Yea it was its got a 182 main jet now, runs way better now

[@MonsieurMoteur]

amazing look!

[@pastorjdh]

The purple and blue pipe is showing the bike is majorly lean. You probably already know that though. I got the same pipe on an 08 and it is awesome. I am jetting now and about to order a 180 for the main. Stock is 178 and just a tad off.

[@shewantreloadz3283]

Holy shit that pipe is dope

[@loojzo]

hello i got yzf 250 2011 with yoshimura rs4 stainless steel full system exhaust, can you please said me which jets you got in carburetor ? which jets u use ?

[@grahamkijowski8339]

Where did you get your graphic kit?

[@RideQc]

To jet a carb with a new exhaust you only have to change the main jet??? Because a lot of guys in the comments are like ohh I but a 180 main jet but I don't see guys talking of other stuff

[@kew168yamaha]

$730 it's the carbon/titanium full exhaust

[@hectorflores4390]

what where your jetting specs for this exhaust system on this bike...

[@hectorflores4390]

in videos they sound the same compared to in person.. i was just wondering if it did wat about performance how is it? thinking of getting this pipe for my 13 yz250f

[@kew168yamaha]

yea changed the bike completely a lot more snappy, would deff recommend a power bowl. right before I sold it it was bogging out here and there and the power bowl fixed that

Sooocolorful he's on Instagram, shift&twist

[@kadenshoemaker9947]

What jetting did you use for this setup? I have the same year yz250f and i was wondering because I wanted to get the same setup

[@kew168yamaha]

kaden shoemaker in the other video comments it should say some where what they are

[@harryscott8818]

if u dont mind me asking how much was the rs4

[@hectorflores4390]

what were your best jetting specs?

[@liamferguson7]

arn't the 2012's fuel injected?. pretty sure i saw a carb there.

[@kew168yamaha]

2012 are still have carbs the 2014 was the first year of fuel injection

[@adriannegron6974]

I have a 2012 yz450f with fuel injection header does a circle under the seat and motor is reversed in the frame

[@adriannegron6974]

But maybe they didn’t do it for the 250f

[@kew168yamaha]

Adrian Negron this is correct

[@adriannegron6974]

Kevin Wilson nice bike bro 👍🏻

He's on Instagram, shift&twist

[@hectorflores4390]

does it sound better than the stock pipe?

[@kew168yamaha]

of course it does, look up videos of the stock 2012 250fs. at least I thought it sounded better

[@Devo_ape]

What's his new Instagram name. Shift&twist is not it anymore
