Sprockets and chains

[Bill Jurgenson]

the Paso chainwheel does fit and with 41t it is a good ratio but it is for a larger chain.
I used these (top quality from AFAM) and turned them down on the outside for the 520 chain.

Folks, Supersprox can and will make you whatever you want, they have US and EU outlets too:

Send them a drawing, an old sprocket for a master, Even draw around your sprocket on a piece of card, VERY likely they`ll already have blanks anyway so just give them a ring. Oh and aircraft grade alloy if you require it for weight saving purposes.
Talon and Renthal too:

Also these fine folk:

In the UK this company is my first choice supplier of all things chain and sprockets:

You don`t need to think about sprockets as only being available in motorcycle stores / dealers, bike builders the world over utilise such companies as those I have listed.

[Bill Jurgenson]

yup,
Since buying that first AFAM for the Paso 1995, I have never ever used an OEM sprocket again, not in the MZ not in the Yamaha nor indeed in any bike.
I get all of mine from Leonhard Sieg.
Claudia's english is OK. All they need is motorcycle model (or wheel if they are different), chain size and number of teeth. Leo has a Skorpion himself so all you need to say is Skorpion, 43 (or how many) teeth.
Or you give them the data:
teeth
chain size
hole Ø
bolt pattern Ø and number of bolts and size.
All are CNC milled from solid aluminum.
Many patterns to choose from but you can draw up your own and he will mill that if it is doable.
He will send by mail within a week.
Like I said, everything I ride has a Sieg chainwheel and almost every customer bike I did, too.
from the heavy Laverda

180º 3-cylinder, 100hp, 190kg ready to go

to the little Mondial

That Lavvy is stunning Bill and far from a heavyweight for one of those. Do I see a TDM front wheel in there?
A good friend had a tuned Motodd Mirage many years ago, some beast and blisteringly fast.
Here you go, just like this one actually:

It might even BE the same bike, it`s for sale in the right part of the UK.
For those interested in Laverda porn, feast your eyes:

Yup, for a Laverda not heavy, tis true, down to 190kg from 245.
nope, it is not for sale nor has it ever been to England. Has been in the same hands since it was put together 1978, originally with Campa mag wheels,
and yes, that is a TDM front wheel which dropped into that original fork with those two TZ250R rotors as if made for it.
In the class one has to run 18" (or larger) wheels, no mags allowed and single pot calipers.
The rear is a 18/4" PVM but I have not been successful in garnering an affordable 3,5" PVM for the front so the TDM will just have to do.
Here a couple more shots.
The PVM rear wheel from the left side with the adapted Cagiva Mito caliper and, above all, the works 3-1 megaphone (not the buyable 3-1, this is a real works setup): what a glorious roar that thing makes. People come running thru the paddock to see if they heard right.

another from the right, the new=old rearsets much farther forward with my own milled steel adapters that have the face serrations to match the frame and reversed linkage. Also the rare SFC gearbox cover with the large oil filler cap and the Silenthektik constant loss ignition. Since it is one of the early 180º engines, it is basically a 4 cylinder less one cylinder and we run a 4 cylinder ignition. There is no flywheel at all, let alone a starter. We made the side plate and ring adapter for the pickup as well.

here under the seat the SilentHektik coils, with 160 mJ at 7000 they amount to arc welders. the ignition box itself is farther back, mounted on an aluminum coiling sheet metal under the seat. Also the 3 36mm Dellortos. the engine is a bastard: bottom end is heavily modified 180º 1000 with much lighter crank from 1977 with the 1200 cylinderblock and head from 78 along with racing cams etc.
A well tended stock triple is good for 100tkm without batting an eye.

Sorry Bill some confusion there I meant the Motodd Laverda in my link might be the same one an old friend owned years ago, Phill Todds creations are few and far between.
Lovely work, and yes I concur those engines are built from girders, VERY strong, proper engineering.

David Hailwood and his lovely family often come to one of my race clubs events with the MV3`s Bill. Gorgeous, simply gorgeous machines and I`ve had my photo taken on Mr Crichtons works rotary Nortons too that also visit most years.
This is the event, (from the entry form):

Would love to see yourself visit one day Bill, I`m a club official so could swing all kinds of things for you.
