2020 YZ450FX Gets A FMF 4.1 Slip-on 

Bike sounds nice with the new exhaust. Hayden with the hat on that honda tho... That shit was too funny! 🤣

93MPH and it wasn't done. That thing is savage!! I wasn't expecting that at all

That Mexican on his trike LMAO

Metigulous, isn't that a youtube channel that hasn't posted in about a month?

About time to see some bikes outta you guys! Love it!

missed that “yall want some fockinnnn cheese burgers” intro ngl 😂

You are insane going that fast on those tires. So freakin sick🤘🔥🇺🇸

everyone who every puts go pro on helmet: points at ground

Good wheelie good news on a possible new shop and a good choice to feed the dad bods it's all good little bro PEACE!!!

You and Hayden sharing a shop to funny can't wait for the content. Have a good day and stay safe Jimmy from Massachusetts

Yo who was that Mexican holding the water...🤣happy birthday man .love the bike more vids man

Can’t wait to see 17” wheels on that bad boy

Wyatt been missing you and metigulous.

The Yamaha is crazy! It don't look so crazy on camera but I know those is awesome rides. Always looks slower than they are on camera but it's crazy fast irl. WOW hope that the possible new shop comes together for you and Hayden! You guys always seems to be haveing fun. And hopefully Hayden starts his own company with makeing cages and exhaust manifolds and other metall work on vehicals. He's too talant not to be doing it. And it's just more fun to share a shop together and you guys can motivate each other with the jobs. Also maybe more RU-vid material can be done from both of you to that way. Shoutout from Sweden and stay safe guys!

Great Video, Awesome Garage!

I love the FMF

That was awesome hell yeah

Finish the damn truck

About time one of you made a video.

Happy late bday and sick bike bro

Are you gonna follow the tight valve adjustment schedule. Curious to see if it truly needs that tight of a maintenance schedule

Happy birthday bro oldman 😁

You should try the rich coupler if you did a full system fmf so your not running lean

impressed me with that wheelie next bike im looking at buying

With you going down in teeth on your motard remember you are dropping overall tyre/rim size as well. So it probably won’t be to far off what you have now. My motard set up I dropped 9 rear and went up 1 in the front and that was pretty close to my dirt setup.

Nice wheelie

Hell yeah!

Did you put some gasket maker on the header? I bought a pro curcuit t6 slip on and did the same thing because the gasket maker never dried correctly and there was no place to bolt the heat guard on....

Damn man loved the video what's the specs on your shop you got it set up so nice would love to have that on my property

That was a a nice wheel popper u did there

You ride a wheelie pretty good!

Yo new shop bigger and better would be tight..more uploads to then 😎😎😎🤟

Were did the jeep go?

What happen to old shop?

gotta adjust gopro mount to point higher up. supermoto bike is gonna be sketchy and awesome.

Did you have to remap

What happened to the shop Hayden was getting into the that guy I cant remember his name but yeah what happened to that

Torque monster

My banshee also tops out at 93 mph.

Gotta post more do enjoy the content

Hell yea daul shop diesel gas motos wheelies 🤘🤘🤘🤘🤘🤘

Special visit from Phil..... Phil Mycrakin!

Believe it or not but I had a Suzuki DR100 on/off road dirt bike was I was a teenager and everyone used to race on the highway close to my house so I took my lil dirt bike and raced it and clocked it doing 95mph more than once

Sketchy!!

Hell yeah bud get the cam tilted up everyone always keeps their head down while riding or mount it on the back and get some crazy rooster tails

With the new exhaust, do you have to increase jetting?

Need to put the gopro on the chin piece.. top of the helmet gives a view right in front of the bike..

Sounds exactly the same to me

Can't wait to see it become a moto???

Sucks you guys have emissions control that’s gotta blow for a lot of stuff there. And how tall are you because I’ve seen 450s and they seem really large

Y'all wild. New shop would be sweet. Just put another building on the PFI land. Except then you'd never get anything done. Too many distractions. 😂

👍🏻

Very slit difference.10 point cage $

Well you have a couple of episodes of the supermoto build, time to drop this one half way and move on to something completely different....

Amazingly long gear ratio for a bike with off-road set up

Exhaust sounds the same on camera.

It’s a 6 speed buddy. You got another gear!

😎🇺🇸🥩🍺

i dislike how the fmf hangs out further than the stock one !!

Swear to god if y’all get a shop in Berthoud, I’m gonna bring y’all some fucking cheeseburgers.

Hit imi with me and curt 🤘

Tell hayden to post more vids

Hayden give up on RU-vid?

I can't really hear the difference lol

First

Last thing we wanna see when you have started hole other project bud is slip ons

Next time aim the camera up a little higher

Chin mount go pro has way better POV

Defo needs a helmet on that 3wheeler ,any bike for that matter,did you have a helmet on the 450.?? Hope so otherwise you will fuck up one day bro and will end up in a wheelchair or worse!!!

Did Hayden lose weight or is that hat is just ridiculous...... ;)

Truck truck where's the truck...no one cares about bikes ;)

Vw tdi swap your jeep!

You stopped saying ‘sup fuckers’ and it’s ruining my life
