2016 Yamaha WR450 headpipe removal ?

Recommended Posts

Having problems removing the front half of the headpipe on my 2016 WR450. Can anyone give me any tips? I have it all unbolted it will not fit to remove? Do I need to remove starter heat shield / and / or other parts?

Thanks Steve, You were right it comes off right side with a little pressure. Went back in a bit harder after wrap.

Thanks again

Thank again snake. I guess we will find out on this one. My main concern is engine heat and heating the fuel above with the Wrap around pipe design. If it saves my motor I am ok with sacrificing a pipe. Having said that those pipes get glowing hot where they come out of the cylinder. . I cant imagine a wrap causing any more stress. Have you heard what happens, does the metal crack?

If I'm not mistaken it disintegrates the pipe after time. 

Ive run my fully built 16' big bore with GYTR head up the biggest hills without overheating. The only time to worry about the motor overheating is if you somehow lose your coolant and run the motor without it. 

On my built 07' I run a sticky insulator sheet under the fuel tank.

Throttle Violence; I now have 135 hours on the bike. The wrap is pretty beat and I should probably replace it but I would do it again. It did what I thought which is keep heat out of engine compartment and boiling gas. I see no signs of pipe deterioration under sections where wrap is wearing out. I run Zip Tie racing non boiling coolant and have a tusk thermometer radiator cap. Bike gets hot in long mountain climbs (running GYTR pipe tip and ECU set at zeros). Usually runs under 200 now and then 225 if torturing it. This last weekend at 9,000' climbing 5,000 ' straight up for 10 plus minutes at the top it was 275 degrees and fan running but ran perfect and no coolant loss. I just had valves checked at 130 hours and all were perfect. Love this bike except it is heavy. Throttle on buddy.
