Arrrggghhh...in preparation for a long trip this summer I'm pouring over my '06 Wee. I bought the bike with 16k and now have almost 20. Long story short is that after steeling myself for an unpleasant job I find that 6 of my 8 valves are out of spec and one on the low limit. One lone exhaust sits at .010' one at .008 & 2 at .007. The intakes are all out; not much but 2 at .003 and 2 at .0025. I haven't pulled the buckets yet, ran out of time today so I'm not sure of what shims I have. Any suggestions on a shim kit that won't break the bank but has a good selection? Someone has also changed the plugs, pulled out NGK CR8EK will be installing NGK CR8EIX and a K&N air filter. The bike ran great prior to this discovery. Any suggestion would be helpful! Sorry, this post was accidentally posted in the 2012 forum originally.
