1981 GS1000GL Cranks but does not start. Please Help!

Hello! I have a big puzzle for the experts on these forums. I completed a top end rebuild of my bike, and now it will not start for the first time. My dad, who works on cars, can't figure this out either. It ran before the rebuild, although it had its problems, which necessitated this project.

Here's the info:

As posted in the title, the bike cranks, but there is no ignition sounds. No sputtering, anything.

Fuel is in the carbs

The bike has compression (I placed my finger into the spark plug hole and cranked, air pushes against my finger.)

The bike has been timed according to the Clymer Manual

As for spark, it ran before, so I assume that there still is spark.

The pistons and rings were not replaced, but like I wrote above, I get compression

Maybe I'm missing something, hence my asking the forums for help. If you need anymore info just let me know. I appreciate any input that the forums may bring. Thanks!

You do not ASSUME there is spark!!!! You CHECK to see if it has spark!!! Let us know after that! Ray.

I'll post whether or not I have spark tomorrow and we'll move from there

When you timed the cams did you make sure the crank trigger faced left (1&4)
Check the wires going into the pickup coils at the ignition. I knocked one off one time and was lucky I noticed.
Oh yeah Check spark. Even if it's timed improperly it will backfire and make god awful noises.

And if its timed REALLY improperly, those noises will be bad....
