So I've been dealing with my car tossing a rod recently and haven't had time for the bike.
I got all that straightened out and it's bike time again.
I did some mild porting and slapped the head back on tonight. I was trying to set the chain and I kept running into a slight amount of error.
First off I didn't pull the stator cover so I can't see the "T" as my worthless Clymer's manual states. Instead, while the head was off, I rotated the piston until I saw it at the top and the scribe on the stator pulley lined up with the notch in the stator cover.
I jiggled the cam gear around until I got it close but it seems like it's perpetually one tooth off.
I know, by my own eye, that the piston is at TDC when the line on the stator pulley is at the top to middle of the stator cover notch.
When that occurs the cam pulley has a slight angle to it.
If I move the crank so that the notch on the stator pulley (purple) is just beyond the notch on the stator cover and the piston has already started it's down stroke...
then the cam evens itself out...
I can write this off as cam chain stretch. I justify it in my head because it was already rattling in the danger zone (I've since gotten my Verslagen-ified tensioner) I just don't want to make a costly mistake now that I'm this close to riding again... as the season comes to an end.
I did try jogging the gear one tooth forward and one tooth backwards from the position I am at now but it only seems to get worse. This seems to be the closest I can get it.
Questions, comments, suggestions, concerns? Put my mind at ease, please!
