Race season is finally winding down, time to get back on bike projects! Trying to get my 74 frame jigged up to make it a hard tail. My question is does any body have good top down dimensions for these frames? If I plumb down fron steering neck and down from center of rear seat hoop and shock mounts (which is only measurement that i can find), both of the lower motor mounts and the rear axle center line are off about 3/8 of an inch. Also from outside of frame on right side is 3/4 of an inch closer to my centerline then it is from left side. Wondering what were the tolerences back in 74?? From what I can come up with is that my neck looks a little twisted in the chassis. Any ideas? Thanks, Dirty
