Does anyone know if its worth doing the derestriction modifications to the WR such as grey wire,Airbox and throttle screw..Have just ordered a FMF full system and JD jetting kit.

depends how you like your bikes to be the ally framed WRs are totally different with the mods done they have probably been done allready on an 07

My 05 WR450 has a full FMF Powercore 4 and powerbomb. Standard jetting with tps unplugged and grey wire intact. Seems ideal, no backfire on the overun and plenty of low down tractibilty. Still goes like stink and more than enough power for everything really

I have an early 2008 wr450. Was jetted and unplugged when I got it although grey wire still in tact. I have returned it to 'plugged' and std jetting - mainly to see if I could up my tank range - and the bike is now far better through the whole rev range and still goes like stink when needs be.
So I would say unless you are a racer that uses 101% of the bikes power to gain a place in a race then keep it as standard. Can only help with engine longevity too.
Either way if the bikes as described you will be mega happy with it. Love mine to bits.
