Hello all, I am building a 2017 RMZ450 and have come up against a problem: I set the crank at TDC and set the cams so the marks are at 9 and 12 for the exhaust cam, 12 and 3 for the intake. Everything lines up perfectly. The only hitch is that if I count the timing chain pins from 12 to 12 I only get 14 pins, the exhaust mark being at the first pin, intake at the 14th. No matter what I do it appears to be way off somewhere if I go with the 15 pin count. Everything is brand new so it's not a wear issue. Any help will be appreciated. Thanks, Greg.
