'51 SQ4 - Reproduction Fuel Tank

Before I start cutting and welding, I'm hoping I can get a second opinion or any advice from members with previous experience fitting an aftermarket tank. I just received a reproduction tank from Draganfly for a '51 SQ4. The significant problem is that when the tank is as far forward as it can go, t...

WANTED: Half Width Front Hub 4001-49

I'm looking for a half width front hub suitable for a 1950 SQ4. Willing to pay a fair price and shipping cost to the US. Hub just needs to be serviceable as I plan on refinishing and rebuilding it before putting into service.

Please PM me if you have one available.

Thank You.

Re: Otto Gaskets

While I have not used the Otto gaskets yet...I have sets for a '50 & '51 SQ4 sitting on the shelf...they look just like the composite head gaskets that are commonly used as upgrades on a Commando engine which I have used plenty of. My belief is that the composite head gasket is not reusable. My ...

'51 SQ4 Build Photo

I don't post too many photos of the current projects, but thought I'd share this one now that the bike is on wheels. The wheels are from another SQ4 project that is a few steps behind this one, still a lot of work remaining, but at least it looks like a bike now. Next step for winter work is to get ...

I experienced the same situation as Mr. Falco here in the States; I received two copies in separate mailers both addressed to me.

Re: '51 SQ4 Front Fork Install Problem - Headlamp Ear Length?

Thanks Simon & Simon. Knowing how this assembly is designed to work helped me. I think the replacement rubbers could be half the length and still work correctly. Upon getting the headlamp ears in the yolk, there is a fair amount of compressed rubber in the way. Pulling a fork tube though sheared...

Re: '51 SQ4 Front Fork Install Problem - Headlamp Ear Length?

Paul: Have you got the 'anti-rattle' rubbers and washers (for each fork ear) under the top yoke - and are you sure the ears aren't being prevented from going further into the yoke by the thickness of the paint?

I'm guessing you meant to include a link to a specific section of your blog? I'm looking through that right now, but if you can post the link, I'd appreciate it.
