 A bit boring was it. In France, if I'm in the mood, I'll stick to the 90 kph speed limits and amble along and the best I had was 73 mpg (3.9 l/100km).Â

Naw, not boring. Driving with my girlfriend, whose risk estimate on bumpy, curvy roads is a bit higher. But the view was really great, a cool, cruising day with a grin on my face :pimp:
The next day we split up as I had a meeting sceduled and I compensated to get there in time, blowing out all the deposits from the slow run....
Found the source of the 850 running hot...... the twin horns i just fitted seem to be working in conjunction with fork gaitors to stem the flow of cooling air to the radiator !
After finding that my mk1 was losing oil through the oil tank breather hose at high revs (oil on the back wheel !)Â Â Â I found that the breather hose on top of the gearbox actually has an underpressure (slight vacuum) so i connected the oil tank overflow to the gearbox breather and went for a 'demanding' test ride.
Â
Does anyone else have a lot of crankcase gasses getting into their oil tank......if you put your finger over the oil tank breather do you get a lot of gas blowing out, especially at higher revs ?
Â
This was exactly the same situation before i rebuilt the engine too, so I don't think it was as a result of anything I've done in the rebuild.......there just seems to be a lot of gas being returned to the tank with the oil, as if the dry sump pump is gulping oil and gas from the sump.......with so much splashing going on in the tank a lot of smaller oil droplets seem to have been getting blown out of the breather with the escaping gasses.
Â
Being a 360 degree twin, both pistons move up and down together, so there is compression and release of gasses in the crankcase on a larger scale than if the pistons worked in opposition.....you can feel the effect of that at the main crankcase breather hose where there's a lot of pulsing

Looks smart Steve. Does it sound well ?
I had earplugs in as usual, and the baffle in the can.
The sound varies greatly depending on RPM and throttle position. At ~3,000 and steady there is no noise getting thru'! @2k there's a crackly rasp. Going for it sounds a bit like a Harley at times. M9 cruising gives a muted buzz sound heard from the seat. I haven't asked any passing motorist or biker yet!
I pulled the plug out on my return so will try that tomorrow.

full interprise (without separating) and flanges left very easy.
fuel tank, carburetors, intake manifolds.
I had already removed the head cover and the 6 nuts holding the head to the cylinder.
Today after some time, I found the two long screws (allen), which are close to the chain of command.
The head took a bit to get out and I had to use a cable tensioner to push it. Fast and without problems
I had no problems with any screw. All they left without eventualities.
Tomorrow after work, I clean the parts. Yet this week will bring the head to assessment by a professional grinding. The laps of intake side were marked and generated fine swarf. The lubrication holes were restricted.
I am optimistic. But I am also realistic, we will await the opinion of the professional.
