hello, i have a 1978 yamaha DT175. what needs to be done to disable the oil injection pump? my bike is missing the resevoir and all lines. i just want to run pre-mix. is the oil injected at the carb? thanks

If i remember right, it is injected at the bottem right side of the cylinder towards the rear.
we used to take the line off there and plug the hole in the cylinder with a screw and a crush washer."you do not want an air leak here".
where it gets injected into the cylinder...does that line kinda look like a ground wire?? i pulled that off, then took off my oil pump and then i noticed that it was like a brake line kinda and had oil in it...
im doing the same to my DT250...i love the smell of premix, witht the injector system it smells kinda nasty, like vegetables, unless my oil was bad...the oil was green when i drained it
If everything is good think about keeping the oil injection. My 69 250 has the injection on it, I love it just put gas in it and ride. I have a couple that need pre mix ,it makes my tractor smoke when I put the left over fuel in it.
Pre mixing is fine and all but one of my bikes runs mixed fuel, but its also nice to have one thats original. I have had a lot of old yamaha enduros and never had a failure with the injection pump there isn't a lot that can go wrong with them.
