Hey guys. Another question. I am repairing the top end on my friends 1974 850 Commando. Once I removed the cylenders there was a LOT of oil in the crankcase. Do I need to remove some of it before I put the top end back on and start it up. I believe this is called wet-sumping and how do I correct it??? Is there the possibility of any engine damage?? I also checked the cylender bore and it is great. How much honing is reguired before a refit with Hastings rings?? How long do I keep the rock hone spinning to remove the glaze--3 or 4 seconds?? Or longer?? Can I damage the cyls by honing too much?? Thanks again for all the help you have given---Mark C.
