kinda strange - buddy has DO 2 and he done some gaps today, no flats, no air preload, fork done about a half of its travel. ive checked it and it looks like left leg internals are blown OR theres lack of oil. SSV deosnt work, i can push it much softer than mine DO, rebound is much faster. right leg looks fine, but i cant be sure about this. so, questions are:
1. could this be blown internals or just a lack of oil;
2. if its lack so how could i check oil level (how this could be done) ?
