[QUOTE="radman, post: 367889, member: 167"] The cooling system is apart for the job, if over 24 thousand miles (a figure I just pulled outta my ass) a new thermostat would be a good idea. A thorough cleaning of the throttle body plates would be easy now, as well as a careful inspection of the intake manifolds, any deterioration would be easy to spot, though unlikely, but still..... Cleaning and inspection of the reed valves for the AIR would also be easy now, if they are still in place. Inspection/replacement of the water manifold (head to thermostat housing) is called for-the wells the tubes run into at the valve cover retain rain/water/dirt, and the manifold corrodes rather quickly as a result. I wouldn't replace the intake valves, but new seals, as well as a valve lapping, would insure perfect sealing, and restore horsies usually slowly lost over time, in fact, you may find the bike has never felt stronger. Many hi perf motors I've built have benefited from a valve freshening soon after a new build, if only because once everything has seated, small variances creep in. [/QUOTE]
