im guessing doing upjet is if you having a new exhaust upgrade or air filter performance

Stock machine = Upjet it anyway (the rear is a little cooler as fuel has a cooling effect) & should run a little better in 5th.

Modded machine -> K&N Air Filter  or  Stainless Exhaust pipe or End CAN = upjetting mandatory ofcourse.  Modded bike ? = Baffle runs better with baffle in than without baffle on any 4T (& quieter anyway! 😉 )

Laser or IX plugs help a lot.   If the plugs are “coffee brown”  the bike is happy!

The stock ones are too sooty & a nightmare for UK winters, usually chuck em first thing lol.
