Been making some changes to the setup with Dale's jet kit. Clip now in 3rd groove down instead of 4th down as recommended. (needle drops to lean out mixture)
Adjustable idle air scew at the recommended half turn out. Fuel screw at half turn out instead of the recommended 1.5 turns out. #48 pilot jet. Engine is running well, but feels like it could be a little crisper off idle. No bog or sag when snapping the throttle, but not easy to levitate the front wheel until about half throttle (big fuel tank with about 12L on board).
I *think* it could stand to be leaned out on the pilot as per Taffy's thoughts. My question is: How much fuel screw change is equal to the next lower jet size? i.e. #48 pilot at half turn = #45 pilot at 1 turn = #42 pilot at 2 turns?
The idle speed is not really stable and tends to vary, but always increases and more so when the engine is really hot on the tight trails. Does this variance indicate rich or lean?
After a run down forest roads at about 1/3-1/2 throttle (going back to the truck), the plug shows good colour. Light tan on the outer electrode. Light tan on the insulator. Dark grey on the center electrode.
I put a photo in my gallery to show the plug colour.
I stumbled across an interesting colour chart at this site:
