Good job y’all ! Also loc tight is your friend!😂

[@Not.Nathan]

What size bars you got and hand protectors nice vid

[@imagine9375]

Sounds awesome!! Get some my boys...

[@Atomized.]

Should’ve gotten a full pro circuit t6 it makes them sound like race bikes

[@glockwhore]

Is this the spark arrestor version can you post the model number please

[@spidey3759]

can you make a video of a power comparison with the stock exhaust?

[@alexthreet5131]

i got a 2017 from a marine!!!!! LETS GO~~~~~~~~~~~~~~~~~~~~~~~~

[@crfrubicon]

Really enjoyed this video. I have one question tho, is this the Mini PowerCore 4 Slip on?

[@FoxRunAdventures]

Thanks, yes part number 041581

[@crfrubicon]

Ok. Thanks. Would you recommend buying an FMF Powercore 4 Mini slip on from Fortnine? And does the FMF Racing deliver that part number to Canada?

[@aljehannecasuyac9452]

How much diameter of the hole

[@cloud9ineclothing]

link for the exhaust?

[@remivancayseele8836]

hey a question on which website did you buy this exhaust

[@FoxRunAdventures]

I had to go directly through FMF because everyone was showing out of stock for like…months. It was the same price though and fast shipping. 👍🏻

[@abren8787]

I got a yoshi on mine !

[@emersonkoons1224]

How did you get it on the head pipe? I’m trying to install one right now on the same model and There is a welded piece at the end of the stock pipe that is the same diameter as the fmf pipe. Did you just force it on?

[@garywyckoff4864]

Hey so I can help with this, you don’t remove the mesh around the header, but you want to get it snug inside, I used a mallet and hit it into place

[@FoxRunAdventures]

It does appear to be welded at first but it’s a heat resistant mesh packing. We pried it up on one side with a flat head screwdriver, cut the mesh, wrapped the mesh around the new pipe, and then tapped it back on with a rubber mallet like Gary said.

[@youmoma556]

@@FoxRunAdventures so you cut the thick piece off and re fit it to the inside of the fmf slip on ?

[@youmoma556]

@@FoxRunAdventures currently trying to install mine ! Having a little trouble

[@FoxRunAdventures]

Yes, the diameter of the fmf is bigger than the stock muffler and won’t go on unless this mesh piece on the head pipe is removed. We cut the mesh, slipped the pipe on with a rubber mallet, and then wrapped the mesh back around the joint. The exhaust clamp secures the wrapped mesh.

[@hunterrichter4821]

hey, so will this void my warranty since it’s just a slip on?

[@FoxRunAdventures]

No, this will not void your warranty. 👍🏻

[@hunterrichter4821]

@@FoxRunAdventuresthank you for the fast response, also did you ever remap or did it adapt im assuming since it’s just a slip on there is no remap needed

[@FoxRunAdventures]

No remap was needed, fuel injection adapts quickly

[@tsanders23]

How tall is he? My son is big for an 8 year old and I am looking for him a bike.

[@FoxRunAdventures]

He was around 4’10” when we shot this video

[@wheeliedumb607]

Get a tune it'll run better

[@user-ie3yh6fw7t]

hey I have a 23 125fb would this fit?

[@itscliff2839]

Yea it will

[@jackwindham]

What protaper bars

[@funkymonkey12328]

Most likely the klx 110 protapers

[@alexthreet5131]

fuel injection has to be repamped??

[@FoxRunAdventures]

It takes a minute for it to adjust to the new exhaust with increased airflow. No remap.

[@jimmything1000]

Still running good with no remap? I read you needed it or it would run lean?

[@Braeden683]

Is that the mini

[@FoxRunAdventures]

It’s this one… HON CRF125F'19-22 P-CORE 4 MFLR 041581

[@JB-mo8rs]

Looks like the kid is just learning to ride; he doesn’t shift gears. Zero reason for a pipe at this point.

[@Imonursixx]

Clearly he's shifting ur just mad
