124in. Engine Build (page 1)

Picture 55 shows checking the rocker arm end play, evidently .006 on this one. This is a pretty loose spec., just needs some clearance and too loose it'll be a "ticker".

The pushrods are in their respective places, lower boxes being installed along with the rocker arm support blocks. Torque sequence and specs should be problems there. (twin cam boxes basically) This is done with the camshaft lobes aT their lowest point... I do one cylinder at a time, then spin the motor for the other cylinder.

Ignition rotor blue loctited on, and crane HI-4E installed.

All box bolts and support blocks torqued, Surfaced cleaned and gaskets installed for the tops installation.

Torqueing the rocker box tops down...again simply follow loctite. Each bolt gets a small rubber coated washer below the bolts steel washer. Go around the rocker box in sequences up to the desired torque. Criss cross pattern, dont tighten one corner all at one time.

Time to adjust the pushrods. Find TDC for that cyl at a time. These lifter came with a limited travel kit, so adjustment is a bit different than most evo lifters. With a cylinders cam lobes at their lowest (TDC...piston at its highest...comp stroke) the rods are lengthened 4/5 turns from zero lash. Walk away for 15 minutes and see if the lifter bleed down, allowing the pushrods to spin within your fingers. If they do, lengthen them another turn or so, walk away again... Do this until they DON'T bleed down. This means you have the lifter collapsed fully, and you have pushed/raised the valve off its seat...and the valve is held open. So you wont be able to spin the pushrod. This has to be done cold, if you try to adjust on the bike you are riding. Anyway...once fully collapsed, and not bleeding down...slowly SHORTEN/COLLAPSE the pushrod. All of a sudden it is gonna JERK free (meaning the valve hit the seat, and stopped moving, thereby the rod gets loose all of a sudden). Take note of this, and go 4 to 6 more flats SHORTER. pick a them all the same. Use your 3 wrenches and tighten the jam nut snug right there. This is kind of a dexterity challenge and if you slip or lose count of the flats, you will have to start over on that rod...lengthening it till it raises the valve off its seat. If you lose your place...forget it...start over. A flat is ONE SIDE OF A BOLT...hence 6 flats on a bolt or nut. Install the pushrod tube top spring clips...done. Rotate the motor forward after you have done one the TDC of the other cylinder. do the same entire procedure again.

WOW! I'm about to contribute to CC again. The value of info like this... If everyone on here could pony up just $10.00 or so once a year... You'd all be getting a great value AND BigB would be able to afford all the redundant goodies so we would never go down...
