Well, I've discovered one thing, there is nothing that is not covered in this forum. After I posted this original question all I had to do was start going back thru "Old Subjects" and found everything I wanted to know. I would like to add this to all of you on this oil change thing. Like I originally said I drained the oil, changed the filer and added two quarts and had the puke problem into the air filter so I spent a little money and drained the oil from the bike, refilled with 1 3/4 qt. of oil fired it up and rode it for a while, drained the oil,, ha, 1 3/4 qt. of oil drained out and no oil being blown out into the air filter, I don't know about you but oil is cheap insurance, I plan on changing it every 300-400 miles, and the heck with synthetics and checking the dip stick. I'll change the filter every third change. The 2.24 ltr. (what the manual says) thing must be when the engine is originally filled. I don't know about you but I can't tell what's on the dip stick when the oil is fresh and I'm not going to care any more. With changing the oil every 400 miles I will have the confidence that all is well with the thumper...
