    Cam Markings on 2017 250 SFX

    Figured it out. I wasn't at TDC. At TDC the two "paint" marks lined up nicely at 3 and 6 o'clock right at the engine case. My guess is the factory put those "paint" over the markings on the metal.
  2. Was able to find TDC but don't see any markings on cam's. Just about every video online has visible cam markings. There is a painted mark on each cam but would think there would be something from the factory. Maybe the dealer painted over the marking. Also the paint marks are 180 degrees opposite of each other, but at TDC are at a weird point, about 1 oclock and 7 oclock. Also how do you know if you are at TDC compression? The front cam lobes (exhaust?) are facing to the rear of the bike and the back cams (intake?) are facing up. Any help would be appreciated. Thx!
