This is just one of many that have done this. BDX makes BS stuff and it shows. Yeah some guys have gotten by half lucky. They probably bring the grandmas on trail rides too. The pictures above prove that the only way you can delete the oil injection safely is to regularily grease the shaft. The argument is that the grease can seap to the other bearings. Which is partially true. Seriously guys what do you gain by doing the delete?! not much. It is safer to just leave it and tell BDX to go fly a friggen kite
Thats garbage. Come on, lets get this discussion back on track with helpful information and experience. The pictures above prove nothing, they support a theory, but prove nothing.
People have been deleting their oil injection pumps and/or using mixed oil to lube their bearings since, probably, the very first two stroke snowmobile engines. There are plenty of people with high hp sleds that are running the BDX oil delete kit with no additional lubrication, that have had zero problems. One fellow here locally has over 3000 miles on his sled, 2500+ of which was with a race gas turbo and a bdx oil delete kit.
In my opinion, if you want to be safe, mimic the factory race engines by milling or grinding a port in the lower case and drill a hole to direct some lube onto the brass crank gear. Anybody that has ever drilled a hole with a pistol drill and ground some metal with a die grinder should be able to do this mod, and there are plenty of pictures in the other thread and elsewhere on the internet.
What do you gain? You loose a couple pounds and you gain consistency and reliability. Both valuable in my book.
