Great day out today, 250 miles of twisting back roads and came home just short of clicking over 6000 miles. Oil in airbox - 100mls or so drained after the run, a bit down from what it has been but obviously not the magic bullet. General performance - it does seem to run more smoothly at low revs (but maybe i just it want it to feel like that), and the idle has dropped from 1600 to, usually, 1300 although a couple of times it stayed higher. Gripe - steel chainguard broke at the front mount. Nothing unusual i believe but i don't much like the look of the CF one so surgery to be arranged. Edit - i am still running the original shorter dipstick, oil level just on the stick at the start of the ride.
