I just picked up an old 88 Paul Turner Maximum Overdrive National Cylinder that is at 69mm, but there is a nice ding in the bottom of the sleeve by the transfer port. Looks like a wrist pin might have got into it. One of the intake bridge's are cracked at the top also.
Has anyone had a cylinder with this porting and would it be worth resleeving?
Do you know if anybody has used the round cr coil mount on an atc frame? I'm thinking the radiator mount tube on the atc frame would be the only place this might work?
