Any particular reason why? Neither requires expensive tools and isn't too hard to do.
Most likely you will be spending minimum of $100 for about an hours worth of work.
Otherwise, get a cheap timing gun and pull off your points cover. Get the bike warm and hook it up. Darken the garage some, and aim the gun at the timing marks and shoot it. It should strobe on the F mark. Doing this at idle is plenty fine but you can rev to 2500 rpm and shoot it again for your advance if you want.
Unless you had the timing chain OFF, it really can't jump teeth unless horribly loose. Your only timing to worry about is ignition.

As for valves, a wrench to get the caps on/off, a .003 and .004 flat feeler gauge. I go .001 higher on both exhaust and intake to account for heat expansion to prevent valve train binding.
I remove the sparkplugs and points cover. I know the book says to not use the points cam but without the plugs, it turns quite well. From there, follow the manual and it will take you about an hour, maybe less. 1 trick to speed it up is the on 1 setting, 4 valves can be done, on the other setting, the other 4 can be done.
Trickiest part is keeping the gap while tightening the nuts so I get things to barely fit the next .001 up and then tighten and it works pretty good for me.
