As the title suggests I'm looking for a set of Seeley Mk3 engine plates for a Commando engine, as its probably unlikely I will find any plates some templates would do nicely. TIA

Hi Mart
I'm not sure if I have a template of the Mk3 I will look but it maybe the Mk2 I'm remembering.
I am stripping my MK3 at the end of June for painting & can copy them then.
All the best Chris

Hi Chris, thank you very much, thats appreciated. Mk2 don't seem to be a problem but noone seems to have Mk3 templates.
Thanks again

It might be worth giving Andy Molnar a ring? Or perhaps Minnovation racing?

But more to the point, whats the story behind the project in your avatar? In fact, don’t answer me here, why not start a thread in the build section ?
 
I simply did the cardboard and hand-held jigsaw trick. You need to get the motor as far forward as possible. Also the cables to the carbs on my bike are wearing the underside of the fuel tank. The height the gearbox sprocket ends up at, is probably the only problem you might encounter. Engine plates are easy to make. And you get a sense of achievement if they are good.
The MK3 Seeley is lighter.than the Mk2. I use a curved gusseted bit of chrome-moly tube in front of the motor. You need to be able to get the head off while the motor is in the frame.

Yes if it really comes to it I will make them myself but being a 'production' frame im hoping there are some kicking around somewhere.
 
Molnar builds ‘em. Minnovation build ‘em. And they’re local. Hence why I’d ask ‘em.

There‘s also Kenny NYC Norton of course...
 
Everyone has their favourite position for engine and gearbox. If you can,contact Roger Titchmarsh, as he had paper templates that he supplied when I bought my first Seeley Mk3 from him in the 80s. I moved my engine forward and tilted it back slightly from standard, and moved the gearbox back so I have to use a 1000mm belt with Maney primary. My cylinder head sits higher in the frame, so the motor has to come out got anything more than setting the tappets or changing plugs, but it only takes 20 mins. If you have to take the head off it's better to do it o the bench anyway, no matter what some "ex spurts" may tell you

You take your bench to race meetings ?

I haven't had a breakdown in 30 seasons racing that would have needed the head to be removed, not so much as a fuel line come off due to piss poor preparation. If you need to take the head off, the circuit is not the place to do it.
Build your bike with proper quality parts, race it properly and you shouldn't have any problems
Also, you won't have any problems if you just leave it in the shed for 30 years and just bullshit on the internet about it

Exactly. There are those repairs that you do in the paddock, and there are those repairs that require a tactical retreat to the workshop! Well, at least if you want to do things properly.
