1981 GSX1100 Katana Based Project

That's completely normal. I usually put blue Hylomar under the copper washers to prevent leaks.

Yep, not unusual and Plan A was to use a sealer but when my mate offered to mill it I wasn't going to pass on that deal.

Even if the surfaces are good, I still put a thin layer of Blue Hylomar under the washer.

O.K. another step completed today. The head bolt posts have been milled back to new and the head is now ready for the new valve guides, seat cutting/matching valves and new valve stem seals to be installed. The same workshop is boring the barrels for the new pistons.

I will be interested to see how much lighter the 1135 barrels are when they are bored to 96 mm for the 1197cc kit. As stock they weigh 8,080 grams.
