Has any body checked the oil used on their twin . I have no oil leaks apart from the crank case breather to which has been extended to the rear pillion foot rest hanger cannot seem to seem to stop oil from leaking out when stopped about 1 inch dia puddle on the road. I have routed the breather pipe under the engine. would it be better to go upwards with the breather pipe but the route would not be easy . For the last 5000 miles i have been using fully synthetic mobile one 0/30 with the high content of ZDDP with no restrictors in the barrel feeds and no metering wires in the rocker feeds. no smoking on the over run or normal running . would you say that 500 miles per pint is ok . I think most of the loss is going on the road via the breather any ideas

I have just changed my oil and put Castrol Classic XL 20/50 in my twin, I haven’t run it yet but wondering if it’s too thick having just read these threads. I live in the colder north so maybe should have used something thinner.

Hi I dont know what the bench mark is for a cold start is mine Yesterday was 8 seconds from firing holding a fast tick over to see the oil return start ,. only when it starts to tick over say more than 2/3 mins that oil starts to comes out of the crankcase breather when it is revving more than 2000 or so I cant see any oil
