Progress has been slow. Life is in the way again. I know, sorry excuse.

Finally cleaned out the oil tank, rattle canned and mounted it up. It is all plumbed in now, too, with nice Gates tranny oil line.

Mounted up the repaired centre stand, as well as the new side stand. So, it is both rolling and standing on its own two tires now.

Jim's headsteady and the coils are on as well.

Next up is soaking the chain in my new tub of chain wax, and getting the primary on. I have to clean out the old mainfolds and get the carbs on as well.

No pics today. Too embarrassed about showing a pic of the stands! LOL

Yeah, and there is an strange story in that that I forgot.

My left hand z plate had a crack in it where the bolt holding on the rear battery tray goes through, so I got a used one off of a MK3 from Danno.

After polishing them up and mounting them with the NYCN rearsets, I noticed that on both my right hand z-plate and the left one off another bike, the rear of the three stock footpeg mounting holes were stripped out and very slightly oval. I had to use a bolt completely through instead of the shorter ones that fastened direcetly to the z-plate.

I am assuming this is a common malady for these?

I've encountered ONE stripped thread on a Z-plate, in 20 Nortons that I've owned, built, or restored, so I'm guessing not very common.

Leave ANY bolt or screw loose and you risk the threads being damaged, especially when it involves the riders dynamic weight stressing it!

Haven't been working on my bike for quite a while and am getting back at it.

I have a new engine sprocket key and went to fit the primary chain. I dry fit the key and it looks very shallow. Only about 0.0675 proud.

I can't find my old one to compare and this came from my local dealer. Is this normal or should it stuck out more?

Ok, thanks Paul.

I have seen a bunch of talk about welded rotors flying apart, and my rotor is original but has this crack in it. No idea how long it has been there and I am assuming it is just a surface defect and ok?

I'd use it as is without hesitation.
Agreed, but I always clamp them in between two large washers in a vice, then wind a rubber strap wrench (Craftsman) around the body and see if it rotates at all in either/both directions.

Alternately, you could mount it between centres on arbour on a lathe and run at crankshaft speed to see is it holds up cheaper than a damaged primary chain case …………………..

Don't have a rubber strap wrench let alone a lathe. Will try and figure something else out.

Doesn't have to be a rubber strap wrench, you can wrap the rotor with almost anything to protect it, and use a large set of chan-L-lock pliers (water pump pliers)

I have a smallish oil filter wrench that may work, with some rubber scraps in between it an the rotor. Did think about channel locks as well.

Had the flu for a week them was out of town last week skiing. Was hoping to get the primary together today.

Tried this trick which worked well. Too well. The rotor broke loose with not much torque. Less than 15-20 ft lbs. by my guess and having just some the clutch nut to 40 lbs.

Not finishing the primary this weekend. :(

Better to find out this way though, could just have saved you from a messy failure!

Look on the bright side... whilst you're waiting for a new one, you can tidy your shop up...!

Shop?

Garage with two bikes, my bench, two clothes drying racks, a ride on mower, drill press, and all the shit both me and my wife dump in there cuz we have to.

Would love a shop of my own.
