The oil pump settings for engine numbers AFTER 4L1-100101 (250) and 4L0-100101 (350) are as follows :
Open the throttle grip fully open and adjust oil pump cable until mark on the pump pulley aligns with the pump plunger pin.
If the identification mark on the pump pulley is '1M1' use the square mark for both 250 and 350.
If the identification mark is '4L1' use the round mark for the RD350LC and the square aligment mark for the RD250LC.
As stated this is for engine numbers 4L1/4L0-100101 and onwards.
The change of settings were because the early machines had an issue with over oiling.
The pump minimum stroke was reduced from 0.20 -0.25mm or 8 to 10 thou down to 0.10-0.15mm or 4 to 6 thou and a new mark on the pump pulley was marked 4mm below the original on the pulley.
