Just purchased this machine it has 14,000 miles. 2nd owner,,Older fella didn't drive it alot... It runs really rough at low rpms and misses alittle bit on take off.. High rpms runs like a champ. Changed plugs, fuel filter, air filter and also ran sea foam threw the gas tank,, It seems like she's really cold blooded!!! any thoughts. I've only put on 500 miles since I've had it...

Yep, this sounds like classic carb sync. They also do tend to run better and better the more you ride them. Sometimes it takes 2-3 tanks of good gas with Seafoam in them to really clean out and run well, especially if they've sat for a length of time.
With only 14k miles on it I'd think there's gunk in the carbs and maybe the fuel tank. The SeaFoam is a good idea but don't be too surprised if it doesn't work. But it's cheap and easy... those are the first things to try.

At low revs, most of the fuel is coming from the idle circuit in the carbs, these are the smallest jets in the carbs and as such are the first to block with dirt or gunk from old gas.. Your sea foam might clear them out, but unless you are using small throttle openings, most of the sea foam will pass through the main jet and not the idle jets (meaning it won't clean the idle jets!). You need to try and drive it a lot at small throttle openings so the sea foam is drawn through the idle circuits (and can therefore clean them) or remove the carbs and clean the jets out with a solvent and compressed air.
