Posted May 19, 201212 yr Hi! I have TDR 125 2000 and I want to derestrict it. I know for the exaust and inlet manifold restrictions but there is an one electric restriction which retarts revs when they reach 8k. I heard that there is one wire which needs to be grounded, but I can't find it. Can anyone please help! Thanks!
May 19, 201212 yr Just found a Yamaha Service Bulletin ref TDR125 Engine Power Modification which mentions about turning the powervalve anti-clockwise until the dot aligns with the lower edge of the allen bolts and also removing the Black/Blue open ended wire from main wiring harness and to fit a ring terminal to black/blue wire and earth to regulator/rectifier mounting bolt. Hope this helps. Tony
May 20, 201212 yr Author I will try this thing with power valve tommorow. Can I found that wire, without removing the fuel tank, because yesterday i filled it up to the end, so or I need to spend, all fule(which isn't big problem) or is there another way? Thaks, a lot!
May 21, 201212 yr The picture in the bulletin looks like it is under the tank. It looks like the Black/Blue wire is in the wires from the CDI unit just behind the block connector on the wiring harness side. Tony
