Troubleshoot 1978 Yamaha DT175 oil injection pump

Just curious what the manual states. As to how much oil should be produced from the oil injection system on a 78 Yamaha DT175. I have my own ideas on how to see if its working. But I also know that it should produce a certain amount at different throttle settings. Like ex amount of drops per minute. But I havent got a manual and Im at a loss.

SOURCE: How do i disconnect the oil pump/injection system, Fuel oil ratio

Hi Dan,
Why do you want to disconnect the vital oil supply? If you are experiencing too much blue smoke or plugs oiling you can adjust the amount of oil fed to the engine via the secondary oil pump cable,the one that splits off from the throttle to the carb.
If you disconnect the cable it also stops the oil pump sending oil to inlet, winding out adjuster increases oil screwing in reduces.
As for ratio? trial and error as No knowledge/specification is available for Oil injected engines, poss 25:1 to start but don't blame me if you seize?
Quality synthetic oil is always a must, did you know you can also purchase smokeless two stroke oil?
Good Luck!

SOURCE: Will any other carb fit on a 78 yamaha xs400

I have swapped carbs on older bikes before with good results. The key is to stay close to the original size carb, compare to the original and see if they are close. If you don't have the original, call your local dealer service department and ask them what the specs were. They should have the info available, and in my experiance with dealers they have always been willing to help.

What oil in crankcase of dt175 about 88 model


Use 10w40 motor oil in the gear box. Don't use any synthetic oils, oil marked "EC", or oil with "special" additives. Stick with the major brands; Pennzoil, Quaker State, Mobil or Shell.

Use TWO STROKE ENGINE OIL in the pump. If not using an automatic oil pump, then mix the gas and oil 32 to 1. That equals 4 ounces of TWO STROKE ENGINE OIL to one gallon of gas. NEVER use motor oil in the gas. Only two stroke engine oil.

A “very helpful” rating for this answer? Thanks!
