That's pretty normal. Especially once the closing keeper half rings work harden and stop compressing. It really helps to have the closing gap very small.I just did my Vert. Cyl. and It was fine, no shims needed. Is it not usually this way? My bike has 17,000mi. on it and I expected they would be a little worn but everything checked out perfect. No closing gaps at all.
Yes, I know how you feel. I bought Ducati Performance 2V and 4V shim kits and the 2V one is picked clean in many areas. I guess it's time for me to go shim kit shopping, too!! The DP one is pretty good in that it comes with 3 each size (4V kit comes with 4 each) but their "sizes" are kinda sketchy... some are dead nuts on and there are others which are visibly different manufacture and they will vary continuously between sizes.I have 3 bikes with 2v motors and will have another soon. I want the shims at my fingertips.
Good question Norm, I know Mike said his shims are consistant all the way through but what about the stock ones? I had to sand the openers on a couple valves (horz. cyl.) and I wonder if they are still as strong?I'm impressed Mike - next time I need some, I'll get a batch from you. Could you tell us a couple of things? Many of us sand a few thousands off a shim to make it fit, how deep is the surface hardness on your shims? And....the big question.... how much are your shims when bought in bulk?
Given what Mike said about his shims, it is rude to mention anything from Ducati in the same sentence. (Doh, sorry Mike!)Good question Norm, I know Mike said his shims are consistant all the way through but what about the stock ones?
