Thanks, BigDog. Just coming up on the 1000 mile oil change and its time to order a filter. Been eyeballing the KN 151 for the Sertao on ebay . When I changed the oil the first time the bike took 2 liters and 250 ml (250 ml=1/2pint) to get to the upper mark on the dipstick warm. Figure having to add the additional amount of oil because I pulled the bike upright of the sidestand while draining the oil? Just passed 900 miles on the odometer today. Bike seems to be running stronger every mile, I think the exhaust note has changed a bit too. Really impressed what this great little bike can do- on and off the road. Got a good bit of power improvement from this boosterplug http://advrider.com/forums/showthread.php?t=841919, courtesy of the "Wuka King"since I installed it at 300 miles. Thought I would miss the 105hp of my Triumph Tiger 955i a lot, but to the contrary I enjoy riding my Terra way more. Tons of grin factor.
