A Norton in a box

Gosh that's a lot of attention just to get the heart of that matter ready for all the rest you must deal with. I"ve often though I can't believe anyone could put such a tedious machine back to snuff as I didn't think I'd ever get done in my cluttered space and life, but one day you look around and can't think of anything else preventing the first tickle and kick off. If you still have bearings out wash em dry and slowly turn and turn and turn, many many cycles feeling for hints of click sticks as take a while for all the imperfections to line up. If so at engine rpm that slight sense becomes a hum of striction using them up for the next guy. My projects come apart and go back together in intense flurries between idleness.

I have +020 750 piston ring kit in stock. Hepolite (as in JCC), if that helps.

Give me a price and lets compare what price I can get, I have to see what my loycal can do for me as well but its up to what the owner wants as he's got to pay for them.

I keep various piston kits on hand, as I do tend to go through a few sets. I have used Hepolite JCC for Norton many times, and JCC pistons in general for at least 25 years, and never had any issues.
I think they are a very good value for money item.

As I just happen to have a set of +020 750 on hand, I thought it might assist you. They would be AUD$200.00 (pistons, rings, clips, pins). Plus post if required, of course.

If you have your own preferred regular supplier, I certainly understand.

Nice catch for the money!

I'd strongly recommend that your friend does research on the oil scavenge circuit on these cases - they're the ones which, due to the forward-located oil return hole, collect a sump-full under sustained acceleration and empty the oil tank, resulting in starved big-ends. Not a problem for the more sedate rider, but scared me enough to do the job.

Well its been sometime now that I started this project, today I just finished the engine rebuild, all new bearings in the motor, the cylinders bored out to 20thu over, this was the longest stop with this rebuild as it took 12 weeks to get the rebore done, was surpose to only be a 2 week wait and so many excuses from the machine shop but the good thing is they have all new moden machiney and did a great job.
The same thing happen with the head work, Mark gave the head to a mate who only works on heads and knows his stuff, took some time to get Noddy to finish the job, but got it back 2 weeks ago, it was a long wait but he done a great job, this motor went back together without any problems.
Mark has been doing a lot of work on the rest of the bike while I had the motor, replacing anything that needed to be replace, so today after I finished the motor I dropped it off at Marks, hes going to install the motor in the frame and when he is ready I will install the primary cases, the gearbox is alread in the frame and connect everything up, ajust the valves, put his new Amals carbs on, set up his new Boyar ignition, so with any luck we should have it fired up within the week, this bike still has the orginal paint on the frame and tank and has polished up very nicely.
Its been a long slow job, the hardest thing was waiting so long for things to get done (head work and rebore) but the wait has been worth it as all work has been done with very high standards, this motor is going to last a very long time, is nice and tight so can't wait till the first kick, Mark is a Triumph man, this will be his first Norton, so hes got a lot to learn and needs to build up his kicking leg, I won't put any pics up till its finished and we have taken it for its first ride in many years.

Another Norton nealy on the road again.

I have the CNW-Combat style breather built by Jim Comstock on my bike. It works great and installs right where the stock one comes off. I did get it in place without removing the engine or transmission. But, you cant take the transmission out without taking the breather off and modifying the engine mount plate on the shifter side. Kenny also highly recommends this breather set up.
I also modified the oil pick up position to the rear which I think is a valid mod. But, if you already put the engine together then yours will be in the front of the motor and will work fine unless you built a really powerful bike.

Well I just finished connecting the engine to the gearbox, the clutch is a one finger operation, Mark can't beleive how soft the clutch is, have turned the motor over to set the valves and made sure the pushrods were sitting on the rocker arms, have very min. oil in the bores (dry bores) so the rings bed in better.

The Norton is looking great, it still has the orginal paint on the frame and tank which came up pretty good, I will take some pics today.

Today I got to go down and sort out the wiring the PO had pulled it all out, it all looks good still and just need the wrapping redone in places and then set up his timing, this is so close to starting so with any luck will be firing up this weekend, but only if everything is finished and not before, but is hard when Mark is so keen to have it running, but I won't take any short cuts to just to fire it up.

Be aware "One finger clutch" normaly means the stack hight is to high...and clutch slip could be likely :?:

The clutch stack is right, I have been doing these clutch plates on Nortons for nearly 40 years and know all about them and what problems that can happen with them, I still have the orginal clatch plates in my Norton after 39 years of hard work it still is a light clutch pull, so I must be doing something right and I don't get any clutch slip, the clutch is also part of my routine maintenance, look after your bike and it will look after you.
I didn't get down there today so will be doing the wiring tomorrow, but shouldn't have any problems, I hope.
