Maybe I'm not paranoid and "they" ARE out to get me too!!!
Na, they would have gone pretty far out of their way to do that! My front brake caliper was loose after a few hundred miles! |

Jim, I like those bearings on my stem as much as the next guy, but that isn't the biggest problem here. She's getting pogo-ing and (dependig on the op's answer) excessive sag. That sounds like fork internals, not head stem bearings. Those are for AFTER we get the pogo feeling figured out.

and here i thought stem bearings were responsible for controlling fork damping.

My first suggestion is to check for metallic noises/sensations while topping out the forks, which could be internals or the commonly loose and failure prone bearings. Not every rider is a great diagnostics tool! |

Its a brand new bike. 1200 ish km on it (booked in for first service early next week)
it sags about 40mm-45mm with her weight and no preload spacers. its in the right ballpark when I added the spacers. |

I'm getting 25mm of bike sag at the fork, full gas tank and a tank bag loaded with 3-4 lbs., 9,000 miles on stock springs and stock length preload total. I cut the spacers to allow for the emulator length. You had 30mm on a stock bike? Not really that far off considering the tolerances everywhere else!
How experienced and mechanical is the rider having the problem? What is rider weight? |

The information in this thread is weird. I always thought that compressed air/gas injection into an oil based shock was done to pressurize the oil chamber and prevent cavitation. Only small, small amounts of air should be added and the actual damping is still done by the oil.

OP was looking for more spring rate/bottoming resistance, not damping from air.

70s era dirt bikes used air, oil, and springs. In the 80s the shrader valve on dirt bikes was there to release air after the heat of the fork movement increased psi and resulted in a harsher ride. Now some mx bikes 450 Honda and kawi use air as the spring rather than a coil spring.
