That is interesting. Yes, I will install the other used fork when it shows up. Front Motor mount and bell housing mounts are all new and I even pulled the bell housing mounts out to look at them- they are fine. The cast clutch forks in the trucks have been hard for me to find. A while back, there were still some NOS ones…I should have jumped on that when I had the chance. The pivot ball is new, and my clutch fork fits on it nicely and operates smoothly without any play…but the fork cup it might be ovaled-out off to one side a sit- I can’t see it or feel it though.
I will just swap the forks and see if it improves. The geometry of the linkage: Pedal-rod-fork is not ideal- the rod pulls on the fork at a slight angle (the rod with the hook in it is not parallel to the motion of the fork when it is installed). At this point I am looking at everything… so far, I cannot see anything bent or adjusted improperly.
Thanks Jerry!
