How much gear oil in a 1992 Vulcan 750? Need a volume. How full to fill it.

the oil drain plug is in a recessed pocket at the bottom of the oil pan you need a 17mm socket to remove it

i think you need to overhaul the engine transmission of your vehicle. and replace the 5th gear. ..

The fill plug is located on the left side of the engine. Here is a link to a pic, it is part number 16115

Firstly run your engine till you reach its normal running temp .The engine drain plug will be found under neath the engine normally at the lowest part .Warm oil drains out of the engine much more quickly that cold oil ..when all the oil stops dripping then remove the oil filter ,make sure that the sealing ring is removed ,take care the oil in the filter will be very hot .replace with your new filter make sure you do not cross thread the oil filter unit and any seals have been fitted . Refit your drain plug and fill up to the required level . start engine ,your oil level will drop because the oil filter will fill up and the new oil will be pumped around the engine. make sure that the engine level is topped up when all the oil has reached all the parts of the engine .Do not over fill the engine as this will cause unwanted pressure .and oil leaks .Remember to replace the oil filler cap and that its tight .

you must have a fault with the sensor buddy replace this or the connections are not in correctly or is this the oil pressure light

i had the same same problem with my 1992 vulcan 750. more than likely it is your reserve lighting devive located on the right side battery box. have you had a problem with your regulator/rectifier lately or a power surge of some type?

there should be a little window just below the oil fill area that says high and low, that's where you gauge the level of oil you have. it's not a dipstick, and not very precise, but that's it.
