    Hi all.
    So I have an Aprilia SR125 with Malossi 172 kit and dellorto 25mm carb.
    I have been setting the carb up by ear and how it rides plus plug colour.
    So I have settled on 50 idle jet 106 Main Jet and Needle on top clip. All seems good
    apart from if cruising say at 55mph open throttle and it bogs then goes. If I go any bigger
    on the jets it wont rev out in top any smaller plug looks to light?
    Any suggestions would be great.
