Has anyone made modifications to their front forks for improved handling? I had some experience my last ride which made me think things were not quite right. I've been riding the hell out of my bike and admittedly, I should look into the adjustments available for the stock forks... but I haven't. Essentially, I had a couple of moments of an unstable feeling during cornering that aren't related to traction or steering shake and I can't quite put my finger on it.
