Somebody hopped on my bike today who was rather heavier than me. After springing around the car park bouncing both front and rear suspension he left me along, however Ive noticed my rear shock seems to be lacking in air. I’ve pumped it up and it seems to be holding so do you reckon I need to get a service kit and replace the seals or could it be a one off air loss due to the size of the guy being heavier than the shock was set up for. Don’t particularly want to go to the expense of a service kit if I can help it as it’s up for sale.
