    Hi all,
    I have bought a very nice SR125 99 model its been sitting for many years in a showroom so scooter is mint but im guessing seals are going to be dry so im doing a rebuild.
    I have a few questions if anyone can help. I have ordered a Malossi 172 kit, new crank seals, new belts etc.
    The kit suggests just raising the carb needle to the highest slot ?! But I guess up jetting would help it further.
    The SR125 has 82 main jet as standard I think but what would someone suggest with the 172 kit and standard exhaust.
    Thanks Edge

    I'd use a 90-92 main.
