How many times can you shim the valves before you need to get new valves? My friend is a mechanic but mostly car stuff. He claims you can only shim them once then you can do it again but you are going to have the vavles break. I guess I am really nervous about my bike having valve problems at some point and I dont want to let the bike motor just grenade on me and then I have to pick out shapnel out of the case. I am going to check clearances here soon just wondered what I have to do if i need to shim again.
