Barrels are finally on
And the rear mudguard is also starting to show promise. Once the other holes are marked out and drilled, the brackets will be off for powder coating.
I've sent the cylinder head off for further repair and to see if the valve seats need replacing. I'm hoping not, but sods law dictates that this will be the case. Eh well.. Onwards I suppose.

Most motorcycle problems are caused by the nut that connects the handle bars to the saddle.

The light at the end of the tunnel is just starting to glow dim in the distance. I threw the handlebars, tank and seat on for a little inspiration.
Which helped.. Rear mudguard has now been drilled up and fitted, so the brackets can go away for powder coat now.
Oh, and put the engine lump in the frame.

It's been said before I know, but those powder coated barrels, really do look good.
Even better now they are in the bike, can't wait to see it all done.

They're only 9.5:1 compression ratio. I was contemplating the 'powermax' items at 11:1, but high comp gives off more vibration. Having the crank balanced to suit should make it a nice smooth ride with these mind. Also, 11:1 is also more suited to twin carbs.. I've only got one.

I would have thought that 11:1 would have been a bit high for normal petrol on a bike without "Knock" sensors and advanced engine management, 9.5:1 sounds ideal to me with your set up.

11:1 works fine, but it's a pig to set up right. A friend of mine used to race with 11:1 ratio and got on ok with it. No need for any fancy sensors or computers though.. Just a knowledge of how to set it up right.

Cheers bud. I can't wait either
Update: 28-07-13
Chucked the rear wheel in to make sure the mudguard is bolted up right before the brackets go off for powder coat.
Our survey says 'yes'
Also fitted the seat properly, along with the oil tank and battery tray. Timing side engine plate and oil lines have also gone on. I'm contemplating a new wiring harness. There's nowt wrong with the one that's on it, but I'm wanting to put switches and coils in difference places. Will also be fitting a reg/rec unit to replace the dated Lucas set up.

I really need a bike table. Makes life so much easier.
Is it a keeper will? I hope so with the amount of effort that has gone into it.

Tolerance will be our undoing.

I would hope the same, but if you do decide to sell it let me know!
It would be a pleasure to own a bike built with such care, attention to detail, and engineering skill.
But I hope you keep it a long while!

She's not going anywhere peeps. The next person to own her will be my eldest son when I pop my cloggs. There'll be a couple more for me to do as the plan is to leave them one each.. (did you see what I did there.

Cylinder head has come back from the blasters looking as good as new. New valve guides have been fitted also. Just need to ream them and I'll be able to assemble the head. That'll be the engine pretty much built with just valve timing being the only headache.
Front end is now done. The handle bars were fitted after I took this shot.. I can't reveal too much.. It'll spoil the surprise.
"Hmm, upgrades!" (Neo, Matrix Reloaded)
Singe unit reg/rec and new super dooper multi-spark coil to go with the fancy pants ignition system. The HT leads 'flow' really nicely to the head and the trigger wires from the ignition unit will go under the engine, rather than up the front frame tube.
If all goes to plan, and things fall into place as I'm hoping.. This time next week should see me firing her up for the first time.
