Rolling Thunder?

As a fun project, I decided to try to fine-tune my bike's power curve while keeping an ear out for change or improvement in the tone and timber.

With less than $2 in hardware, I put together an adjustable lollipop baffle, and now have a wide range of tunability:






For tight mountain rides, a 45 degree angle is ideal as the torque noticeably increases allowing fewer shifts with stout pull under steep but relatively short sections.

Turning the baffle to 180 degrees still creates some back pressure and improved torque, while allowing the engine to spool up quickly in longer sections of road and straightaways.

The sound is improved, a little lower tone over the rpm range and a little quieter, too. Still wakes the neighbors tho!
