I can check mine without taking off the flywheel.On the left side of the engine,like if you're sitting on the bike,take off the cover.It will be held on by 7 bolts.Behind the flywheel is a timing plate.It's held on by 3 bolts.On the right side of the plate will be several #'s and some small marks.Which ever mark is lined up with where the case splits,that's what the timing is set at.That's with an aftermarket plate.
