[@wingding028]

when i done the exhaust i took the whole wee pipe out of the silencer the bit with the 4 screws in it it opened it up a lot that was on a 05 wr450f waiting mo my 2018 wr450f coming

How about the gas throttle? The 7th generation of the wr450f got it, you can't use full throttle, only half way. The 6th generation is not blocked?

What lift strap is that? Did you have to make modifications to make it fit?

[@allanjamesferguson5168]

Do I have to get the ecu 1st or can I do the mods and than the ecu

[@renedelafuente123]

With my luck the rivet I would be drilling out would probably fall inside the exhaust pipe, then how the fuck to get it out? Anyway I have a 2012 wr450f dirtbike and would love to do all those mods but not a hands on guy or I should say not mechanically inclined. I could probably due the air filter and exhaust modification. But my hats off to you if you did all of them. Thanks for sharing, like the video.

Wouldnt it be running lean with the intake plug taken out or does the new ECU fix that

[@Creeper-m9]

Fuel injection should adjust for it as far as I know

[@donbrashsux]

Did you win..

Hi, i bought 2016 wr450f and i think derestricting mods are done but when I connect power tuner throttle opening goes to 79 units max... does it need to go to 100 or this is like it should be? What about yours? Thanks😉

[@Creeper-m9]

Was the throttle stop screw changed? I’d imagine so since the stock one limits you to 1/4 throttle
