Follow the manual and measure everything you can. Are you from Ontario Canada or U.S?

What are you taking apart specifically?

Just take your time, set things out and in order, and take some digital pics when you are not sure. I always like to screw bolts back in a few threads if I can, so that it reduces the chance that you forget which one goes where. Make sure to get a flywheel puller if you plan to swap out the cam chain.

I screwed up one of my chain guides when I did my top end (it was pretty old and crusty, but I also didn't put it in right), but other than that, everything went well and it started quickly.

This was my first piston/rings job (also did the HotCams and cam chain), and there sure are alot of parts on the work bench compared to the two strokes that I gew up with.

Something that is very helpful is one or more of the plastic small parts organizer boxes with 2" or larger compartments. As you remove each set of bolts, place them in a separate partition, starting at the upper left, moving to the right as you would when writing. Put the cam cover bolts in the first one, the cam cap bolts in the next, and so on. When you're ready to assemble, work in the reverse direction from the last compartment you filled.

Even though I can take a box of scrambled bolts and lay them out on a bench according to where they go, I do this quite often anyway, as it speeds up reassembly by reducing the time taken to find the right bolts for what you're putting together.

^^^^^^^^^

That's a prety good method.

I like to take a medium sized cardboard box, use a pencil to poke small holes through it, then put the bolts through the holes. I group stuff together, then use a sharpie to write on the box to label what the bolts are for. This method has worked fairly well for me over the years.
