Sorry folks I haven't posted in a while. Guess i didn't need too 'til now. I took off my SE air filter the other day and I noticed some dirt covering the butterfly valve plate on the throttle body. I checked the air cleaner assembly and found no evidence of the dirt getting through anywhere. I also checked the air filter for holes and found none. This was fine dirt though and the SE filter looks "thin" too me so I am just thinking that it is letting some fine dirt past. Just wondering if anyone else has had this problem?
