Just picked up an 07 yz450 used from a dealership so she's just had her pre flight check. I've only been out on it 3 times (so three cold starts) and the last two of the three the bike has leaked about a tablespoon of coolant onto the ground and then thats it. It only did it with the first start of the day, and the temperature between day one and two dropped quite a bit (first leak was on day two) and then came back up again between days two and three, leaked again on day three. I checked the fluid level today and it is where it should be, perhaps a touch high if anything. It is hard to tell where exactly the leak is coming from due to the skid plate/plastics/little bit of mud but its seemingly coming from the bottom right side of the engine, rite at the front. However, it could be trickling down from god knows where and only visible when it hits the bottom of the bike. Anyone run into something like this before? I have a feeling its just something to do with the overflow and its being caused by temperature changes (10c above freezing to 5c below freezing) and am expecting it to stop shortly, but I figured I'd ask anyway. I've let the bike run over dry ground for a while and the drip is only in the first 20 seconds or less of running and ONLY on the first start of the day.
