noisey tappets
How big a job is it to adjust the tappets to reduce the clicking and are there any special tools required?

Re: noisey tappets
no tappets in a spider. (DOHC). instead you have wafers between the cam and valves. You need a tool to hold the wafer cup down when you rotate the cam and then a different size wafer to replace the old one. check mirafiori for the community wafer set and tools. Also wafers are available from the usual suppliers and they are only a couple of bucks. Probably worth investing in the tool if you are planning on keeping the 124 for any length of time.

Re: noisey tappets
The shims (wafers) sit in a bucket and to get them out you would need either a dental pick or a little blast of air. Let's say you measured the clearance and you were .004 too small. You'd replace that shim with one .004 thicker. Not a particularly hard job, especially if you had someone like Vetura Ace helping you like I did.

Re: noisey tappets
If you have an assembled motor, you have wafers in there somewhere. i have 2 older catalogs in front of me. IAP only sells in sets. Vicks sells them individually. listed in index as valve shims. you will need a mic or decent caliper to measure your current ones. dont try to make your own. these are hardened and ground. I found a pix to show them. will shrink and post.

Be glad it's not a sportbike. Most of those require taking the camshaft out to change the shims.
