My low hours, well maintained 300 xcw pulls very hard from bottom to high mid range - but then seems to suddenly drop off power at the top.....until  the next gear is hooked....... then this repertoire is repeated  ???
I fitted a new plug, cap and wire, cleaned carb, cleaned pipe , fresh petrol, new airfilter.....but still the same.
I am thinking that it may very well be non - mechanical . Whats the view of those in the know please.
