I've got an '06 450 and having real issues installing the cams and timing chain. I am not quite sure the front chain guide is completely installed. I pushed the upper locater on the front timing chain guide after I got the head torqued down in the small notch between the cylinder head and the cylinder, and checked with a flashight. After I pushed it back in as far as I could the top of the guide still contacted the exhaust cam with the chain out of the way and the cam fully seated. Should I loosen the head bolts and see if I can push the guide into the upper slot any further, or is that the correct position for it to be in? With the cam fully seated, how far do you think the top of the front chain guide should be from the teeth on the exhaust cam? Also when you put the cams in, do you put one cam in first instead of the other? Do you put the caps on the cams and put the bolts in at all, or do you put the chain over the cams and then seat the cams? Any help would be great.
