An experienced rider hopped on my bike the other day and grabbed the front brake and pushed down on the front. He said that the suspension felt a little spongy. Also, when pushed down hard the front left clunks a little. It doesn't hit anything solid and stop, it just makes the noise and sponges down further. When I bought my bike (2nd hand) I noticed that there was some oil leaking around the top of the left shock. Ive found a pdf version of the services manual so im set. My first plan of attack was to just drain and replace the oil in both forks. Im hoping that the occasional clunk might be from the left one might just be from lack of oil. Any suggestions, comments, recomendations?
