Can’t get the proper gap for valve adjustment

[STL SLICK]

While doing a valve adjustment on my '91 600, a ran into a problem with the # 2 exhaust valve. I can't get the proper gap. The tappet screw and valve maintains constant contact no matter which I adjust it. The valve springs just contracts or expands. Does anyone have a clue as to what might be wrong? Thanks!

are you sure you are on the correct timing for that cylinder and that set of valves?
if not you may need to rotate the crank 180

Cylinder's not at TDC on compression stroke.

Yeah... your goofing something up.
When the engine is cold and the cam rotated correctly the valve is seated (can't move) and the tappet is free (because the engine is cold).

No, I'm not sure. How do I find out, and how do I adjust the crank?

Ahhhh see there?

You really need a manual.
Read this:

Trinc's procedure is for a 98+ 750 but the plot is the same.

Nice shooting Smokey!

I just adjusted mine over the weekend, a manual will help. If you have questions, PM me and I can help you out.

Don't know how I "goofed" anything up - not saying that I didn't. I adjusted the other valves just fine. I'm still new at this, so please bare with me. If I missed something, its simply because I did not know.

I'll be doing mine this weekend too.

Don't take offense, I just meant that you didn't have something right.
Obviously if you are asking about how to rotate the crank I doubt that you know what you're doing. That isn't a bad thing.. That is why people are here.
But adjusting the valves without having the cams in the right position:
1. will prevent you from being able to really adjust them (the symptom you described)
2. cause a whole lot of damage.. (think all new valves, pistons etc.)

New to bikes? Not a problem here, Someone has never even changed the oil before?
That puts them along with 5436 other members here. I think the links that Smokey and I posted should get you 99% there. If you have more questions post them up, PM me directly or jdm5770 offered the same. I won't bash someone for not knowing how to do a job, only for not admitting they don't know how to do a job! Heck I have given out my phone number as have many members here to help out other members..

Lets get you fixed up!

PS.
The big thing to remember about adjusting valves is that you only adjust some with the crank at one position.. The rest are adjusted at a different position..

That's the key, and I found at first it to be a little confusing but if you look at the chart when the cams are in the "C" position, you only adjust the valves in the picture that are labeled with a "C" then spin the crank (leave the bike in gear and turn the back tire) to the "D" position and adjust the valves labeled "D" (I am referring the the above links given) As with BP, PM me and will give you my cell number and I can walk you through it; I know it can be frustrating at time
