I built my own blockoff plate out of a piece of alum., no graese zerk but probably wouldn't hurt. You loose 4lbs from sled and cleans up under the hood. With premix you now that it is the correct mix and not have to worry about oil pump failure, or uneven oil distribution. Ran it for 2 years like that on a 1150 cutler.

Pobuda, You should be able to run 50:1 in your tank and oil injection. Your plug life will be shortened so carry extras in case. More oil will make more compression/power and will also help the engine run a bit cooler. I am doing the same.

You need to lube the water pump/oil pump shaft or it will seize. The way you do this is to drill a hole next to the hole that oils the inside PTO bearing down into the cavity.

This will allow oil to drip down and lube where the water pump shaft gear mates with the crank.

If you have any other questions pm me and I'll try to explain.

Here is a pic of the case mod. The top or upper hole is to be drilled at 7/32. The bottom hole is the factory crank bearing weep hole. A good selection of carbide burr bits is very helpful. NOTE! no matter how careful you are to not drop metal chips into the void which is the crank gear/water pump shaft area of the lower case, as the bit goes through, some will fall in. I suggest to pull the cross shaft, and clean very carefully all the chips that fall where they may down there. Also, dump an ounce or two of good synthetic oil into the cross shaft area so as to provide an oil bath.

2x4, the arctic cat doesn't use the oil pump to inject oil directly on the bearings like a poo. Instead it injects oil into the pump and the oil in the fuel drips down holes in the top case half where it lubes the bearings. The only thing on a cat that the oil pump oil's directly is the water pump/oil pump shaft. Drilling the hole as shown in the pictures allows for this shaft to get oiled and your good to go.
