1978 Kawasaki KE 125. I'd like to dissconnect the oil injectio system to the cylinder and just mix the gas/oil. What's the proper ratio given todays new hi preformance oils and what might be the best oil brand and type to use.
Thanks
Dan
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!

Please remember the Fixya button if my efforts are respected?
If you don't want to buy a bypass kit,Just pull the side cover over the pump,unhook both hoses,put the cover back on,drain the oil mixture tank or remove it,
Safe Starting spot is 30/1 and adjust as needed(if it smokes to much come down on the oil 1 level at a time.
All 2 stroke oil for motorcycles are about the same(none are really any better than the other)
Please rate this fixya
Open up the "injecter"pump cover and remove drive gear,or plug hose coming out of oil bag.
next,try "golden spectro 2stroke mix oil"at 40-1.
I would be carefull doing this,no telling if the main crank bearings will get proper lube,being the injector normaly takes care of them!!.
you MUST plug ALL hoses(mix oil)otherwise you risk sucking air into the crank area(BAD THING!)
you have a "single",you cant eliminate the pump in a "twin"(or more)cyl bike,the crank support bearings on these multi cyl engines MUST be force fed oil!!
