I spent the holiday at the dunes and did a ton of ridin over 3 days. My last ride my bike felt tired. The power was down and it felt like my clutch was slippin, anyways I called it quits after that ride. When I got home last night I noticed the screw that tightens down the clamp around the reed cage boot and carb was gone. I pulled my plug and it looked lean, not white...but just lean. I pulled my carb and reeds and no sand got anywhere. Should I pull my head and check the piston and cylinder??
