My BX2200 was getting too hard to get out of low range, so much so that something had to be done. A bit of searching lead my to this thread. Love TBN
As per this thread a few shots of WD-40 and it actually glides between the settings. When I do some serious servicing I plan to take off the rear wheel on that side, clean up the WD40 mess and put a bit of grease on the cam!
