There's no VAT (17.5%) added to items sent outside the EU, although of course for some countries, there could be import duty to pay when it arrives?

CLeaned these up a bit. They still were a little greasy. Need to finish the gearbox before the inner can go on. Luckily the alternator studs are still attached.

Are those hairline cracks radiating from the center stud hole on the backside?

Typical evidence of former improper spacing of the stud/case clearance AFTER tightening the 3 main crankcase screws. Worse examples also exhibit cracking at the 3 screw locations.

Good eye. But if you are familar enough with the cracks back there you already know that they are just the casting marks. :mrgreen:

OIL TANK

So I started the next part, the oil tank. I pulled out the fuel tank and seat and started to see how it'd fit together.

First good news is that there is plenty of clearance for the headsteady (which is still unfinished but let's not go there...)

The traditional Proddy mod is to trim or fold over the top seam of the oil tank. What I really need is to get all the mounts (fuel and oil tank and seat) and really see where everything will sit.

Oh, and if I am going to mod the way the oil tank mounts. I hear the stock setup is less than desirable.
 
Re: 72 Combat Proddy Build- It begins...

I hit a few parts with some spray paint. The ends of the center stand mount where left un-powdercoated so I touched them up. Also the side cover mount.

And I need to start thinking about the oil lines before I get too far.

Does someone have a clear guide on which lines go where? Hey, let me answer my own question...

This oil line diagram is a good guideline and is pretty much all you or I need, but I wish i could see it in the early 72 version.

Preferably this general area.

I'm pretty sure it's exactly the same aside from the oil pickup location. Routing of lines, etc. is identical, I believe.

Where is the sump filter? Do you mean breather or the oil filter?

I believe it is on post-72 engines.

The sump filter was deleted only on '72-'73 750 crankcases. '68 to '71 750 Commandos and all 850s have them. The logic being combat engines wouldn't last long enough to require a sump filter??? My combat has >46,000 miles.

Done
Gee wilikers, Dave. Your the last one I thought would acuse someone of highjacking a tread. :lol: :lol: :lol:

For the life of me I'm going to beat this dead horse till its gone to dust and floating in the wing.

I want a picture, or 4, in detail, showing the exact area and location of the oil pick up on a modified 1972 crankcase.......please.
Don't tell me to go here or there. If ever I can return such a demanding favor, I will GLADELY return it. Even if that mean sutting the hell up. I will......for a while anyway.

Can I tell you to start your own thread. How is that for telling you to go somewhere? :mrgreen:
