Tore my 06 yz450f down today to grease the bearings in the connecting rod A-arm and swingarm. After taking the sleeve ouy of the connecting rod to my suprise ther was no string cheese around the needles and after taking the collers out of the A-arm no string cheese around them neither:naughty: .Yamaha must have forgot to put the cheese in ! Iam still in the process of greasing the bearings I stiil have the swing arm to do:cry: . I'll get to it in a few minutes and see if they forgot it in the swing arm to. Is this a mishap on yamaha or did they quit using the cheese:confused: ? I'll keep everyone posted on the swingarm.
