First Restoration :)

I've just started my very first engine restoration - a J.A.P. Model 2A - and I bought a matching pair - so the Model 2S is also sitting there waiting as my next project.

This is what it looked like when I bought it.









In the process of pulling it apart now....

Looks pretty reasonable I guess.

Progress pictures to follow.

Anyone know what this is?? It fell out around the time I was taking off the Magneto plate and the backing plate - I don't know what it is or where it comes from



Any ideas??

Good Photos - Good thread Polybus - I am not a JAP owner but it looks like a valve spring retainer or similar - I would not of thought it came from the magneto as it is too oily!

Hopefully much brigter sparks on here will help!

nice motor, a new condenser will make a difference, - can you use a drill on these instead of the pull cord - i have skinned many a finger trying to pulstart. if not put a bit of thin rubber pipe on the last 3 inches of cord to go between your fingers.

cant remember there being any parts of the jap 2a/s series with these that ive done, maybe from the drive end part of a disengagment mechanism or a "UFO" just some thing that has flow off another garage project and got lost in the tin cowlings until this time ??

Hey - check this out.

Check out the little button he presses at about 0:50 seconds.

I reckon that might be my Mystery Item - I'm off to check it out.....

Just spotted this thread, that looks like the button for the ignition cut-out which should be fitted on the carb side of the engine in the engine back plate.

Pete.

You got it Pete!! I can't see how it cuts out the ignition though - I assume it must short something to the Magneto or similar.

And I can't see how it is fitted - I see the whole where it is supposed to go - and I see the mark where the button used to be, but I can't see how it should attach on there.

YAY!!!    

I took the engine - with pulley attached over to a mate's place - he's got one of the best setups you'll ever see - plus a wealth of knowledge and experience.

We considered all the responses I've had and ended up assuming the pulley was just slid on to the original JAP crank. So we ended up hammering (and hammering....and hammering) a couple of chisels down in between the pulley and the crank case and got not movement

Applied some heat - heard a bit of a "crack" - more hammering and it began to move ever so slightly.

Of course once is started moving it wasn't so tough to get off.

Then it was easy to get the valve gear, the valves and the crank out - the bearing was a little difficult, but came out eventually.

Cleaned everything in my mates 53 litre Ultrasonic Cleaner!!

And now this is where I'm at.....completely apart.









The bore looks OK - but I'll give it a hone anyway - new rings and new bearings - new gaskets - and the carby is going to need some sorting out I'm sure - hopefully I can get a carby kit for it.

But as for now - bead blasting for the cowl and crankcase and start the prep for painting.

I've uncovered quite a few spots of the original paint colour - a kind of pale/steel blue - a metallic shade - I am thinking of doing it with GALMET Hammer Finish Reef Blue - seems a reasonably close match to the original - but how will it handle the heat?

I will probably do the crank case and cowl the Hammer Finish Reef Blue, but the barrel heat proof matt/satin black and leave the head polished alloy.

Now - just to get it done.

Very happy!!!
