So... my bike is using a lot of oil lately but it's not clear where its going. The bike starts and runs well, pulls hard throughout the rev range and doesn't smoke.
But its using around 300-400ml of oil every ride (around 4-5 hours) and the oil turns black after a fresh change and new filter within about an hour of riding. There's also some black soot deposits around the exhaust.
I'm guessing all signs are pointing to worn piston rings but is there anything else I could look for or something I might be totally missing?
Thanks in advance
