hmmm dunno about a before and an after price... you might have picked it up for next to niks... $50. or possibly been ripped through the @rse hole and payed $1500.. dunno...
As far as looks wise go, all i can tell that is different is you have repainted the number plates in white, added the 86, put new honda flags on with the 80 stickers, and maybe given her a wash!??
maybe 25$ more than what you payed for it.....that would cover spray paint, stickers and water used to wash the bike..
recover the seat, freshen up the rear swingarm, strip down the frame, repaint, rebuild the donk, clean up expansion chamber and exhaust sys. rebuild front n rear susp. rebuild the gearbox, new rubber, new bars and grips, new brakes, new chain and sprockets.. Only then would it be really worth trying to throw an estimated $ sign at..
swap ya 4 an AGB 125. lmao.
just my thoughts, but looks like its in good condition for its age...
