Has anyone experienced poor or inconsistant shift quality from their 06 R6? I know they have had problems in the past but I'm not sure if the gearbox has been sorted out yet. I noticed it more since my first oil change where I put Repsol Moto 10W-50 in it, and I do not know if they come with synthetic in them. It really shifts like shit up and down when cold, but I figure that's normal. Now when it is up to temp I still have problems mostly when downshifting from 4-3 or 3-2 gears which can really screw things up royally when cornering. Any input will help in regurds to synthetic oils, or experience with the infamous Yamaha gearbox. Thanks.
