Thanks abe!

The valve shims are the same on all newer Hondas. I used shims I had from my CBR. The Ruckus is very easy. The shim sits on top of the valve but has no bucket over top like big bikes and cars. Shims are the best and really easy to learn. It just takes time and you need to write down all your clearances and shims #s on a chart or grid paper. With the Ruckus it's only two valves and you don't need to remove the camshaft. If you want you could go to the dealer and trial and error shims in the parking lot until the clearance is correct. Below is the real way.
Please read this part!!!!! I'm not real good at explaining stuff as you may know. So.. experienced people please PM me to help talior my explaination. I will delete any other posting giving other ways to check valves. I want simple layman input also. If this doesn't make sense to you new mechanics please just post replies and I'll answer and taylor the explaination. This is why I don't have this on battlescooter, I need help to make it as clear and exact as possible. A valve adjust is very simple and even more so on the Ruckus. Any one who can build with legos can do it. I'm sure I left something out. So please help me out and then together we can help others
Valve check----------------------below
1-the engine must be dead cold, do the adjust after a good night of rest.
2-I guess the valve adjust needs pictures. I'll get some on
battlescooter ASAP.
3-valve clearance
intake-.004in or .10mm
exhaust-.007in or .19mm
Find top dead center-remove the spark plug and slowly rotate the engine buy hand until air pushes out, use a pencil to feel when the piston is at the top.
Remove the valve cover-check to make sure the cam lobes are at the lowest point, not pushing on the valves.
Measure clearance-use a feeler gauge to check the clearance. Find out the max gauge that will fit and the one that just barely drags.
Compare-subtract to find the gauge that is between the two you came up with. Compare that number with the recommended clearance(aways use the number in the middle, the book gives you a min and max).
Remove the shim-the Ruckus is a snap. You can slide the rocker arm to the side or push down with a finger on the valve while holding a magnetic pen near or on the shim. It will pop out on the magnet. Read the number and write that number and the valve it came from. Do the same on the other valve.
Select a shim-the shims are marked like 218 or 198, that's .218 or .198. So then add or subtract from that shim number to make your clearance correct.
Pop in the new shim, check the clearance. If it's correct your done! If it's not correct go to the next shim size and check again. If it's perfect button it up and ride like the wind
