In the previous version, it would only suggest a single shim size different, no matter how far off it was. The new version will suggest up to SIX sizes, making it easier to use that really small "checking shim" that you have tucked away for when you get a 'new' bike. Raising the limit to six sizes has only been in the loose direction because, let's face it, if it's too tight, there is no way to tell how far the valve is being held open. Your best bet here is still to see if the bucket and shim will rotate when the cam lobe is not pushing on the valve. If they can rotate, one shim size will likely be enough. If they can't, it will probably be two or more, so just get out your "checking shim".
Sorry, I have not figured out how to automatically transfer information from version 3 to version 4, so you will have to transfer it all yourself.
So far, I have 294 registered users and they live in 13 countries.
If you have already received a copy, you will automatically be getting your new copy in the next few days. If you have not gotten one yet, follow the directions at the bottom of my signature to request one. Please don't send a PM request, even if you include your e-mail address. It only slows down the process. If you have a previous version and don't get this new version in the next few days, I'll try to contact you on the board to see if your e-mail address has changed.
