OK, I have looked in the manual and it tells the specs of where the chain needs to be, but it doesn't tell what bolts loosen, tighten, etc. Can anyone tell where the parts are or even a snap shoot of which one need to be done. I don't think it matters but I have xb12r. It has just over 8 grand on motor and was going to change the fluid in the case and figured I would take of the chain adjustment in the process. Any help would be great.
