I am attempting to upgrade my wattage out-put on my '98 Wr400. I bought a take-off from BajaDesigns (probably paid WAY too much. $180.00 for the stator off of a '00 WR) and I pulled the left-side cover last night, and I don't have sepcial tool #Yam-Piece-'O-Crud_rotorstopper. Will a strap wrench work? I tried putting it in gear, and standing on the rear brake, but the rotor kept turning. Any input will be greatly appreciated. Gracias!
