I have different packing? Its more of a stringy packing..Is this okay?

[HMFengineering]

@MegaWassup12345 We recommend using genuine HMF packing as it is a predetermined density and a special blend of materials.

I was wonderin...is there a pipe for a ktm sxf250 im looking forwad to hmf!

[HMFengineering]

@HondaRiderPR14 Check our website HMFracing. Go under the "Dirt" section, then under KTM. We have a 250 SX-F model, 04-09. Should work if that's what you have.

Is there any way to get a replacement core for an HMF pipe? I have the sport series for a LT-Z, and the core broke.

@hammerheadZ1 you're correct, you don't need the quiet core. That's sort of the beauty of it. It can easily be removed or added, depending on where you're riding. That's why the Competition Series is a little better because it comes with 3 inserts that work like the Quiet Core.

[hammerheadZ1]

@HMFengineering yes

[HMFengineering]

@hammerheadZ1 Are you referring to the Quiet Core?

[HMFengineering]

@MiddleRiverMudders It depends on how often and how hard you ride your machine. 30-45 hours is a good time range to repack the pipe. If you aren't too hard on your machine, you can stretch it. One way to see if you need a repack, knock on the can and listen for hollow spots. If you find a lot of hollow spots it's time to repack.
