I have wondered about those other bolts? They sure are burried under there. Have you ever wondered if the bike is starved for oil for a split second because the frame has been drained? Many people have said that a significant amount of wear on an engine is during startup. Just a thought.

I drain the frame and crankcase each time, check and clean the filter every other time. Whenever I check the screen in the frame its spotless. Unless more debris than normal begins to show up in the filter or magnetic drain plug I will probably only check the screen once or twice a year. I only drain the oil after its good and warm. I want all of the debris stirred up and suspended in the oil.

Are you draining from only the big crankcase bolt and the lower front frame bolt?

I remove the frame drain bolt and the large drain plug from the bottom of the motor.

I don't bother with the screen except for once a year. I always take out the frame drain bolt, and the large and small crank case drain bolts (I don't bother with the oil filter drain bolt anymore as nothing ever comes out anyway). I know it's a small amount of oil, but it makes me feel better and doesn't take much time or effort as I usually have the skid plate off anyway to clean under it.
Your interval sounds about right. The way I look at it is that the 450 is a big motor with a very small oil volume. My son's TT-R90 has 800cc versus the WR ~1000cc so the WR fouls it's oil pretty quickly. Remember that a lot of engine damage occurs not only from metal particles, but from all those nasty combustion bi-products that end up in the oil which are very corrosive to engine parts. That's another reason to always change it warm: to get as much of the chemical contaminants out as possible.
I also change my oil filter every other change.

Oil paper filter every third oil change
Indy, why do you not use the Scotts s/s oil filter? Alot of the other long time riders seem to be useing them and I am somewhat suprised to find out that you use the paper filters . Hope to see your reply soon for nothing more than to satisfy my curiosity cuz I have thought about getting 1.

Mike where did you get the magnetic drain plug for your 450?
Zip-Ty makes one. The one for the YZ's or the Wr250 will fit.
