routine maintenance question
 

Troy,

I'm a new YS owner. I bought a used .63 from an online buddy and am very impressed with it...very reliable and powerful. I should also note this is my first 4-stroke engine of any brand. I know 4-strokes need a valve adjustment from time to time so last night I pulled the valve cover to take a peek at the top end. After turning the engine over and watching the rocker arms, pushrods and valves do their thing, I quickly realized I had no idea how to proceed. :) I'm pretty handy and have had good success taking care of my 2-stroke engines and am confident I could do the same with the YS, but I'm just looking for some how-to information. I know you're busy and don't have the time to hold my hand, but can you (or perhaps other readers) recommend a source for thorough and accurate instructions on how to perform simple maintenance like valve adjustments?

Thanks in advance,

Erik
