found this web site. they state the 883->1200 conversion is only $295.00. they seem to do almost every type of machine work for almost any harley old or new.

Don't know about trusting that, seems the going rate is about 700.00 everywhere else. If it sounds to good to be true...

usually is. just figured i would post it so people could check it out. i don't know cost of doing certain jobs but some jobs did look a little cheap but like i said i don't know how much these type of mods cost so maybe some of them do cost what they charge for them. anyone looking to do these mods has most likely checked things out already so they would probably know what may be good or not. they have a lot more than just the 883->1200 conversion. click the link and they list a bunch of stuff with prices next to it.
