Not much difference in Long verses Short rod engines, displacement is power and normally a larger CC cylinder will make more HP/TrQ...34-40MM carb?...Go with a 38MM-39MM, sounds like you want a little speed yet still ride on the lower gears as well with good throttle responce.

Search and read around on here first, already some pretty good info.

For nearly 10 years, I ran trails on my 86 with a 265cc 88 cylinder with a mild cleanup of the ports on a short-rod bottom end. With the 89 clutch update, a CR head gasket, 38mm A/S carb and an FMF exhaust, it did everything I needed it to do (on pump gas). I probably put at least 25k miles on it when I was in college, then I upgraded to a long rod crank and bigger bores. When I decided to build another trail machine, I went to my parts bin and dug out that same old cylinder, carb, reeds and exhaust. It's still loads of fun to ride a small bore in the trails.

Can't beat Honda OEM engines, cylinders and components for reliability & longevity...still the best after +24 years.
