Re: Older Yami Waveiii oil injection or block off
Woo hoo, my first post! Was hoping it would be on my boat but I am just starting. Have been working on and riding skis for 3 years.
Anyway, the best thing to do is to remove the entire oil injection system.
It is the first thing I do when I get a ski. There are too many things that can go wrong. Your pump can fail or more likely, an oil injection line can pop off. If this happens, you most likely won't know it until your engine locks. Chances of this are small but it sounds like you are already having problems.
To answer your question, on some skis you pump the same amount of oil at any RPM. Most skis will vary pumping more at high RPM and less oil at lower RPM. If you are getting the reverse, you have a big problem.
My first ski was a Kawisaki STX 750. The pump was starting to fail. It was pumping more oil than it should have, smoking badly and fouling plugs.
I removed the pumped, ordered a block off kit and lived hapily ever after.
Not everyone agrees with removing the pump but most people who work on their own skis do this. It is a pain to mix oil but much worse to lose an engine over $0.25 worth of hose that popped off.
Most likely you are looking at a 50:1 on the oil in the premix.
