cam marks were closer to verticle, just like the pic in the manual states, By looking at the cam i found the tmiing mark looks about one tooth off the wr cam. so what could I have done wrong? please help......... I have attached a pic and it may look like the exhaust cam mark is up a little from the head but that's the angle i took the pic at so the flash woulnd't reflect back, both marks are even with the top of the head when looking straight on to it. Also I count 13 pins between the top two marks, is this right? normal?
