I have read about using some of the other shocks on the blaster. I don't want to use the 400 shock becasue I don't want to cut the air box. I read that the 250r shock works but so far all I have checked seem to long. what length 250r shocks are guys using? Does anyone know the years that work becasue it seems to me like pre 86 and port 86 are both to long. Is there enough travle that I could install an internal spacer to get the length correct?
