I ride a 2006 R1200 GSA with almost 19,000 miles. In addition up to trips to the Sierras, many of these miles are from communting to/from work over the East Bay Hills with my track going from dirts paths, fire roads, rural twists, freeways, and city surface streets.
Last week on the way to the shop to install a new gas tank sending unit, I noticed a rather sudden increase in the clutch handle play.
Typically I have about 0.5-1.0 cm of "short" play before the friction zone but suddenly I had about 3.0 cm of "long" play and shifting felt "early" with clutch still in. This happened when shifting for all gears. The clutch does not feel like it is slipping and am familiar with the problem of rotated bark busters depressing the clutch handle.
As I was already scheduled in for service, at the shop I asked them to bleed the clutch. After the clutch bleed, it initially seemed to be working well but after riding for only several miles the increase long play came back. Over the past week I have monitored the clutch play and it still varies back and forth from the short and long play but I have noticed that the long play tends to occurs the longer I ride.
After reading the challenges of dry clutch, especally for a weighted bike on hills, I thought maybe the clutch is worn but why would the play vary so much...
I would certainly appreciate your input as to what the problem is.
