2011 yfz450r wont start

Picked up a 2011 yfz450r. Had one of the cams 180 degrees out so i fixed that while it was in wrong the quad would turn over. So i flipped cam properly. Replaced stator which was very bad. Then went to start quad and all it did was click. installed new battery, starter, starter relay and starter cut off relay as well. Ran all tests on everything i could and still wont turn over. But like i said when cam was in wrong it turned over but never fired im assuming cause it was so far out of time. i have gone back through this machine multiple times and still with the same result. Wont start. Any options i am missing or suggestions would be greatly appreciated. Thank you in advance.
