One thing I've discovered on the Moss..(before or after treatment)..if you tow the bike any distance much at all.....especially if the elevation changes....when you first start the bike...allow it to idle. Without touching the throttle at all...for several minutes. I reckon it goes into a "learning" mode and does some self adjustment.....sure made a diifference in the way my bike runs.
Another thumbs up to Eurosport Asheville in NC. They know what's what! Rare these days. All that work there seem to be enthusiast too. They like to come to work and it shows.
