After replacing cylinder head, bike won't start - F4i
#12
Update:
Okay guys I went ahead and checked the timing of the cams / crank, and here are some pictures. From what I can see it looks very close to being correct. However, I would say that the sprockets are off from each other by 1 maybe 2 teeth. You can also tell from the way the sprocket bolts aren't perfectly symmetric. Even still, does this look like it would cause the bike not to start like I mentioned in my first post?

Also, I noticed when turning the crank, that it takes two full revolutions at the TDC mark, for the cam sprockets to line up with the "in" and "ex" as shown. I'm assuming this is normal?

well if the cams are indeed off from each other by a couple teeth when they shouldnt be and the timings off enough it can but if its off a few degrees than i dont think so. not entirey sure but i doubt it. that could easily cause idle problems though. im not sure what else to suggest right now

compression sound?
Yeah I am thinking it's a timing problem. When I turn the crank for TDC, I hear a compression noise. Would this be the result of improper cam timing? When I get home today I'm going to redo the timing to try to get it perfect.

PROBLEM SOLVED!
Just wanted to let you guys know I redid the timing on the camshafts, and the bike works perfectly! It's incredible that having the timing off by just 1 tooth will cause the bike not to work at all.
I had made about 4 threads on here throughout the process. And I just wanted to thank everyone for helping me out. The community here is extremely knowledgeable a friendly. Thanks again guys!

awesome, looks like i chimed in too late! It looked like your crank was turned 1 tooth too far clockwise, but your cams were alligned properly. When i chnged my cam chain i first put intake cam in 1 tooth off and it BARELY ran so this sounded kinda similar.
Glad to see its fixed, now go ride!
