I just noticed a very strange liquid leaks on the engine pipes near the front wheel. The thing is sticky, jelly-like when hot and gets hard when cooled.
I examined and found no leaks around the upper part of the bike.
I wonder if is there any kind of liquid in the bike has this kind of characteristics, maybe the coolant liquid, or the engine oil, or the brake oil, or just something on the street that got caught up in the bike?
