They seldom are an easy fix. Goodparts for a secondhand or there are cheap aftermarket generic ones.

Russel bleach?

Mr 111   Slight had it outside NZ but Russ asked for and got it locally.

Still got a couple of race bikes. And an air compressor. Undercut a GSX1150 gearbox a couple of weeks ago so still doing a bit.

I know of a couple of others whose race number was either street or work adress. Then there's Russell who could only cut straight pieces of tape.....

Once upon a time we were told at club evenings not to ride around with numbers on the bike as it could potentially invalidate an insurance claim.    Never heard of it happening.

Also haven't heard of a club evening since i think 1975.

I suspect Sam's quick turnaround is due to his being "in the trade"

How do people keep track of

That fork is rim this bike 50nyears ago, the engine was sold to Bob tinker who used it as a pump engine for 34 years, after the big flood of 86 John crimper dug it out of the mud and set a flying mile record on it the same day. This leather was from the boot of rex donegal after he crashed in 1921, stray dogs chewed on it for 62 years

You'd be surprised how close your satire is to truth.  The Excelsior and the early Manx were so expensive and rare that the bits taken off at some point can be tracked quite easily.  My first race bike was an ex Len Perry ex IOM Manx - with a BSA engine from a well known speedway sidecar - and is now again a Manx as someone had the engine and reunited engine and chassis.  The Manx engine had been in a Cooper car for some years.

Edit - And i'll bet real money that someone knows where the Manx engine is from the now Norton-JAP. And has approached Inia at least once to try and buy the chassis.  I've dealt with the Auckland based crowd before. Fuck the bikes history as a special, it's worth more on the international market as an early Manx. A chance to make money and fuck NZ racing history.

The lack of a front brake is interesting. Suggests that the bike was multi use. Did he ride it on Waiheke Island prewar ?

I'd be curious to see how much water comes out of it.

Not uncommon when you've got a chamber working well to have to retard ignition at some point in the range. Couple of degrees at a time, testing as you go.

You've opened Pandora's box here. Once you get into 2 stroke tuning you can go down some serious wormholes.

Find A Graham Bell's 2 stroke tuning on line - there are free sites with it. Download it and read it. It's basic by current standards but it'll do you.

Rebore as small as possible. Leaves some life in the barrel - and you aren't moving port edges very much.

Ken made the rules so his bikes with desmo and electronic ignition and belt drive pimary can run in the factory class

Yeah. Last time I was up there with a group when we gave our names to anyone it was Joe Smith MacIntosh. Added it to all our names. When asked why the answer was "Cos if you're a MacIntosh you can do anything"   Which usually shut the enquirer up. After which they usually agreed with us.

I've had a couple of face to face goes with Ken over the years and he will concede the CAMS way has a lot going for it.

Basically that it's not Auckland based.

Oh sorry, Don Cameron is the guy in the old photo, I think he got it new, he gave it to Inia some time in the 1980s, Ken Mcintosh banned this bike from the registered for a wile.

The register had some strange attitudes. Still has in some areas. I've told Ken what I thought of some of their decisions.

Thats Inias, the one I am riding at the moment

I could have guessed that. Who is it in the period picture ? Who built it and raced it in period ?  I was under the impression Inia only came on the scene when the register got going.

So whose was the Norton JAP ?

While you're faffing around in the passenger side, lube the bloody cables to the bonnet and boot releases. they were so stiff on ours it was a right pain. And i believe the next owner actually broke one of the levers. Like the door catch, shit die cast pot metal.

Designer's brother in law owned a plastics factory sub-contracting to Honda.  At a guess.

There's a few sheet metal places in ChCh who would roll them up for you. Might even be worth asking the metal spinners too.

Will swap for a zzr1100

You don't want a ZZR1100. Believe me, Go for the next model - the 900. Much better.

Yes the 500 JAP has a GP carb with twin float bowls, it sucked them dry, I went up 2 teeth on the engine sproket, i needed more time to try one tooth less?

One guy did 370 kms on a GSXR1300 yesterday, they sed its almost impossible to see the markers at that speed, and had bits of birds splatted on them. The tire Barry's were onto me to

I bet they were. Looking at the pic of the bikes on the trailer I see some old style tread patterns. Scrutineers looking at dates on them ?

The first ever register event down here I scrutineered. Lucky it was a short bent sprint as over half the entry had been dragged out of sheds and had perished tyres with cracked sidewalls. Some stern warnings issued. Lot of tyres in those sizes sold in ChCh in the next week as they all enjoyed them selves and wanted to do more.  Fun times.

I didn't need the 3 km run up i could see the flags for the speed trap and would open it up then, if i hold that thing on full trottel it would empty both float bowls and lean out, that guy with the red triumph 350 was there,  that thing would do 100mph witch was amazing

Ha. Sounds a bit like a flying quarter down here years back. Fog in the early morning. A mate on an RS125 Honda set what would have been the NZ record if the clocks had a cert. Waited till he saw the traps then opened up. 125mph plus a tad. Dodgy as fuck. Marginal visibility.

On Meth, fuel feed rates become very important the longer/faster you go. The mix we used on a GSXR1100 80/20 meth/toluene uses 20% less fuel than straight meth. Normal float needles but big taps and breathers. 195mph with just under a mile runup.

Those sort of events throw up some odd problems. Very rare that you can hold a bike on full throttle for that sort of distance.  Anyone else there with bikes as old ?

It might for a track day. But if it's in the top of a zip together 2 piece suit, that's not acceptable for racing.

Edit - don't forget, chest protectors are required now too.

As promised. I'd think the pressure plate spacers would be the thickness of the extra friction plate plus the plain steel plus maybe .020-.040in.

It'd be a case of mocking it up on the bench to see if the release mech fits or if the bellhousing needs spacing.

I've got quite a good drawing of how it's done in one of Phil Irving's books. I'll photograph it and post it tomorrow.

Basically you space the pressure plate out about half an inch or less and fit a second friction plate - with the bosses thinned on both. And a plain steel plate driven by the pressure plate spacers goes in between. i was told that a circular saw blade is a good starting point for the plain plate.

If you're limited for space and a better pressure plate, what about twin-plating it ?  Same pressure more torque capacity.

How'd the body hold up Sam ?
