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???

 

Change the oil and hope it is OK. It is probably fine if you did not detect or hear anything odd. Just try not to do it again.

 

I'd just change the oil as recommended and go from there. Odds are you didn't suck in anything harmful or you would've already known by now, but changing the oil is just to be on the safe side.

 

Your OK if its still running.Why do you guys say to change the oil?I'm not saying your wrong but I do wonder why you need to change the oil.

 

Yes me as well why change the oil?? Thats interesting please let me know??? And tell me how would i know if there was something wrong would i see smoke, rough idle, stalling out tell me,, im freaking out!

 

There's no need to panic. I have known people that didn't run any filter - ever. I have also seen panty hose substituted for a filter. Highly NOT recommended but they never had any major issues. Not running a filter for long periods will decrease the life of your cylinder.

 

If it still runs and doesnt smoke, it is just fine. Changing your oil because of it is a waste of time and oil.

 

I say change it because if any contanaments did get in and survive the combustion process that is where they are now.

Then again I have never missed a oil change on any of my cars/trucks in 17 years. So maybe i am just to picky/paranoid.

 

Thats me as well. Its not like its expensive or difficult to do it and its just an extra security net in the event something may have been sucked in.

 

If changing the oil helps, he's got more problems than running without the air filter.

If you really want to clean out the combustion area, get some Sea-Foam and spray it in there.
