I purchased this bike recently with only 12,000 miles. Exterior is in excellent condition, but I noticed a slight knock or tick from the engine when first starting it, it seems to go away when warmed up, so I figured it was maybe in the Timing Chain or Valve Lash. But one day, while still cold, the Clutch grabbed and then slipped, making almost a griding noise. After that, the noise was gone, even though still cold. I believe the noise is in the Wet Clutch. Can I access it from the side cover to inspect it and see what's happening in there after draining the oil? What special tools if any will i need?
