Review on Maxima 55901 10WT Standard Hydraulic Fork Oil - 1L Bottle, BLACK: Premium Performance for Smooth Fork Movements by Douglas Davis

Holy smokers! I didn't understand how much this would change the situation. I just fixed a new old bike for myself. The old oil was probably original, 17 years old, smelled like rotting whale carcass and looked even worse. Opaque at a depth of 1/4 inch. Maxima is the color of light vegetable oil through which the legs shine through. Weighing 9.2 ounces per side, 2 bottles will make 3 replacements, 12-15 years, with a small margin. If you have an old Dyna, you MUST do this. BRIGHT! 1 hour in the garage and my first time!
