have an 06 sxf 250, I had to remove the right inner (clutch side) engine cover. As I removed the cover the water pump shaft (which also is the bottom timing chain sprocket got moved a few teeth off because I was tired and not really paying attention. I am in the process of trying to figure out how to reset the timing on it. As of now I set the intake and exhaust cams so the two dots align with the horizontal line on the cylinder. I am trying to figure out how to make sure the crank (piston) are in the proper position in relation to the cams. My son and I have quite a bit of experience with 2 smokes but this is my first time inside a 4 strk and just want to make sure I don't make an expensive mistake.
