    Only a few ounces of oil will escape during a valve check. No need to empty the oil.

    A K75 will "run fine" even with out of spec valve clearances, but you will experience less than optimum performance, poor fuel economy and increased parts wear.

    I don't mind doing the check, but since I don't have the shims or the tools needed to complete the job if I have to change the shims it seems like inviting one of those "bike down" for a month scenarios. I will see if somebody in the area has tools and shims and do it then.

    EDIT: I could probably improvise the tools

    You really need to do the check to get a baseline and know if everything is OK. If a valve or two needs adjusting, you can put the cover back on and ride it (if it's not crazy bad) until the tools show up and you can schedule the adjustment to your convenience. It's much better KNOWING where things stand, than just hopeing that everything is OK. You want to make informed decisions.

    If you wait until it starts running poorly, you've already started doing some damage.

    You're in fairly good shape, although #2 and #3 exhaust are a little tight.

    I have to find somebody in the area with tools and shims, until then I will ride. If shim says 245, which one do I need to make it right. I guess 240

    .05mm = approx. .002". Shims only come in .05mm increments, so a 2.40 would give you about .011". Any more and it would be too loose.

    If you don't already have the shim tools or don't want to spring for the more expensive ones because you don't anticipate using them much, there used to be a guy that was making them. Don't know if he is still making them. You'd need to call or email him first to check. The quality was good for keeping a couple of bikes in shape for their life time. If you were going to make your living doing valve adjustments, you'd want the better ones. Kind of a Snap-on vs Harbor Freight kinda deal.

    Here's my comunication with him from 6 years ago:
