Bigger main jets upgrade size for gt125r 2015

[Josh D]

I have ordered an after market exhaust end can, and just need help finding what size main jets should i get.

I am thinking i would need front:90 rear:92.5 main jets. mine has the stock ones which are front:87.5 and rear:90.

Yes you are correct for the 125 it is 90 front and 92.5 rear as an upgrade.👍
