jimjam Posted February 4, 2006 Share Posted February 4, 2006 It doesn;t sound too bad. Leaky seal by the gear selector is common, easy fix. Tacho isn't too hard either. Check all the wires where htey connect into the clock. If not this then try another. Should be able to get some help for this from another friendly menmber. Leaky oil from Exhausts sounds like exhaust seals, again no major sweats here. Very common on 2 stroke engines. Link to comment Share on other sites More sharing options...
paulmould Posted February 6, 2006 Share Posted February 6, 2006 (edited) My DT 125R has the same leaky gear selector seal, but i recon the previous owner ran it without oil and i have a knocking in first gear, not too bad its gone in second, but does anyone know why it knocks ?? is it the bush or bearing that holds the gears on the gear box casing gone and its rubbing under the pressure of first gear.
