Hi Ted Flash,
During my recent head rebuild, I got the guys to reface the gasket surface and I fitted a solid copper head gasket. I have had no indications of a leak, so I think that is OK. Berger, that idea crossed my mind today. I will cut off the rocker oil supply. If that fixes it, I'll know in 2 minutes without riding it. I suspect it won't, as I have the original banjo orifices (orifi?) of 1.14mm (3/64"). The guides are cast iron, so some inherent lubrication should avoid any troubles.
Today, I rode it 42 miles to get it inspected for Club Rego. I rode it down the driveway, and I looked back after 50 metres and a huge pall of white smoke would mean that any cars following would have to creep through it slowly. Thereafter I saw no sign of smoke. The missus said that it was white with a bluish tinge. No sign of oil from breather outlet either. Upon returning, I wiped my finger in the mufflers. The RHS was quite dry, but the LHS was oily and black with carbon (very dense like carbon-black) but the oiliness was quite thin, like the oil had been diluted with fuel. Any chance that I have a pinhole between the float chamber (LHS) and the inlet duct.?? Any fuel leakage would favour the LHS cylinder. Grasping at straws now I know and the smoke would not be white!! The left exhaust is showing a blue tinge, whereas the RHS is a light straw, so maybe a bit advanced on the LHS.
It ran well above 1/4 throttle, but the pilot circuit needs some tuning - a bit of spitting when hot.
The old rings were not broken but have been replaced with Hepolite rings purchased from SRM, so definitely not a broken ring.
Dutch for the next few rides I'll take your advice and not look back. Swarfcut, I'll forgo the bragging rights if I can stop the smoke.
