Advance camshaft 1 tooth?

I’m not going to do this and I don’t want to do this ... but I’m curious about something.

1978 kz1000 cam gears have 30 teeth.
Circle is 360 deg.
360 % 30 = 12.

So that means if I advance my intake cam 1 tooth, it’d be advanced 12 degrees which takes it from 110 lobe center to 98 lobe center.
Stock cams, stock gears, stock pistons.
So intake would be 98, and if exhaust was left alone to stock, that’d be 110..
So lobe center numbers would be 98/110.

Would a bike even run with those lobe center numbers?

Reason I ask is because I know a guy who bought a kz1000 and cams were set like I mentioned above. Intake advanced 1 tooth and exhaust in correct spot.

We were guessing how many degrees 1 tooth is.
Does 12 degrees make sense and is that correct amount of degrees for 1 tooth?

Actually, it would be only six degrees since the cams rotate at half the crank speed. I don't think there would be a problem with stock cams and pistons.

You will probably end up with some idling issue, they are set for optimum performance, in high performance where idling is not important advancement would slightly improve performance.

Cam LC timing is set by crank degrees .
12 at the cam is 24 at the crank so timing 1 cam tooth out would be 24 crank degrees . (86/110)
With the cam a tooth out the bike will run flat.
Your friends bike will have had the intake cam timing set incorrectly by the PO .
It's a common mistake resulting from counting 28 teeth back from the exhaust sprocket timing mark rather than the pin above.
Obviously the timing mistake was discovered because the bike ran like crap.

Try 720 crank degrees for every 360 cam degrees.
720/30=24
110-24=86


.

Ah, makes sense. 720 not 360.
Damn, 24 degrees is a lot for 1 tooth.
Thanks guys for the clarification.

Why not just use adjustable cam sprockets and set the cams exactly where you want them?

interresting;;;; I have a 74 that was hotroded out in the early 80s; 1104, 360 harmon cams ,37 tooth sprocket,16'' harly rim laced to kow hub, lowering 1'' ,streched 3 '' kerker 4into1,flat slides , most important ;;;;27th pin cam chain install [addvancing intake] and the adjustable cam sprocket set all the way retarted ?????? i cant imagin a big dallar build in the 80s would make a comin mistake like that it must have been a old hotrod trick back in the day;;;;;; I plan on degreing the cam s to see what yhe numbers are ,,,

With adjustable cam sprockets as long as the LC's were correct in relation to the crank it didn't matter if the marks were a tooth off ( except when it comes to the next owner not noticing when doing a cam out service )
Not an old hotrod trick but i say they'd got the pin count wrong as usual and were just fortunate there was enough slot to get the correct LC .

That makes sense , this is a slow
restoration for me 1-2 years lol, eventually i will buy a degree kit , and post the degreed settings , The original owner passed away but his sons recall this bike was 1 of the fastest in town late 70s ,
