Just gota 96 vulcan classic and it needs a little tlc, first off are the sprockets and tires. (can see the threads on the tires). only paid 400 dollars for this bike, the owner had just got a new one and just didnt want to worry bout fixing up his old one. anyways i just wanted to know the largest rear tire i can put on with factory sprockets, and if i wanted to go to an even fatter rear tire, whats a good company i can go to to look for sprockets that can fit a larger tire. any help is welcome.

 

was a little confused at first the sprockets arent what i was looking for as far as getting a fat tire kit, but rather what company should i look into to get a custom end to fit a fat tire?
