[QUOTE="Matty, post: 134118, member: 1339"] Hi My Comet usually did about 200 miles per pint when I first bought it in 1956 and the Phil Irving hand book stated on page 95 this was the expected consumption so I have never worried about it. This or 250 miles per pint or more was the norm even after a couple of rebores and valve guide replacements over the years, and the engine was always mechanically very reliable though it was often hard to start until I changed the plug even after a fairly hard run - but it always smoked a bit. So a couple of years ago Conway motors fitted an oversized sealed inlet valve guide and new inlet and exhaust valve, mainly to stop the Oiling up. I consider the problem now fixed at 600 miles or so to the pint and with little smoke and starting excellent. I have two mags - both in excellent condition with bright spark condensers so any starting problems when hot are not the traditional hot condenser problem which I have had several times before finding the "brightspark" fix. So how do you get 5,000 miles per pint of oil when I get 600 with my modern Vincent spares low expansion piston and 2.5 thou clearance rebore, new guides, the cylinder lubrication feed blocked and a fairly hard run in to avoid glazing? It's a puzzle - but no problem. Matty [/QUOTE]
