Ok so you know from other post I have web grind 118 for my 1981 gs1000. I'm setting valve lash and realize the web card says .006". Much more than stock. I called them about it and they said it is because of the base circle. So I go back and start checking clearances again. The book says that the lobe should be perpendicular to the head surface. It seems to me the cam lobe should be pointing directly away from the valve stem to get the right measurement. because when I measure the cam I believe the profile is already starting at the point the book says to measure. And I get more clearance when I point it away not when it's prependicular I called Web about this and the girl was not very helpful. Any help would be greatly appreciated.

Using the Suzuki method puts the cam is a position where two adjacent valves are both on the base circle. Using the perpendicular cam position places one valve on the base circle but the adjacent valve is compressed thus skewing the cam within the journal clearance - thus changing the clearance at the valve (increasing it usually).
I don't think is make a whole lot of difference in the end most of us use the Suzuki method to save time and keep true to the mfg'ers instructions.Ed
To measure is to know.

It is a point that is often overlooked by newcomers to the valve adjustement process, but when you have the cam lobes positioned as the manual suggests (and emphasized by Nessism), you measure BOTH sets of valves on that side of the engine without moving the crank.
Some guys think that the lobe has to point up when checking that valve, but, while one lobe will be up, the other lobe on that side of the cam will be pointing either front or back, depending on whether it's the intake or exhaust cam.
As far as what clearance to use, I would go with the cam's manufacturer's suggestion.

did you install slotted sprockets?
the cams are really a waste and could make the bike runs worse than stock if you do not "degree" your cams.
just thought i'd mention that.Comment

Yes, I slotted the stockers and will see if I need to slot them more once on the bike.Comment
