I had one valve out of spec which required a shim replacement. We all know that the the recommended services can be expensive and that chances are that your valves clearances will all be within spec. Consider that this is your first internal look though Leigh.
I am of the opinion that when I have this much money "invested" in my Rocket, I am not going to put it at risk for $180.
At some point though I think one should be able to do all the services, to include valve adjust. I used to do it on my Kawis which were shim under bucket. I'd check the valve clearance, look at the chart to see what I needed and head out to the local dealer to buy the shims at about $2-$3 each. I generally needed one or two every 12k miles.
Well, just my thoughts.
