YPVS TONE Posted October 18, 2013 Share Posted October 18, 2013 bugger!...I'm not familiar with how to set up that pump Hi Airhead & dtluke Just had a look at a copy of the Haynes which has a section on the 1997- on DT125R's and it say's to set the pump to open the throttle fully and hold in this position. At this position the line scribed on the end of the oil hose union (which you can just see on dtliuke's photo) should align with the reference mark on the pulley. If not adjust the pump cable until the marks line up on full throttle.The picture in the Haynes isn't very clear but it looks like with the marks aligned this puts the cable nipple in the pulley at the 6 o'clock position and the 4FL stamped on the pulley at the 3 o'clock positon. Hope this makes sense. Tony Link to comment Share on other sites More sharing options...

YPVS TONE Posted October 18, 2013 Share Posted October 18, 2013 Update I've got a copy of the DT125RE 2005 Yamaha manual and it say's "The adjusting marks a and b has to match when the throttle cable free play ends" The mark "a" is the scribed line on the end of the oil hose union and the mark "b" is the "O" line on the pulley. Looking at your photo the two marks are nearly lined up maybe a bit over on the pulley so when you remove the freeplay from the throttle the two marks should line up. Just another thought if it's getting through a lot of two stroke oil it maybe leaking through the oil pump seal in the RH case into the gearbox oil. Can you check to see if the gearbox oil has risen ? Tony Link to comment Share on other sites More sharing options...

Its just a bit fiddly to get it right Roughly 4 tanks of fuel to 1 ltr of oil,,,, sounds about right Link to comment Share on other sites More sharing options...
