Thats really cool man. One thing i would love to see though, is a YZ450F silencer fabbed up to fit, that would be rad.

Instead of having to cut the splines yourself why not just get a blank sprocket then space it out and weld a standard one with the splines cut out to it. I believe this is how mine was made.[/b]

because mu design wouldnt alter the shaft persay, it would still allow you to change sprockets on the fly, which is what im looking for.

not at all Kyle lol. I mean like the end silencer, not the header. They look badass and sound awesome

The best I can say is let me get mine back and make sure everything works like of should and then I will ask him if he would do another one and how much he would charge, sound fair? Although if he is too busy I will send you all the plans I have so you just have to copy them down an take them to a shop and be like here do this :)

Hi, Ive been following this thread and just wanted to know if the same swap would pertain to the yz426 motor? Or is it completely differnt from both 450 motors?

I have an 04 yfz450 which grenaded the motor also. I can buy a yz426 complete bike for 800. would this swap be the same as far as the mounts?

I meant are the mounts on the yz 450f the same as the yz 426? I know you have to change the yfz450 mounts.

yamaha4life127 · 07-28-2009, 06:48 PM

i couldnt tell you 100% but i think they are. either way he swapped the 426 and i swapped the 450 and we both had to alter the same points on the frame, i dont know if we had to alter them the same amount or not though

yfz_guru · 08-04-2009, 07:22 PM

just curious to see how your project faired out

yfzracer10 · 10-17-2009, 02:07 AM

Look at the oil line going to your head on your 08 and try to find the same oil line on an 07-08 yz450.

yfzracer10 · 10-21-2009, 12:29 AM

what oil line??..if the cylinders are the same the head will work.. so u just have to bend the front motor mounts and add spacers on them
