DO IT YOURSELF - learn how.. why not? what do you have to lose.. it's simple, you remove the cover over the front sprocket, break the nut for the front sprocket loose, take of the rear tire, remove the chain with a chain beaker/press, take off the front sprocket, replace it, take off the rear one, replace it ( remember to use blue locktight on nuts) put rear tire back on, feed the chain, make sure you got the right lenth, take some links out of need be, connect the chain and tighted and adjust everything and your done, it takes me hour or less to do it, beginner, give yourself 2 hours, doens't matter how long it takes, it's your first time - PM ME FOR HELP, i believe you should have basic motorcycle skills, while chain and sprockets are above beginner by a notch i believe, because you do have to know what your doing with the chain tool and such, i also believe anyone can do it, it's simple once you know how, ask a friend who has done it before, or like i said feel free and PM me and i can help you
