Looks like Liberty had a prototype a few years back, they were keeping quiet about. :lol:

This is a classic, we need to put it in the gallery!

is that an Amal carb on that thing?, I'm going to be really upset if I find out that Liberty made a Durable float for that and they won't make one for the baby Linkert that came on a Harley Hummer!

but they spelled the name wrong when they lettered the tank.

still dripping,

C'mon good Fellows!

Cotton was a fine British marque.

I have found Brits in general to be enviable for some genius, like sludge traps and such, but I would be an even greater fool than I am to work on things that my wrenches do not fit.

But to prove that I can be a consumate fool, I have a BSA frame cobbled to a hardtail waiting the Janitor's Closet, with an A10 (whatever that is) tranny that should fit nicely behind an Indian 741 set of cases. With a set of hybrid shafts from Denmark, and a set of (ugh!) sp*rtst*r flywheels with some Mahle pistons the thing could reach 50+ cubic inches. Add Betor forks, Honda wheels, a mechanical disc brake from a go cart...
and yes, you could really call it a "prototype"

The gliche so far is that although Shifty can stick anything ferrous together, the aluminum 741 cases have so far confounded two experienced professionals with TIGs.

The last Cotton I saw in real life was being pimped by Bollenbach at a D-port Meet.
He never had much use for me.

Is that another version of the "F" head?

Actually its just a plain old sidevalve. You can't really call it a flathead because, if you look close, there is NO head.

That's a JAP engine (not Japanese, JA Prestwich Industries), the cylinder was cast with a blind bore hole, the 2 threaded plugs over the valves were for removing and installing the valves.

First Cotton I ever saw that didnt have a (gag,retch) Villiers two stroke in it! Very neat.Admittedly I havent seen many Cottons .Cotten what did a Sportster ever do to you? I have run,raced and abused XLs for many years and developed considerable respect for the early versions(70 and back).I have also made good money fixing them and they are a breeze to work on.

Interesting, looks like they may want to Scotchbrite the piston before putting her back in service. I'd like to see how the valves work. Does the valve access hole reduce the compression ratio or does the plug fill all the way down to the top of the combustion chamber? Mike

XLs are fine. Its the loose nuts on the handlebars that gave me grief.

As a business owner, they (sp*rtst*r owners that is ) were toxic. You could always count on them to run the employees in circles ordering parts by the wrong number, begging for charity, whining about the tab, and all too often stiffing me after all.

I shudder to think of how much dead XL hardware I have left over from the '90s.

Only a sp*rtst*r would show up for a "tune-up" without a kickstand.

The last time I liquidated an estate, a full haywagon of XL scrap, including titles, barely brought $2G. One rolling basket had to be held back until the paper was found. Silly me, I gave $400 for it. I later signed it over to an employee to get it off the property.

If XLs had any redeeming value at all, it was to keep Big Twins safe.

PS: I have a Famous James with a Villiers proudly gracing my showroom window.
