Not sure if i need new jets or not....

Hello everyone,
I currently have a 4 into 1 exhaust, pod filters, and I am in the process of putting in some Wiesco domed pistons (same displacement but compression goes up to 10.25/1).

Will I need to rejet? If so, how much bigger/smaller should i go?

The bike was running well with the exhaust/intake with 122.5 jets.

The AFR will be the same, regardless of the compression ratio. So, unless the jetting was faulty before you will not need to rejet after the changes.
