I've bought nearly everything I need for the engine rebuild :
* cNw/Comstock crankcase breather.
* 2 x FAG NJ306E.M1.C3 crankshaft bearings.
* A.N. crank hardware with STD big end shells.
* Webcam # 312 camshaft.
* Emgo(JCC) pistons with Hastings rings (not pictured-at the crank balancer).
* A.N. lifters.
* A.N. rocker spindles.
* Kibblewhite pushrods/valves/valve springs.
* cNw/ARP engine fasteners (head bolts not pictured-back to cNw in exchange for waisted shank upgrade).
* A.N. oil pump.
* A.N. timing chain.
* And the crowning jewel - Fullauto Head.
My original plan was to get the motor rebuilt first.
I'm not sure it's such a good idea to have a freshly rebuilt motor sitting around for what could turn out to be - a long while, so........ I'm going to put the bits back in their boxes and tackle the frame and associated parts first.

Yeah, it was good to tick those items off the list Paul.
Don't think I'll bother doin' a set shot like that again though.
Much easier gettin' 'em outa the bags, than back in :x

Good to be at the bottom of the down hill run.
Time to hit the hill climb :shock:

Ah, yes............colour.
You might need a "cuppa tea 'n a lie down" after this one Fast Eddie.
I think this box belongs to Pandora.
Admittedly, that battery tray looks out of place at the moment. And it's soon to be joined by an oil tank, back in black from the cNw mod shop. But when the side covers and seat are on, only the front lugs that connect to the rear iso mount will be visible. And then they become more of a splash of black, much like a foot peg rubber or a plug lead.
I've spent way too much time thinking about colour and the influence of online imagery. Us backyarders have never had it better when it comes to "borrowing" ideas from the professionals creations, so it's pretty obvious where the silver frame look originates - in my case anyway. I did have a black with black and more black (with shiny hardware highlights) idea for a while. But it was only in my minds eye, and I didn't trust it's point of view.
So, there'll be no more black on this build.....except for the seat...........oh, and the tyres...............and the grips............ :mrgreen:

Oops, didn't mean to 're open the stress' on this one matey! I know what that's like for sure. Trouble is, the more details you stress over and resolve... the more you create!

Anyway, that silver frame looks stunning. If revenge makes you feel better then you'll be glad to know that despite stressing over my frame choice for ages... And deciding on black... You've now got me thinking I shudda gone for silver!

Stripping mine down again would be stupid of course... But then again... I could review the TTI question... and the FA head... not to mention Maney 920 barrels... For which, Maney cases would be nice...

Anyone know a good shrink...?

I must say ELMZY that I have been following along on your build thread and that I too have always thought that a silver or grey frame is the way to go. I will probably be using a POR-15 gray paint (to keep it somewhat flat or less shiny). Yours looks great though!! Thanks for posting & keep 'um coming :mrgreen:

The only negative I can recall from the '75 Commando I had in the late 70's was the seat height. Only getting one foot on the ground was a nuisance - especially with a pillion passenger. I moved on to a Shovelhead Harley and although getting both feet flat was great, I found the ground clearance a handling compromise. In 15 years and a lot of miles across Australia I ground through 2 Primary covers on that bike. Great on the highways not so good on the bends.
In an effort to find some middle ground I've decided to lower this one 1.3" and use a custom Corbin seat.
I bought Atlas Stanchions which are 1 1/4 inches shorter than Commandos, then cut 1.3" off a set of standard springs and cut 1.3" off the top of my original rods and rethreaded them. I put Ikon 7610-1307 shocks on the back. They're 11.8" eye to eye compared to 12.9" for standard shocks. Any other shortarses out there interested - there's a thread on this forum in which Matt from cNw details his experiences lowering Commandos.

Excellent work there ELMZY, you continue to impress. Please keep the updates coming.

About the only thing you didn't explain fully was... the handle bars. What are they exactly?

What's the paintwork plans for the tinware?

Thanks FE.
I bought the bars locally. Genuine A.N. 06-4132, UK or EU Interstate I think.
They were 31 1/2" wide, 2 1/2 rise, 5" pull back.
Too wide for me - especially if I use bar end mirrors.
So, I cut 2" off each end and they're just under 28" total width now.
It's all about triangulation for me. Wide bars tend to open me up too much - and get uncomfortable on a long ride.
Paint work, hmmm - I haven't been drinking this time so hopefully it won't come across as a ramble.
I used to be an Auto Spraypainter back in another life so I'll be brushing the cobwebs off and hitting it with 2 pack basecoat and clear - when the time comes.
I'll be making my own stencils for the logos (on a vinyl cutter). I'll stick them on a silver base, spray with either Gunmetal Grey Met or Graphite, peel the decals off and Topcoat Clear the lot.
No colour on this one - 50 shades of Grey so to speak.

I love the many shades of grey. I used to do a lot of BW photography when I had my mk3 and I still over the play of monochrome light.
