[QUOTE="Bud-Man, post: 159196, member: 20830"] HiG4s, Most modern 4 stroke motorcycles are using shim under bucket systems where the cam lobes ride directly on the valve. This eliminates a rocker arm and it's recipricating mass. The downside is that the cam has to come out in order to get the "bucket" off and gain access to the shim. As Jeff said, service work will include more than just changing oil. Adjusting the valves is a real pain at first but you will become better at it as you do it. Unless you take off one (or both radiators), there is very little room to work with when checking the exhaust valves on the KTMs. I figured out a way to do it with out draining the coolant and removing the rads, but the first time around I was throwing out all kinds of "colorful adjectives". I've owned both a YZF (with shim adjustments) and now the KTM (with adjustable tappets) and they both have their drawbacks when it comes to service. It's a little more work to do the YZF, but they seem to stay in spec much better than my 400sx. Perhaps I have a problem with my motor, but I'm always adjusting the valves on my RFS. On my YZF, I went a full season and didn't need any adjustments. [/QUOTE]
