The barrels have been bored and are now nice and clean inside. I had delivery of 2 new crank pins yesterday so will get on with the crank this week.

After a rebore  barrels have swarf dust all over them and in the ports so the first job is to clean them. You have to coat the barrels first with 2 stroke to stop them rusting when being washed.





Then they need a good wash in hot soapy water this allso removes any oil from handling.





Before spraying I like to warm stuff up it helps the paint stick stops runs and gives a nice satin finish. It all so helps evaporate any water left after washing.





After a spray with the oven switch of now I pop them back in to dry in the heat that?s left / I?m not cooking them remember the oven is on for just a few mins to get warm before spraying then switched of. The heat helps the paint dry faster and helps it from flaking of after spraying.





The warm finished barrels after 1 last quick light spray left to dry slowly on the window ledge. They will be tacky for a day or 2 then I will wrap them up with the crank and get them posted of back to the bike builder.  





The crank is all so now all rebuilt
