Question about 2000 Yamaha DT 125 R
This method only works on pre1996 models,after that the restrictions became more involved than a washer tak welded into the exhaust port. after 1996 the bike is restricted in 3 main areas. 1.the exhaust now has 2 half moon shaped plates inside the expansion chamber(you will need to cut the front pipe open to remove these, then weld it shut) 2.the c.d.i is now set to ****** the power after 7k revs. source a pre1996 c.d.i. 3.the power valve, this is on a servo that controls its postion at a given point in the rev range,this is desinged to give a smooth power delivery and better fuel econemy. disconect pully cables from power valve rotate 180degrees lock into position,your power valve is now locked open. you will notice she sounds different,also a destinct lack of power until about6/7k revs. where she'll shoot off like a rocket as the power band kicks in. IF YOU ARE USING YOUR BIKE ON ROAD PLEASE DO NOT LOCK THE POWER VALVE. IT CAN BE A LOT OF FUN IN A FIELD SOMWHERE BUT YOU WONT BE LAUGHING WHEN THE BACK END SPINS UP ON A BUSY ROUNDABOUT. i do recomend re-jetting the main jet in the carb when de-restricting. go up 1 size i think i used a 260main jet. thats it, have fun but be carefull.
