Everything original except for the bore, probably not much difference in jetting. Filter to carbs is clean....
If it runned OK before bigger bore, same settings must work. 1 step up to see if you get more torque at lower rpms when twisting the throttle
Different flow such 4-1, ported head + cam etc need more air and fuel
You will see when driving....
Full speed and bike will go faster when reduce throttle just a little..... too lean mains.
