burton500 Posted January 30, 2012 Share Posted January 30, 2012 Hi, need a bit of advice about the square junction box on the throttle cable. Where the oil pump cable and the carb cable meet, there is a white round plastic housing. Is that round housing supposed to be able to rotate? My one gradually gets pulled in one direction, so that eventually the bike won’t tick over below 2500rpm, because the cable is being pulled tighter. The Haynes manual doesn’t appear to help, so wonder if anyone here has had this happen. Cheers Lee Link to comment Share on other sites More sharing options...
YPVS TONE Posted January 31, 2012 Share Posted January 31, 2012 I think you will find the round housing with the oil pump and throttle cable around it is as you say supposed to rotate. I remember looking at the one on the DT125MX I had and it looks like as you open the throttle the round part in the middle rotates to take up the slack in the two cables then locks in position by small " Teeth" around the outside". Are both bottom oil pump and throttle cables free and not seized ? I seem to remember you can disconnect both cables from the junction box to see if they're free. It mentions the junction box in the Haynes manual for the DT125R and says NOT to lube with grease or oil but to use WD40. Tony Link to comment Share on other sites More sharing options...
