Race chassis

good old bum centre lol , i like that bike , now i need to make one

[husaberg]

Yes i did a horror meeting my worst ever.
Magneto shit it self maybe a little to much material removed or because.the bearing was on the way out.
Someone lent me a stator and rotor.
Rode it for a bit but it was hammering it (the borrowed bits). I don't know who lent it to me either but thanks whoever it was.
Mag side main had let go.
These maladies were i believe related.
I had left a lot of bits on the coast.
The old man did the 600km trip to bring them over.
Mike the "greenman" i believe won so he keeps er... reminding us

Below the Quantel Norton

I believe it may have won A BOT Daytona event later on or was second.
Norton had a big problem with the engine it turned out as well as costing them huge money it had so little flywheels it would allegedly lock the rear wheel on overrun and had a water pump that was supposed to be impossible to bleed without burning or scolding the mechanic

I am sure some pics of the bikes or engines have been added before a British attempt at a prepackaged Rotax tandem twin TZ beater from the 80's made in both 250 and 350cc.

Lozza will be well aware of this When i was looking for pics his name pops up quite a few times.
One thing i have not picked up on is they had mirrored disks on at least one of the bikes.

but was it mainly for a better transfer layout with more symmetry as well?
Possible advantages with the twin disk i can see include a symmetrical flow and the inlets would be smaller so less obtrusive to the transfers.
It should also possibly offer better drive-ability( it does of course fail the KISS test though.)

It went pretty well, Exactweld, they go back to the 80's , Gary Noel won the European Championship in 1984 on one

Here is the Story of the Quantel Norton and some more Exact weld pics follow the arrow after the husaberg for the articles.

Have a good look through here a group of artists at work.

Wow that's quite a lot of work. Not much width to do much else.

This was on EBay today.
Starting 1000 usd. funny enough they also had a set of WP USD forks starting at 1000USD

That's never made it out of the laundry. The bolts are plain bolts but he looks & the milled lines on the linkage don't have blow-back in-grained in them. I doubt you can get a carb out of the gap hence the removable subsection, but that would be a bit of a wind-up as you're pulling in two different plains to get it out. Might work ok in practice.

Just goes to show how little space there is in there. If the thin part of the shock meant you could slide the carb out I'd have to rescind my comments, but that is critical, you can't be removing the shock bolt and propping the bike up every time you want to do jet change. Looks like a big gap, but its hard enough with the std setup.

A watercooled KE100 might fit.

Now there you may have a good point. Still you'd have to trust matey designed the linkage with some Foale or Bradley formula as that stuff gets funky real quick.

An alchemy style linkage would work. I was thinking that the other day looking at a old pic of Phil Payne's bike.
this is obviously not it.Not so sure it wouldn't get in the way of the rider though.

[F5 Dave]

Yeah I'd kinda thought about Alchemy (ex pat, can't remember the name) but they use engine as a stressed where that shock pretty much needs (apart from its fairly unique length) to be where the frame spare or the tank is now. Non starter really despite being kinda cool.

The Ex pat was brook Henry, i can't remember who did the linkage but he was at uni at the time, (aiken?) and was a Kiwi to Ken Mcintosh but them onto him.
The way i look at it the Supermono had the same set up as the NF4 and nobody seemed to complain about it.
It just irks me how much it is in the way.

Husa - google Spondon RS125 for another variation. Quite clever and maybe applicable to an early RS.

i can find them but can't post them.....

[F5 Dave]

oh yeah looks pretty similar, but I'd guarantee those frame spares are wider than NF4. RS had carb offset a bit to side anyway.

Meh build it & ride it.
