I'm at the tail end of a sled over haul and when i got to the oil reservoir i found that i have what looks and feels like sometype of gel. Little chunks all over the place. I only use good BRP oil in the sled. Its stuck to the inside walls of the reservoir. both carb and brake fluid does little to clean it off. Is this stuff bad? I would think it would just clog up my filter and i would never know till the damage was done. ?????
