I just replaced one of the cam chain guides on my 09 r1, retimed the cams and now it wont start. It cranks but won’t turn over. I tried starting it with my other battery from my r6 to make sure it’s not the battery but it does the same thing. Any suggestions as to what it could be?

Your cam timing could be off. Does it crank fast, slow, or the same as before?

Maybe when you put everything back together you forgot to plug something in... coils, injectors?
I would double check cam timing, and maybe along the way you'll find you just forgot to plug something back in.
