Oil injection line locations
« on: February 17, 2019, 04:27:32 PM »
I assume the cylinder oil lines go to the bottom of the intake tract between the carb and cylinder?

Of course mine are blocked off with bolts, one thing after another with this purchase... now I have to search for the nozzles   >:(

Yes, there is a oil port on the bottom of each cylinder on your Invader.  There is also a port on the crankcase behind the water pump.  Unfortunately it appears that the pump needs to be removed in order to install the one on the crankcase. 

You will need nozzles and the check valve "banjos" for each.  The banjos can be purchased from Polaris "Oil system Banjo: Same as Banjo for the 86 Polaris Indy 400. Polaris Part # 3083894"

This may help show the location. If what you see is an aluminum bolt going through a brass circle then you have the banjos and nozzles.
I would highly suggest getting a genuine copy of a Kawasaki shop manual for your sled. Re-establishing oil injection should involve a complete disassembly of the tank, pump, banjos and nozzles for cleaning and inspection. Re-assembling according to the manual with new hoses and clamps and filter. Then adjusting the cable to function properly with the throttle. It's not a big chore but one that will keep the engine lubricated far better than pre-mix.

 I attempted to buy the only shop manual advertised around here but he sold it. $600 extra dollars sunk into this thing already without a single ride and it was advertised as ready to ride lol
One more question . ..


There are two outlet nozzils on the bottom of the oil tank, I assume one loops back to the top of the tank?

I will look to see if I have any spare injectors.

There are two lines coming out of the oil tank.  One is connected to a riser inside the tank.  The one without the riser goes to the gauge.  The one with the riser goes to the injection pump.

Yeah the one going to the oil pump is still on there and the line going to the center bearing from the pump is still connected.

There was nothing on the other outlet

Is the Polaris banjo bolt part # 3083137 the same as the Kawasaki as well?

I'm going to need the two bolts and the washers too...
