Took the Honda to my son’s house in PoCo this morning to watch the MotoGP. Man, what a race!! Marc Márquez is the man!!

The Honda ran a treat. Had it up to 60mph, or so the speedo said. It felt like it. I reckon I’ll be riding it to coffee on Wednesday.

I’ve followed Moto GP for decades, even riding to Laguna Seca for at least 10 occasions from early 2 stroke 500’s to the Rossi days of power.
Marques does appear more at home on the Ducati after a career on Honda. Good to see.

So I’m getting quite a bit of white, milky foamy stuff on the underside of the oil filler/dip stick. I know this indicates water in the crankcase. What could be the cause? What might be a remedy?

The bike sat for many, many years. I drained the oil, new oil and filter. Could it be residual moisture from its long sleep? It was very probably put away wet and forgotten.

This afternoon, after riding to coffee I pulled the plugs. #1&2 looked a bit rich, #3&4 looked a bit lean. Turned the air screws out 1/8 turn on 1&2 and in 1/8 turn in on 3&4. Try it again tomorrow maybe.

The whitish buildup around the dipstick is a clear sign of the engine, and the oil, not getting up to temperature enough to evaporate the residual moisture buildup from multiple short trip runs. The machine needs to spend minimum 1/2 hr out on the highway, it will quickly disappear.

Ya, that’s what I’m hoping. Thanks Steve. BTW, after a couple martinis I posted a song.

Thinking of getting a Memphis Shades Classic Deuce windscreen for the CB750. You forget how much grit hits your face when you’ve been riding behind a windscreen for years. Had the Classic Deuce on my Kawasakis. Not ideal in terms of aesthetics, but effective.

I've ridden with a windscreen of some sort on all my bikes after I was riding my Brand '68 New Honda 450 on the freeway, from Chilliwack to Burnaby. Intercepted a BEE or WASP heading in the same direction. SPLAT, right in my bare neck. Swelled up like I had a GOITER. Took a few hours, lots of wet cloths and a few aspirins to take the swelling down enough to feel up to riding back home to Chilliwack. Lessons hard learned, are well learned.

Thanks Howard. The one from D2 that I might be interested in is the A33. But I think it’s a bit bigger than I’d like, and I’m not enamoured of their mounting system.
