I want to 172 my sr125 (A/C) , could anyone advise me where to buy the kit and any other bits I might need ? I need the bike to be 100% reliable but just that little bit faster , From what I understand I can just bolt the kit on , but will I need to adjust jets and the like ? Not very clued up on peds as not had it long , will be doing the engine mounts / silent blocks soon so whilst the engine is out I may aswel 172 it Thanks guys
The 172 barrel is a pretty straight forward fit , I would get a gear kit for it to stop it over revving. The std pipe works very well, just up jet carb to around 92 ish and try it, it may need slightly bigger. Remember start big the work down,
