For fuel mixing, what I find easiest is to put 100 cc's or 100 ml's (same thing) of oil into a 10 litre petrol can. Then if I want 60:1 I put 6 litres of petrol in the can, or if I want 70:1, I put in 7 litres of fuel. Dead easy, and no trying to guess small quantitites of oil between the graduations on your measuring jug.
The 270 is definitely more snappy than the 280 and as a consequence is much more likely to spin the rear wheel making it very difficult to ride in bottom gear which is, I believe, a lower ratio than in the later bikes. The 280 has more grunt. You can play with the timing on either to soften or increase the power and response.
If you ride mud, I'd choose the 280, but with one caveat. The 280 TXT air filter arrangement is not very clever and could let mud straight into the airbox if the protective flap became dislodged. The 270 has a single piece rear mudguard and didn't have this problem.
Digging holes, making mounds, etc could be construed as development and could bring the planners down on you, let alone possible grief from noise complaints and so on. Rent the land out for horsiculture, put your bike on the trailer and use the rent you receive to pay the farmer near Broadway (that you mentioned recently)
Inside the slave cylinder piston there is a spring and inside that spring there is a guide pin. If that pin is put in the wrong way round it can prevent fluid returning when the clutch lever is released. Maybe this is your problem? Good luck!
When I had a 2000 TXT BVM Moto fixed me up with some Dzus quarter turn screws to replace the allen bolts that hold the seat unit on. These made life much easier. Shame they don't do something similar for the Pro!
Gefrees is in the former East Germany, not far from the Czech border, but I don't know if the terrible problems affecting southern Germany have spread that far.
Found the two locking rings on top of the spring on the Ohlins rear shocker had come undone and nearly wound off the thread. Can anyone tell me what the basic starting position should be in terms of position on the thread?
Before I started playing with the pre-load on my 04 Raga I unscrewed the top locking ring to determine the standard setting. It took 19 whole turns to remove it. Hope this helps.

Why can't you measure the circumference of the wheel and tyre, or measure how far it travels on the ground for a complete revolution?
