Bad gasket Replacement = Wont Start

Bike was running around 3000 rpms at idle this fall. Still rode it a lot. But wanted to get it in good running condition.

Engine had a horribly degraded head gasket (you could see air coming out), so I took it apart and replaced all the top end gaskets. Adjusted the valve shims and had a shop change my valve seals while I had it apart.
Also took some rust off the exhaust pipes and clear coated them.
Put it back together and it wouldn't start. Got a good spark on the plugs and the cams all rotated smoothly, so i figured it was the carbs.
Took the carbs off and cleaned them, they are getting oodles of gas now, and there is a new filter in the intake.

Still wont start and I am flat out of ideas.
Anyone have a thought?

Cam timing or valve clearance too tight.

Double check your timing.

As noted above...

Pull a spark plug out and see if it has gas on it. Insert it back into the spark plug cap, lay it across the top of the motor so the metal base of the plug is in contact with the head. Switch the key on and press the starter button, do you have a good strong spark at the plug gap ?

The good thing is, your damn motor can't read. If it says oil on the container, it's pretty much OK to dump in there.... ED.

Spark is good on all the plugs, pulled them and they are all strong blue.

Can timing is good. Double checked when assembling, and is turns over smooth if I do it manually.

And haha Yea, it has gas. I've forgotten that enough times

Checked valve clearance with gauge. All clearances in spec.

Time to check cranking pressure. On all four holes.

Thanks for all the tips

Ignition timing 180 Deg out ? Have you sprayed any "helper" into the air box while cranking to see if you get it to light or pop ?

Nope, I haven't tried any starter fluid. Was hoping that I can get it going without. But Yea I will give that a try.

This is a good point. You could switch the two inner spark plug caps with the outer two.

Be a bit careful here, it's quite hard to steer a bike that's running backwards.

Why is it that people hesitate to reach for the starter fluid? I have seen a couple threads here recently where people where having starting issues and refused to use starting fluid. I use the stuff all the time, it is a lot easier to adjust a carb when the bike runs. Is there something I am missing?
