Title: Smoke signals
Post by: JPaganel on June 07, 2019, 12:50:13 AM: So, I had occasional clouds on startup, which is normal for most BMWs that have one or two heads sideways.

Today, I've been getting smoke around me every time I'd stop at a light.

Crankcase vent is new end of last season, so are valve clearances. The bike has around 60K, give or take for wonky speedometer. It seems a bit early for rings or valve seals to go, but what's the conventional wisdom?

Leaky header/muffler connections?

What colour smoke? Hopefully no bubbles in coolant.

Pretty sure no drips, at least not to that extent. My oil leaks cleared up when I replaced the crank cover gasket, oil sight glass, and all the little rubber mushroom heads under bolts for both covers.

There is some smoke getting out of where header bolts to the engine. More is coming out the tailpipe.

Classic oil burning blue.

Haven't looked for that, but kinda doubt it.

Last night I parked in a cloud big enough that my passenger was kinda concerned we were on fire.

This morning, started and ran all the way to work with nary a puff.

'Tis a puzzlement.

Thing is, it doesn't normally sit for more than a weekend, or a really bad weather day. I ride to work daily.

For a Brick, how would that be different from 30-40 minutes on the highway?

It doesn't differ for a Brick. High revs are la messa a punto italiana during those minutes.
