PE 250T coming together

[Gonzo]

This is my 1980 PE250. She's rebored with new piston. Has 080 stamped in the top of it. Am I right in thinking this is the last rebore size? Also, she's just developed a slight oil leak from the gearbox output shaft seal. Can I pick this seal out to replace it or does it need to be driven out from the inside? Wasn't planning on splitting the cases just yet.
Also I need a couple of parts to finish her off. Speedo and chain guard. Both like rocking horse shizzle it seems but thought I'd ask.
Anyway, the bike goes very well and is a blast to ride.

Yes it is just pushed in should be able to fish it out.

Looks the goods Gonzo.

The oil leak from the output shaft could also be coming from the o'ring that sits on the inside of the sprocket spacer. Number 42 in the image below. Worth a look b4 you replace the seal

Your right about that doc.. buy a couple of them as they are really cheap.  Also look at no.39, the bush, as this can get corroded, grimed up etc.. If it was me, i would just get all 3 parts, the o-ring, bush and seal and no.42 washer, and do it as a proper job but the bush may be hard to get.
Cheers,
Alex

Thanks a million guys. Good info. Those 3 parts and the lock washer are still available so definitely sounds like the way to go.
