TT600RE-Loose valves and a white plug–pics and questions.

[G600]

Hi all


I adjusted the valves on my 2005 TT600RE tonight and took a look at the spark plug. It now has 12.000 km on the clock. I just love to work on this bike, everything is sooo easy..


A few questions:


1.There are three unused connectors under the tank. Does anyone know what they are for?



2.The sparkplug looks pretty “white” (lean?) to me. I was hoping for a little more brownish color. Does this sparkplug look like it should?



3.The engine feels like it has a “flat spot” (lean?) in the powerband just before the second carburetor opens (I think). I did adjust the screw, to make the second carburetor open a little sooner. Has anyone played with this screw? Results?




4.Both of the intake valves and one of the exhaust valves were loose (too much gap). So three of the four valves had too much gap. Strange. Is this normal for this engine? (I expected the gap to tighten)
