While rummaging through my computer files I found a Shim calculator for all four Japanese motorcycle brands that I acquired in late 2009. I don't remember it at all. Can't say where it came from nor can I find any evidence of its existence anywhere on the Internet. It utilizes two languages, fortunately one of them is English while the other is as indistinguishable as Greek or Russian with an alphabet I do not know. It shows the Union Jack to select the English version and a flag for its native language that I cannot find while perusing all of the flags of the various nations.
I have yet to use it, but after inserting various measurements and using it to calculate the shim requirements for those measurements I think the program has merit and will be useful. The next time I do a valve adjustment (very soon) I will give it a try and then be able to offer valuable feedback.
The three pictures below show it in use with just a couple of #1 cylinder calculations to give an approximation of its capabilities. As stated above, I have no idea where I got it or where one can find it. If anyone would like to have it for experimentation or use, send a request via email to pseudonym@sysmatrix.net and I'll send it to you as an attachment. Specify either .rar (284 KB) or .zip (366 KB) as I have both.
The pictures show Honda but there is an option for the other three Japanese brands as well as the shim sizes.
I JUST LEARNED FROM JIM PAVLIS THAT THE PROGRAM CAN BE OBTAINED FROM: http://vicdzen.narod.ru/main_eng/
