how much oil

[crooky]

Just looking for a bit of advice. Scoot has been throwing a lot of smoke out I fitted a drivesideoil seal about 2500 miles ago loads of smoke. I've checked the breather is clear and it stops if I cover the exhaust and didn't quicken when draining the oil It's been dynoed and smell isn't two stroke I decided it must be the coverplate so was planning on getting one of the steel ones from mb. My issue is that I drained the oil and there is nearly as much as I put in 2000 miles ago maybe 50ml used but surely it would have used more than that. Surely it would have used more than that I use it daily and it was smoking on the way to brid. Any advice much appreciated I was wondering if it could b oil in the exhaust from before. It's a series 2 with Japan conversion Sr 190 thanks
