hey guys i was doing some work to my 06 yzf 450 i was im the process of oiling the airfilter and i had put the seat back on while i was doing that then i went into the house for a min or two to grab a bite to eat and forgot that i didnt have the air filter it and and rode it around the yard for about 15 min.. i remembered that it didnt have an air filter and i freaked out!! I thought i ruined my engine... I wasnt kicking up any dist or anything the ground was really wet.. So did i do any harm to the engine or do i need to do something i runs fine what do you guys think???

 

Besides the dust, there is the issue of running lean! Without a filter, it passes more air and that makes your jetting off. Lean means hot, and hot can melt things like pistons.....

 

Chances are good, that nothing bad happened. Things happen, dont lose any sleep over it.
