extended swingarm question

[DEMMYM]

He may be a good guy and the swap itself is cake but i'm thinking that 100 bucks doesnt include cramming up under that back end and grinding the frame out to clear the chain. If it isnt i'd just go pick it up and do it yourself or that chain will be done by the time you get home

Yeah you might want to ask him about the grinding of the frame, and if he says it doesnt need to be done. He would be wrong.
