[@grudzien9784]

I have the same bike, gonna get a shorty. Need to get a expansion chamber too. Looks sick

[@masontodd516]

Thanks man! Yeah get it done!

[@cmnatal11]

Nice vid! Would be nice if you make another video talking about the diferences and what gains did you get with the change.

[@alexamg6675]

Looks better sounds the same

[@brainstain22]

Nice man...hopin my dealer can find me a 125 come july.

[@masontodd516]

Heck yeah! They are hard to come by right now

[@Music-pq8cm]

Looks better but similar sound … maybe even a little bit quieter?

[@MountainStorz]

What jetting are you running? Elevation? Mix ratio?

[@DantePrevost-nc6tu]

Where did you get that pipe from

[@masontodd516]

From FMF directly

[@JohnDoeEagle1]

Cool bike and custom pipe. Pat yourself on the back for buying a REAL 2-stroke motocross dirt bike instead of what the EPA and tree huggers are pushing in 4-strokes these days. They are practically forcing people to buy and ride them now. 2-strokes are faster CC vs CC displacement, shootout of the hole better and are much cheaper and easier to fix along the way. Once a 4-stroke needs a rebuild or top end kit you might as well scrap it because it is junk and will cost more than it is worth and take a certified mechanic to repair! Keep the 2-strokes off road on the dirt and the 4-stroke on the street where they belong.

[@masontodd516]

BOOM! I agree, two strokes are so much fun on the track and trails. Nothing like that two stroke power

[@lucashysert6775]

You said it best!

[@devinwillis7787]

2 strokes are more fun but the 4 strokes are way faster

[@JohnDoeEagle1]

@@devinwillis7787 That is what the EPA wants you to think. Why do you think 250cc 2-strokes race against 450cc and 500cc 4-strokes.

[@JohnDoeEagle1]

@@devinwillis7787 See how slow and "sluggish" this YZ450F is? Who cares about top speed wide open on the straightaways. Off road and on the dirt that isn't the kind of power you are using anyway until you want to kill yourself. Now look at these YZ125s and see how much "faster" they are with a much much smaller engine. kzbin.info/www/bejne/epmUiKiBrsijo5I

Ride it...

[@masontodd516]

Tomorrow!

[@tylers2983]

you should really re jet it

[@masontodd516]

I still haven’t rode it yet lol but I think I will on Monday and see how everything feels

[@AJC-jo3ds]

Mine came super rich new from the factory, had to reject the pilot jet way down to 52. It comes with 72 which is crazy.

[@nicktobin2840]

I’m at 55 pilot and 170 main, it’s wayyy too rich from factory

[@GeorgeWashingtonknows]

Sounds the same barely a difference.

[@sariamubarak9804]

Yamahas 2 strokes sound good from birth.

[@GeorgeWashingtonknows]

@@sariamubarak9804 I agree

[@masontodd516]

I agree, but it looks a whole lot better and rides amazing!

[@cmnatal11]

Nice vid! Wold be nice if you make another video talking about the diferences and what gains did you get with the change.
