Yessir I appreciate it. Its one of those Rapp weenie pipes I believe. I can keep up a fare bit of momentum so Im gonna bump my gearing couple teeth and see how it pulls @6000The BSP sealed motor has a weenie pipe. The RPM on a momentum track is about 6000-6200, if lifting maybe 6400.
The motor on a dyno will go higher, but power loss is major at the higher RPMs.
