Just want to hear if this happens with a healthy engine, bike has 1,400 mi. oil changed at 1K, synth oil used in the change. never noticed before,just since the 1K service. but at startup, it puffs some smoke from both muffs, just for 5-7 seconds, and only if its been sitting for hours, or over night. wont do it at any other time.Oil level is ,and has been fine, It isnt coolant, dissipates quickly, and doesnt smell sweet, or vapory. Any thoughts? experiences to share? thanks, Geezer.
