I build engines for a living and have found the best way is a acid dip that has chemicals suited to cast alloy ;)

Thanks Trig. I read about this and honestly wasn't sure what's best. I've got the origional K1 which came with the bike. So the engine ,(K6) in the frame is being replaced. One of the K1 linings is cracked (not stripped it down yet so don't know what else is wrong). Is it Ok if I pm you at some point in the future as I'll be needing your services etc. Thanks.

The K6 to K1 barrels and liners are not interchangeable and the head is different. You will see the differences once you have the engines stripped so, keep all engine parts separate, one on one side of the workshop and the other on the other side ;)

Didn't think so. Already got two spaces in the garage for K1 and K6. Ta pal.

So I found these marks when cleaning the K1 head. The head came separately from the bike (as did the engine) but is this machinable or scrap! Thanks.

A head skim and those valve seats need a regrind, also check the valve guides . Are you sure it is a K1 head ?

It just came with the original engine in bits as the bike has a K6 in it. The bike is a 1971 but not sure tbh. What else will show if it's a K1 or not?

Head and barrels are different on a K1 to K6 ;)
Show me a picture of the head side on and the top face and a front, top and side picture of the barrels and i will tell you if they are K1.
