Does cyclepedia.com offer a manual on this scooter?
Have never seen a video diy on your scoots valves.

  valve jobs are much the same on 1 cyl engines get the valves spec.s 300i     0.10 mm.  other info is how to get to the valves   so look up any bike and see how they do it

I agree with De Dee.  They are all basically the same. 

TIPS:
Get METRIC ONLY feeler gauges - when you use two sets of gauges or SAE (by selecting the metric equivalent) it is easy to pick the wrong blade.
Get angled feeler gauges and straight as both types are useful.  Make sure the kit you buy includes the sizes you need.  They are usually listed on the package.

Use the one up one down method.  If you think you adjusted it right try the next smaller blade - it should be loose.  Then try the next larger size up the gap should be too tight for it to fit.

Finally, I last adjusted valves like 20 years ago on my 1985 Mazda 626.  So in 2012 when I adjusted my Kymco GV250 at 10K miles I was rusty.  First time I adjusted too loose and heard a lot of ticking.  Next day I went back in and got it right - nice and quite.  I'm approaching 16K miles and will recheck the valves at 19K.  Moral of the story .... take your time and be ready to redo it if needed.
