07 RSVR Factory cranking but not firing... Help please?

Hey all, a little background on me. I'm a Yamaha/Suzuki certified bike mechanic but haven't worked professionally in a few years. I'm also missing a service manual and proper tools where the bike is.

Sooo
I'm working on a buddy's 07 RSV1000R Factory. It's cranking over just fine, has fuel according to my nose, has spark according to the sharp pains in my hand, compression sounds good, but it isn't firing. I'm reading about the brown connector mod and will try it when I am up there next (bike is about 150 miles away). I didn't have my multimeter so I will bring that up and check battery voltage next time I come up, but the battery is less than 2 years old (around here they typically last 4-5 years). There are also no error codes on the dash. Tipover sensor is good.

So does anyone have ideas on what it could be?

TL;DR:

07 RSV1000R Factory
Cranks but doesn't fire
Spark, fuel, compression seem good
No error codes
Tipover sensor is good

Any help would be much appreciated. I did find a 2nd gen RSVR service manual online, but can't download it. If someone can post a link to a service manual that can be downloaded, it'd be very greatly appreciated.

As for me, I ride an 05 Kawi Z750S. From the language on this forum I'm seeing a lot of Europeans, so you all know what it is. Most of the people in the US have no clue because it's not a "Ninja" or a "Harley". Can't find any parts/accessories for it over here either...

Thanks for the quick replies all!

No there are no error codes or alarms on the dash. I've been making sure to keep the battery on a trickle charger so that it won't degrade too much while cranking. I don't believe it's flooding because it's not even trying to kick over. And the bike is located in Fort Collins, CO. I'm in Colorado Springs, CO.

I pulled the tank and all vacuum lines appear to be in good condition and functioning well.

Yeah I tried that a couple of times. Looks like I'll be checking the brown connector, cleaning off the AIT, and going from there.

Thanks though! I do appreciate all of the help here!

So I'm pretty sure I figured out what's wrong... The cam sensor isn't getting the required 12V power. I tried it while key on, no cranking, as well as while cranking. Any ideas as to why it's not getting power?
