im doing a k1 tail conversion at the min and its really simple. the only down fall is the fact the subframe is ally so if youve not got an ally welder u need to find someone to do it for you. its pritty straight forward once youve sourced all the parts.
all depends wether you want to carry passangers or not. if you dont then go for a race fairing
thats if you havent definatly decided to keep the srad back end
