I'm doing up an RG250 and have run into a bit of trouble with modification. The bike came unregistered. I want to use a different rear end and seat for it as well as put on clip ons, new headlight etc. Now, I'm guessing I need to go about the 'approved persons' crap and get a modification for the seat and such? Would it be better to get the bike running, put all the stock things on it (the stock rear end etc), getting road worthy and rego etc. and then doing the rear end modification?.. I know that's not terribly legal but how likely am I to get a fine or something for it?
