Trig, with regards to second rotor/caliper, do you know this article? Maybe you can find some inspiration there?

Yes, I have read the link but, they are taking about the bike they are working on, there are many different types of fork legs   ;)

Re torqued the head down and now time for the cam and rocker cover to go on.
Set the timing mark to 1.4, a smear of graphogen on the cam journals, cam shaft in from the left side with the cog on and line up the notch with the top surface of the head and the notch facing the front. Lift the chain on to the cog and locate the cog on the shaft. Have the sprocket bolts nice and clean, a dab of stud lock on the threads and torque to 12ftlb.

Rotate the crank 360 degrees and make sure the timing marks all line up. Turn the crank a little past the 1.4 mark to were the spring is mounted. This is the best position to set the cam chain. Tighten up the top bolt on the tensioner and loosen the nut on the at the bottom and it will automatically tension itself, hold the screw in place with a screwdriver and lock it using the nut.

Coat the cam lobes with a dab of bearing guard. Some people will tell you that you just put the pucks/ head sealing rubbers but, I always smear Honda bond on underside of the lip.

Prepare the rocker cover and take back the tappets and hold them up with elastic bands and a new gasket lightly smeared with silicone grease and bolt it down starting with the 4 bolts under the breather cover and work out a couple of turns at a time. Once bolted down put the breather cover on with a new gasket and a smear of silicone.

In my early years I always had trouble setting tappets, my teacher explained that you need 3 feeler gauges. If you are setting the inlets to 0.05 and it is just dragging, try to put 0.08 in, if 0.08 goes in then it is too loose. The same with the exhaust clearance, if you are setting to 0.08 and you can get 0.10 in it is too loose.
