I made up a cam sprocket,and crankshaft holding tool with a piece of 3/8" bar stock 2" wide and 18" long.I drilled the bar stock for 3/8" allen bolts 1 1/2" long.Using nuts to hold allen bolts tight on bar stock with the heads of allen bolts sticking out about an inch was able to use two of the slots in camshaft sprocket and torque them to 70lbs.On the other end left threaded portion of bolts out and using the holes in harmonic balance pulley to torque crank bolt down to 120lbs torque.Valves are hydraulic adjusted.Can take a picture of my jerry riged tool tommorow if needed.I also replaced my crank seal and not being able to find a suitable driver used the crank sprocket reversed with the old seal as the spacer and pushed it in with crank bolt and harmonic balancer worked slick will have to remember that one as I have blown two front seals in -20 degree weather on startup..
