Had Singh's experience with the process, oil filter, screen, draining everything possible, buttoned the lot up with new filter, added 1.6 liters of 20w50 oil, with bike on center stand, level popped up to middle of sight glass, cool. Fired her up to circulate the oil, let run for a few, shut it off, let it settle, oil now at bottom of glass, lower than low level, called it good pending hard ride, 2100 miles on the clock. With extra oil on board, went for a ride, about 6 freeway miles, speeds up to 81 indicated. Stop to check the oil level, assuming I had nailed it only to see a pool of oil forming under the bike. Usual seeps under kickstart shaft, all drains and pugs dry, only to find oil dripping from the air box!! WTF!!. It was dry with the oil at the top mark when hot before the change after really hot, hard riding in 95-100 degree heat and long 5-6% graded terrain,oil level now when hot just above low level, everything should be cool! Wrong! Any ideas? I plan to remove the air box cover and see whats being pumped up the breather. I had a previous air box oil problem from dealer's work, so I was aware of the issue, tried to avoid it but Murphy wouldn't comply. Thanx upfront!
