micky Posted October 3, 2006 Share Posted October 3, 2006 Bet ya someone has posted something along these lines before, im new to this forum so i wouldn't know. Anyways ive had my DT 125 (2000 Model) for sometime now and am sick of the power, I have a full dep exhaust system and am workin on having my power valves adjusted but at the moment it tops out at over 75mph. I understand i wil need a new de-restricted C.D.I. unit and a set of carbon reed valves, but dont know where to start looking, what type i will need, or the different names of each type, can anyone help ?

Willenium Posted December 9, 2006 Share Posted December 9, 2006 Don't be letting people give you false impressions about the CDI. My 2001 model was incredible on stock electrics. Firstly, remove the seat and get the airbox snorkel off which will allow the engine to breathe better. The CF reeds don't do a lot so don't bother with those. Polish the YPVS and exhaust port. See if you can get an old toothbrush or something to scrub the top of the piston too as the more decoking you can do, the better the end result will be. The YPVS should have the valve sitting exactly flush with the top of the exhaust port when fully open. You can check this by putting your finger inside the port and adjust it by feel and check it by switching the ignition on and allowing the servo cycle to centre the valve.
