The overoiling problem on my 350 Clipper is still happening, all the checks given in my previous post have all checked out however, to be sure, I have on ordered a new oversized 0.040" piston from our hosts and I will have the barrel re-bored to match, also new set of oil pumps. As mentioned in my previous post the cylinder head has new bronze valve guides and new valves. On reading through the various topics I came accross one from Paul, (The Bullet Whisperer) where he discovered after going through and checking the the known points that the over-oiling / smoking problem was due to a bent conrod causing the rings to line up. I have attached a photo (1st attempt, hope it works when I post the topic) which shows oil appearing on top of the piston at about 10 o clock, this is after kicking the bike over for about 50+ kicks, the piston head gap to bore is closer at the oiling point than the other side and if I push it too the other side it returns to the same position once kicked over, I have also positioned the ring gaps away from the point of the oil appearing. Paul mentioned that the conrod can be straightened without stipping the engine. I would appreciate if Paul, or anyone else, can give some suggestions on how to check the straightness and how to straighten it without stripping the engine. I do have a Lazer beam used for checking the rear wheel sprocket alignment. I will post and hopefully the picture will appear Regards Stuart http://s36.photobucket.com/user/clipper132/media/re2/SAM_1937_zps7beqxzol.jpg.html?sort=3&o=0

Looking at that picture it could just be the gaps in the piston rings have lined themselves up.
