countershart sproket spoogle...

[Alex401Smith]

recently looking at my bike, have not been ridding for about 6 months, and looking my bike over, noticed a lot of oil under and around the area, i dont think it is just chain lube.

so, the question, what is the o-ring called? i mean the part number, and such. also how often should this be replaced?

thanks, alex.

There is a special shaft seal and (2) 25x2 o-rings.

Check out the parts manuals for the part numbers...

Go to user manual, then part list.

When they start leaking excessively it is time to change them.

I grease my countershaft to prevent rust, which can really impair seal replacement.
