Hey all, Finally got done last night doing a valve inspection. They all pass, thank god, I was NOT looking forward to pulling the shims out. Anyway, just thought I'd share some tips that I learned. First, a great tool for checking valve clearances is from Sears and you can check it out online at this link: Craftsman 26 Leaf Offset Gauge - Model 40802 at Sears.com For that tool the thinnest feeler gauge is the minimum allowable valve clearance for the intake valves. (.13 mm). What's also cool about this tool is it's bent so that you can easily access the valves. Assuming that you've already taken the cylinder covers off and that you have the service manual one thing to watch for is the intake and exhaust valves are on their own camshafts. When I first started on this I thought the intake valves were on one side and exhaust on the other side but fortunately, that's not the case otherwise I'd be ordering shims. Below illustrates the location of the valves for the #1 and #3 cylinders: Likewise for cylinders #2 and #4 the locations of the intake and exhaust valves are illustrated below: When you rotate the crankshaft to get the TDC for each cylinder make sure to also note the tiny marks on the gears and that they are as noted in the service manual as illustrated below: If you don't know what I'm talking about with the tiny lines see the below screencap from the service manual: Oh, and when you have to put the cylinder cover back on put a tiny film of the silicone sealant around the gasket so it won't move as you put it back on. And that's all for the tips! Thank god we only have to do this every 16,000 miles. The Kawasaki Concourse needed this kind of work every 6,000 miles!! EDIT: Since a member here asked thought I'd post for everyone's benefit that for the gasket sealant I used a product callled "Hondabond HT Hi-temp silicone liquid gasket sealant". You can get that at the local honda motorcycle dealership or you can google for it online. If you don't have a service manual you can download one from this link: http://vfrworld.com/forums/parts-service-manuals/3161-downloadable-parts-catalogs-service-manuals.html You can just print out the pages you need and have them for handy reference when you're in the garage. EDIT: May 20, 2009. It's valve adjustment time, I'm at the 32K mile servicing and found some valve clearances are too tight. So for the benefit of everyone thought I'd share some more things I learned. First, you don't need a micrometer to measure the thickness of the shim. Thoughtful honda prints out the shim thickness on the shim themselves. They look something like this: Note that even though the number printed is 3 digits it's really X.XX mm. So for example if you see a shim with "175" printed on it that's really 1.75 mm thickness. Now, you're probably thinking you'd have to buy new shims, right? As it turns out you can just go to the honda motorcycle dealership and you can exchange your shims for whatever size you want. That's a real money saver there, especially if you screw up! Once you've got the new shims installed, an easy way to confirm the clearances is to only install 4 bolts on the camshaft holder as illustrated below: Make sure the 4 bolts are snug enough so that you can't really tighten them enough without considerable force. This is important to ensure an accurate valve clearance inspection. If you leave one bolt loose then your inspection won't be guaranteed accurate because the camshaft isn't held down properly, resulting in a false reading of too loose clearances.
