400EX oil level with FST oil cooler

Recommended Posts

My 500EX motor was already broken in and heat cycled. It was sitting for a month with an occasional start and idle.

After a hard ride at a mx track I checked my oil level with engine oil temp at 250* and the motor shut off. The temp never went higher than 250* (cooler works great!) The oil was near the top of the tank. I let it cool down for an hour and the oil level was at the top of the crosshatch section (max full). I went back out for about 20 more laps and went back to the staging area and the oil was seeping out of the dipstick o ring. i have an aftermarket dipstick with a temp gauge on it. I removed the dipstick and oil started to overflow.

I havent ridden it since then (no time) but checked the oil and its back down but above the full crosshatch area. I dont smell it but could it be possible that gas ended up in the motor from a sticking float. When I towed it to the track I forgot to turn off the petcock and actually left it on reserve. its now shut off.

after about 40 laps I have about 3/4 of a tank is this excessive or ok?

I was told to keep it on the conservative side till i finished a tank of gas.... That lasted for about 10 laps. The rest was me just hangingon (thumbup) to the bike like a flag in the wind lol. Its quite the beast of a bike but just unsure of this oil problem
