it sounds like top end
seriously now, check the rings... now just maybe (now im just takin the piss), the last fool put oversized rings in when they werent needed... so when it gets uber heated (like after and hour or two of riding) the rings expand and create Uber friction between the bore and rings, effectively making piston travel stupid difficult and resulting in arse running...
hehe, but no... probably not.
The pulling hard bit is relative... if you havent ridden a nsr thats in prime engine condition you wouldnt know how hard it can actually pull... for all you know, your bikes running like a sissy. That being said an nsr running like a sissy will still pull like a mofo but thats not the point!. Pick up a manual, take of the top end and check the wear and tear on the bits and pieces. Piston rings, pistion, bore, gudgeon pin, bearing ect. ect. Also, check your loom. You might have a bare wire that after running for a while shakes around a bit and shorts the system, effectively rooting one piston...
Actually, that last idea is kinda plausible... Check your loom! wrap bare peices in insulation tape... while your at it, grab some wee little cable ties and just tidy everything up, makes electrical faults less of a pain to diagnose in the future...
