[TR] re-using timing chain gear

["sujit roy" <triumphstag@gmail.com>]

My Stag has done about 7k miles when one of the timing chains crank shaft
sprocket had complete worn down causing major engine failure. (valves
impacting pistons.)  The cam shaft and jackshaft sprockets look OK.

I'm planning to change the chains, but I would like to reuse the good
sprockets.    Is this advisable or should I change the whole lot?  As
mentioned the gears have only done about 7k miles.
