Chain adjusting: Where do you measure from?
When adjusting the chain I've always been told to never trust the hatch marks on the swingarm and to measure both sides of the adjuster off of an equidistant point on either side of the bike. Usually you can measure off the swingarm pivot point, pegs, something like that. The versys has an oddly shaped rear and I can't determine a good point to measure the chain adjustment distance off.
My current thought would be to check it based off of the rear spool locations, since they should be located in the same spot on both sides of the bike.
