After having my frame and swing arm powder coated and fitting new pivot bushes I find out it is bent in the lateral plane.
With the arm fitted the suspension units are out of line by about 9mm top to bottom (bottom out towards the left). With the wheel mounted using standard spacers it is offset to the left also by about 9mm.
If I space the wheel over to the right by 9mm, the wheel is central, aligned correctly with the front and the chain line is correct.
I guess I need a new swing arm but MX4s are rare. My MCS/2 arm is substantially similar in dimensions apart from shock mounts, are other arms suitable? Griffon maybe? it looks the same to a bloke riding galloping horse.
Any one have something suitable? Originality is not important to me
