I have a 1981 kz650 and my buddy is going to cut and extend my swing arm for me. He has everything to do it except some solid stock tube(?) to go inside the swing arm tubing, I guess to give it more durability and strength I suppose.
So my question is.. Does anyone on here know the diameter of the inside of my swing arm. Im not sure how thick the walls are and I wanted to get the tubing before I went to him to get it done so we could just knock it out intead of bringing it over there, cutting it, then going to get tubing, then going back to weld it all together.
Thanks.
