I welded mine up with a cheap nasty gasless mig.
Over built the material and then ground it back, came up looking good and works great.
Hardest part was getting to the sidestand, I stuffed my exhaust nut in the process.
When removing the left exhaust pipe to gain acccess, if the flange nut doesn't free up within a 1/4 turn STOP what you are doing. It will need to hacksawed off or it could cost $$$. anti-seize when refitting the flange nut. Wish I knew this BEFORE I did it.
