What is the cheapest and easiest way to make a 400ex run cooler? I dont want any ordinary answer like, "Get the UM Racing Oil Tank". I also have a problem with keeping my oil tank full of oil. My 400ex doesn't burn any oil either, i know that because it does not smoke. When I changed the oil, I drained both the external tank and the crankcase. I filled the external with a about a quart or so, started it, let it run for 30 secs, and shut off, I then put more oil in and checked the dipstick, started it again, let it run for 30 secs, checked it again, and maybe put another 100ml or so. I then started it and repeated the process, and it finally said FULL. I rode for a little while, came back and it was 3/4 full. Please explain to me why it keeps sucking oil!!! Im using the 20W-50 Synthetic (gold Bottle) oil. I had to open up a 3rd quart i purchased to keep it saying full...I dont understand this one bit...
