Thanks for various replies and it seems that I have probably confused people over my 'methodical' approach to measuring the degree of wet sumping. The table of events is as follows:
1st Drain of crankcase yielded 175ml. Not sure how long it had been standing at this point but the bike had done a run the previous day so not more than 24hours.
2nd drain yielded 75ml which was immediately after the engine was stopped having been run for 10 minutes or so. The crankcase was empty at the start of this test having just done test 1 and it was meant to establish the amount of oil in the crankcase during normal running,
3rd Drain yielded near 200ml after a period of 30hours. The crankcase was empty at the start of this period having just done test 2. Engine was not run between test 2 and 3
4th drain - today yielded 50ml after a period of 24hours. The crankcase was empty at the start of this period having just done test 3. Engine was not run between test 3 and 4
5th Drain (Tuesday 11th Sept) yielded 25ml. Engine still has not been run. Giving it one more day then going to take the bike for a run and repeat the tests.
6th Drain (Wednesday 12th Sept) yielded about 15-20ml. Rate of loss is definitely slowing. Rained today so aborted the proposed ride. Maybe tomorrow. Still confused.
