TOPIC:

I'm considering taking a different route with the swingarm mods for my Z1 project. I currently have a GS1100E swingarm mounted with shims. I also have a rear wheel from a ZX6E.
Due to lack of funds, I'm thinking about going with a swingarm from a 1982 GPZ1100 (which I already have, along with a rear wheel). My current dilemma is that the GPZ swingarm is about 1mm wider than the opening on the Z1 frame. My question to you fabricators is how do you suggest I trim the gpz arm; ie. what tool is recommended? Another thing to consider is the spacers that the pivot bolt rides in that the needle bearings contact. Those 2 pieces are obvioulsy hardened steel. How would I go about cutting them?
There will be other questions, but many thanks for your response to this one.

Here is my 2 cents. On the GPZ1100 swingarm you are still dealing with small round tubing which is not very rigid. The GS1100E swingarm is boxed aluminum, much stronger and resists bending under load. If it was mine I would use the GS.
