Advice for cutting down rear fender.
« on: February 05, 2010, 07:46:03 PM »
I want to shorten my rear fender on my 550K by cutting at the front and then shifting it forward so I can keep the finished rear edge nice. i would like to remove and remount the mounting bracket on the fender to make it easier to remount it on the bike. The bracket looks like it is attached to the fender using plug weld i am guessing. Has anyone ever tried to do this? I thought of trying to drill out the plug welds and then reweld it in the new location but there appears to be many of them and I'm not sure if it would even be effective in releasing the bracket from the fender. Plus, I am worried that if I tried re-welding it to the fender, even from the underside, that it would damage the chrome finish on the fender from the heat. Most likely it would just be easier to make some custom mounting bracket once the fender is cut. Any ides or thoughts would be very helpful.

If You can't fix it with a hammer, You've got an electrical problem.

I took some flat stock, bent it. I welded mine, but painted my fender. You could probably drill and bolt it. Works great.



Here is the upper mount. On the original fender it is raised. When you trim and rotate it forward you will need to compensate for the gap. I got some steel spacers, trimmed them, and angled to fit.

thats it, exactly what i wanted to do. i was hoping to figure out a way to reuse the stock mount but can't figure out how. I want to keep the chroming on my fender so I want to try to figure the best way to do this with the least potential for damaging it. Thanks for the pictures.
