Silver/Aluminium or maybe polished, just imagine how many tubes of Autosol Solvol that would take  ;)

You'll have noted just how well the space shuttle performed from take off after they stopped painting the main tank though.

first run up on this Sunday 20th Aug just past, racing next weekend, was a little tight for the rebuild of the bike but got there.
Quite an effort. She is a wee bit noisy with the twin megaphones, might need a plan B if we get pinged by the noise police and black flagged.
But great to have Bender running again.

Looks great mate. Good for a few more mph down the straight.
What's the (beautiful) noise limit over there?
I got pinged once at Amaroo Park. 110db  *eek*. Our limit was 98 db. So I took the last turn a bit tighter to get away from the fence and got away with it.
Cheers

Largely wet and cold in Taupo, but hardly surprising. We managed a 6 minute practice at which point we lost the gear lever  *whistle* and for that period kept the running in revs down to 5500 on the newly ground mains.
For the racing we kept it to the low 6's, the new box allowed us to keep the revs between 5 & 6 and bender was humming.
The fairing did suffer some cracking at welds so some remedial work needed.
we also had a progressive smoking problem which I thought was rings, but turned out to be the LH float needle being held open by the tickler spring working its way into the tickler orifice so the carb was flooding the lh side. So most of the pics had the bike smoking  *red* more than I'd have liked.
We had some good racing with an R100, an XS650 with a 750 kit and an 850 Coventry climax (all later 70's machinery). in the first race we got narrowly beaten by a Norton atlas as we were struggling with the tuning the bikes balance due to the fairings, but in race 2 the atlas blew itself to bits on the start line red flagging the race. Flywheel disintegrated. During practice the only other bike in my class (a pre-unit triumph)  had lifted its barrel but luckily not fully hand grenaded. So my a10 was the sole survivor of the pre 63 class over the weekend!
We removed my passengers fairing to allow him to move better and will refit it further forward as he has long legs and isn't prepared to have them surgically shortened  *doh*
But bikes in largely one piece and am knackered from 2 days racing but all good fun.

Nice one Tim! Sounds eventful.
So the BSA won on endurance, and style of course.
Did the dustbin help / change things much?

We certainly had more straightline speed than we've ever had, but then it wasn't enough to give us an edge against the extra cc/hp/torque of all the pre76 bikes which are all 750cc + and mainly have fairings too.
But then the gearbox meant we were not slogging or flogging the engine so much, but it was constantly on song and gearchanging was ongoing. brap, brap brap, rather than whaaaaah! so we didn't need to clock well past 6 and into the 7's like we were before. A 6200/6500 red line should now be achievable to conserve the old motor.
The sidecar fairing did interfere with Mark and was removed, we'll move it forwards as he needs to be able to move. It also took me reflection after race 1 to come up with a plan to manage to get my weight where it was needed which involves waving my gear change foot out in the air and allows me to move forward and left on the left handers, otherwise my feet were locking me to far to the rear and preventing me getting across. So some riding adaption has been necessary.
Mark also wants a new handhold so some changes and refinement to follow.

I'd also tried copper rocker box gaskets but can't say they were very successful and wept all weekend, more than I will put up with...

Once the fairing has been repaired I'll look into rubber mounting it and would also like to convert the front brakes to hydraulic, possibly 4LS

But then also want to progress my road 54 RR and my daughters C12...
see you at Northcote.

Not sure if it will work with fairings but it works with ally mudguards......fitting rubber grommets in enlarged bolt holes may suffice for rubber mounting, Jaycar sells them for cents. Just stops metal to metal contact, maybe reduces stress when bolting up tight as well.

Sounds like a serious lack of commitment on his part  ;)
