ThanX for all the good advise. Before I re-install the smog devices back on and run to the "friendly dealer", I would change the oil with accurate amount (2.2). I would than start monitoring the level again. ThanX again, Yuki The key to checking the oil for comparison is that the parameters are the same. For example if you idle your bike for 5 minutes, shut it off and check the oil level after, say 30 seconds. Do that every time. Do not compare that reading to one after riding for 30 minutes.
