free mods for 98wr = disconnect grey n sky blue wire, remove the air-box lid, shorten throttle stop, de-octopuss acv, yz timing n de-restrict ur exhaust.

the oni free mods for me is juz the grey n blue wires coz i've upgraded my carb to a yz426 carb. i've installed yz ex cam n a conversion to a yz450f bodyworks. u can also do a DIY powerNow called AvNow.. cheers!
