Swing arm bearings? adjust? check? replace?....I've got 70,000km, was just wondering if I should start thinking about it coz it is not in list of items to service on regular basis.
Second. Do you guys think a power comander properly maped might smooth out the engine surging at 3-4k rpm? (my starter valves are adjusted to spec) thinking about doing this to richen up the mixture coz I have an acro pipe and a K&N filter.
