2009 Kawasaki KLX 250S: HMF

[sunsetsilvy]

that sounds great-how does that muffler differ in sound from the new competition series on the Klx250s? Which is louder?

[Theredhawk6625]

i have a klx250sf. will that pipe fit on my bike as well?

[HMFengineering]

@Theredhawk6625 Our exhaust does fit the SF model.

[Theredhawk6625]

@HMFengineering okay, and with a slip on exhaust, will my carb require a rejet kit?

[HMFengineering]

@Theredhawk6625 You're going to always want to retune your carb when you change exhaust systems.  Give us a call and we can set you up with the recommended jets

[TokenTombstone]

do you guys make a pipe that is quiet like the stock exhaust, but offers a performance boost? I can ride my stock bike anywhere because my neighbors can't hear it.

[HMFengineering]

@TokenTombstone Yes we do. If you pick up the Competition Series, you can use the Stage 1 insert to get the dB levels down and to keep a steady horse power gain. If you go out riding where sound isn't too much a of concern, pop in the Stage 2 or Stage 3 and you'll get a little louder, but a lot more power. It's a very versatile exhaust system

[justinyoface911]

i heard these burn out your tail light because of how high they sit. is this true?

[HMFengineering]

@justinyoface911 We had heat issues with our original system, but have redesigned it so this is no longer an issue.

[itube4521]

0-60mph in how many seconds?

[xGsDKING]

stock what is top speed

[akviper1991]

top speed??

[HMFengineering]

@akviper1991 We didn't test top speed. We do horsepower readings. Top speed can be affected by type of fuel, altitude, type of road, type of tires, gear ratio of sprockets, etc.

[HMFengineering]

We have not tested with an injected model yet. We have no info regarding tuning for these models. Thanks

[skybluestu]

Thanks, read online that it might need a 'boss' to accommodate the O2 sensor.

[skybluestu]

Hi, does this and the competition series also fit the fuel injection model that is sold in the UK and parts of Asia? Have emailed HMF directly but no response yet. Thanks

[HMFengineering]

I'm getting you an answer about that today sky.

[skybluestu]

Hello, any news on whether it would fit the fuel injection bike? Maybe a small hole drilled to accommodate the o2 sensor?

[JonnyXee]

@HMFengineering

Do you need to fit the 02 sensor or can you just hide it under the seat.

I run mine without it connected to the exhaust and it runs good.

[punkenduro]

good product i love mine. run the enduro end cap though, just think it looks better.

[HMFengineering]

oh yea, the euro cap looks way better!

[1tomarcher]

how do u get it to go 90mph because mine only dose 70mph

[gengiz]

for outright power the big gun cant be beaten when combined with a jetkit.

[HMFengineering]

We all have our opinion :)

[gengiz]

@HMFengineering not bagging yours mate probably great too but I have the big gun on mine 09 klx and mate has fmf on his mie made more power at wheel

[HMFengineering]

No worries man. The new Competition Series from us makes sick power. When we were testing, it made more power than any other exhaust. So it might be something to think about down the road.

[DISS42JR]

when you say it makes more power (im talkin atv's) did yall test dasa and sparks big core against it

[HMFengineering]

When we did testing, we compared the exhaust to FMF, Two Brothers, Yoshimura, and Leo Vince.

[Dragonfiregum]

Poor turn signal:(

[JazzEaglesDevils]

The pipe is going to melt the rear turn signal... Trust me, I know ;)

[teehee369]

what exhaust would u reccomend, i have a klx, looking to suit it up =[]

[Georgenfla]

Sounds really good man. What jet kit are you running in your carb?
