Well i got a new filter but haven't put it on yet. I'll put it on when i go again this friday (hopefully). I wish i could afford to change the oil and all every time but i can't and quite frankly as a college student i really don't have time or the $$$. Since i don't wheelie anymore or really beat on my bike i'm going to wait till i drag again change the filter before hand and then the oil after that time. Also my honda manual says to change the oil every 8000 miles, and i change about every 3000. So i figure 10 runs at the strip wouldn't be as hard on the clutch as 8000 miles of "normal" riding. I mean if you got 110 passes out of a clutch thats over 800,000 miles if 10 runs = 8000 miles. I also don't burn out at the strip. My tire grips well enough. I'm going to change this next time just to be safe though. Thanks for the info.
Found something interesting though. The filter part of that website seems to no longer work.
As for the oem filter part. I have an oem filter. A yahama filter. Ames has no honda dealership so i had to go to the yami place. I don't want to drive to des moines to get a new one. Interesting thing is that a lot of bikes use this particular type of filter. The r1, i think the 900 cbr does to but anyways there are quite a few. The mechanic said a lot of new bikes all call for this filter. Anyways though it was interesting.
