“We all know that you will lose RPM if the oil is over filled. Well, I learned this weekend that it can also cause the ski to shut down and/or go into limp mode. My RXP-X was over filled from the dealer, but the RPMs have always been fine, so I didn't mess with it. But at this weekend's Supercourse races, it kept shutting down and throwing the "oil" message. At first I thought it was a bad OP sensor. But after draining the oil down to the correct level, the problem resolved. So even if your RPMs are good, make sure to keep the oil level between the bends.”
