First off, a quick, run-down on the Hawk motor.

It is a 52deg V-twin motor derived from the early 80's VT500 Ascot V-Twin. 647cc, liquid-cooled, 3 valves per cylinder (2 intake 1 exhaust), chain driven cams, with a two bearing crank.

This is it's weakest point, and there have been many a Hawk racer who has popped a motor, shattering cases, building these things.

New(er) Motor for the Hawk I got a fresher motor for the hawk and have bolted it in and mothballed the old one. Here's a "How to remove a Hawk motor in 61 easy steps" guide. :)

Should I add some hotter cams to a motor with 24,000 miles?
