Jetting is often dependant on several factors, one of which is how much piston gap you have. With a larger gap it sometimes helps to use a bigger main jet allowing the increased gas/oil mixture to better fill the "gap", thereby increasing compression.
This means you can lower the needle setting to get the same low RPM torque from the bottom and middle range.
Sometimes works.
We often run main jets in the 162-165 range when the temp is around 30 Celsius. Don't see that as a problem.
