yes, finding top-dead center is everything on a 4-stroke, my XR650R is a kickstart-only bike with no auto-decompression, just get it slightly past TDC, let the kick up and give it a firm kick all the way down and it fires right up everytime with no hassle, this works on all 4-strokes with proper jetting.
someone really should make a video on proper start-up procedure, I see people everywhere complain about broken kick-start gears, kick-back and hard starting so a lot of people are doing something wrong.
