$0.35 part, item 26 in the picture. Same o-ring is used in the 9x0 and SE, so I ordered a couple.
I just received mine today! I developed the same leak (again) about a week ago and after elminating other possibilities and cleaning and watching it closely right after riding, I figured it was the gear position sensor o-ring!! My bike finally turned 40,000 miles last week, and it makes sense as I replaced the first one around 20,000 miles ago. I ordered a few to have some spares on hand. As the bike climbs up in miles, I am trying to have certain things on hand going forward such as:
Clutch master rebuild kit
Clutch Lever springs
Water Pump rebuild kit
Oil sight tube ( I had one fail while on a trip and this was not fun, I now keep an extra one waiting in my bag of tricks)
Various clamps for coolant hoses
Some extra preformed and straight fuel line pieces
o-rings for the gear position sensor
Not having these things on hand has caused me quite a bit of down time because inevitably I will need one of these things the day before I am going to leave on a trip!!!
