kz650 swing arm question

I have a 79 kz650 and I was wondering is there a swing arm that bolts on and will allow a tire bigger than a 130? Also will the stock rim fit a tire that is bigger

Run a search in the arcives for swing arm convertions ,, The Suzuki GS1100E is the most popular But many others have been made to work also , Look in Projects too as I have one on Cafe Shoe , Good luck with yours
