Topic: Anyone know tappet clearance for A grind Andrews Cam ?

[754]

 Checking my tappets. Most are at 6 thou  one at 4 thou  one at 5thou.
 Have not been set since install. I am looking for my install sheet right now.

I an  going to leave the 5 thou, set the 4 thou to 6 thou for now,  and check the camchain.

 I have a mild Andrews in a RC 836 and I believe the spec sheet said both the intake and exhaust was .004. If I can find it I will post it,been a long time since I have fiddled with it or saw the paperwork.

That could be it. Don't worry about it now, I got something below that making noise.
 Either a piston or a rod. Looks like I got some work to do.

Are valve clearances determined solely on cam manufacturer guidelines, or are there other considerations? 

[754]

They give recommended clearance,  but I don't have that in front of me.
 Some change from that fearing large clearances. Myself , I trust the cam makers know what works and what doesnt.

.004? They list 500/550/650 but I don't see 750 on the chart? It is listed as "A" however. And ALL the listed cams are .004 intake and exhaust

The CB750 cams are listed under wrong subject 550/650.
The cam names can not be mistaken!
I would like to try a D cam. Numbers not far from RC295. I wonder how the lobes look like

Maybe Andrews have a pile of forgotten CB750 cams in an old store house?
