just changed the oil in this four stroke monster.found metal crap in the filter area. can any one tell me if this is normal. bike runs good. also i noticed white carbon build up in exhaust chamber as well as the header pipe. the header gets red hot which from reading all the informitive forums appears to be normal. i just want to make sure this isn't a lean carb condition. thanks !!

Sounds like a normal 426 to me. The carbon at the exhaust tip might be more preferable at a light tan than white, but if it runs good, don't sweat it.
