Hi peeps,

Slowly getting there with my bike making it back into an enduro from Supermoto.

Got some WR400 Forks with new seals and 7w fork oil, standard 14-50 gearing from 15-45, Metzeler 6 Day Extremes, YZ front mudguard and a WR450 Rear shock (without the lower bearing! :smirk:)

The bike has spent its entire life in SuperMoto trim and the previous owner fitted it with STM slipper clutch, Auto Decomp Cam, K-Tech Lowered/Stiffened Forks, K-Tech Lowered Shock, 'Braking' Caliper with R1 Master Cylinder, Catch Tank, Gold Talon/Excel Rims with Michelin Pilot Slicks, Removed AirBox Lid, Akrapovic silencer.

I assume all the free mods have been done as it ran 52bhp at my local Dyno.

I just wondered how you tell the difference between the YZ Header and the standard WR as i hope with all the rest of the mods he has done, he has done this also.

I have heard its a bit lighter but is there anyway i can tell the difference as its the only exhaust i got with the bike.

Thanks again

Nick

Ps: does anyone know the size of the front disc bolts as im looking to getting another Magnetic bolt so i dont have to take it off my Wavy discs on my SM Rims. :smirk:
