My TW seems to use much more oil when run flat out. I am going to open the motor to check the bore & rings but am wondering what others find as normal oil consumption.
My bike has 22 000 km (14 000 miles) on the clock; much of it touring on gravel roads. I have just abandoned a planned long solo trip through some remote areas because on the first day I used 500ml oil (1 pint). It had been only 250km (160 miles) of mainly at 90kph -100kph (50mph-65mph). Next day going home was on gravel so speed was down & I used hardly any oil. I have found this before that it uses oil when running wide open continuously. My last long trip I went 450km (280 miles) the last day & the oil was below the window when I checked it afterwards and very little oil drained when I serviced the bike - this may have contributed to the problem & it had happened earlier in that long trip.
The bike leaks a little oil. I replaced the left gasket & the outboard bearing seal before this trip because of that leak. I have a 3mm (1/8") bashplate under the engine which had sand & dust stuck to it so I never established where the oil drip originated before I fitted the new gasket. There was a small drip (I think-it could have been an old one but I think not) after this aborted trip. I washed the bike & there is no oil leak since then onto the bash plate. All of this makes me wonder if that oil had not been blown out through the crank case vent.
So my questions are:
1. Do TWs blow oil out of the crank case vent if the rings are worn?
2. Do TWs usually tend to use significantly more oil when run flat out?
3. Any other input would be welcome.

On another related point.
I made & fitted an oil cooler. It works excellently; can feel the difference between the temp of the pipes to & from the oil cooler. That oil is the feed to the gears & outrigger bearing (crank shaft & cam shaft have separate outlets from the oil filter chamber). That oil flow has stopped as the pipes do not get hot any more. I have cracked the banjo fittings on the filter cover & oil flows freely. I had to cut & tap threads in the oil cooler at home without an airline. I am assuming that some swarf has blocked the oil passage downstream from the oil filter cover. So I have to open the engine to sort that out.
