2 Wheels Posted September 13, 2011 Share Posted September 13, 2011 You will need the manual for the bike. Different bikes have different order's,,,,,,eg. start at piston number X Drop the oil, take off crankcase cover,,, prob be markes stamped on it to align TDC,,,,rotate with a spanner its usually intake valve first,,,,,always dont on compression stroke. Not an easy job if you've never seen it done before. If in dout have a garage do it for ya ! Best of luck. Welcome to the YOC Link to comment Share on other sites More sharing options...

YPVS TONE Posted September 14, 2011 Share Posted September 14, 2011 Seem to remember the early SR125 had two inspection plugs you undone with a large flat screwdriver on the LH crankcase cover so you didn,t have to remove the whole cover. Not sure if the later ones were the same. You should then be able to turn the engine over with a socket while looking for the TDC mark. As 2Wheels has said the valve clearances must be done at TDC on the compression stroke with both valves closed. Link to comment Share on other sites More sharing options...
