    Hi guys I have a superbyke rbp 125 .
    Iv put on a 26mm MIKUNI VM22 .
    See the prob is this bike just don't have any thing left in it once you get to 5th gear . Iv also got a 17t sprocket on the front the jets as standard are 95 main and 15 pilot . I know these ain't gonna be super fast I understand that but 50 mph flat out on a 125 is bad lol . And before all the get a bigger bike bla bla bla no ! Stop ! Lol
    This is the bike I have and I have to deal with it hahahaha .
    So my question is ..... What's the best size jets to have ?? And will a sponge pit bike type air filter be better then the airbox ? And should i change the rear sproket ? .. Like I said it ain't the best bike (far from it) but I would just like to get it running to its best :-) thanks

    RBP is a mid 00's chonda. Most stock carb in chonda is based on Kiehin.
