Even though I have had this bike since April and have done a fair amount of work on it I missed the fact that it has a grease fitting tucked away in the rear shaft housing. I discovered it on Saturday when I had my saddle bag off and I noticed a deposit of grundge on the rear housing near where the shock mounts. Hidden in all the stuff was a grease fitting. I assume it lubs a bearing or a spline of some sort. I cleaned it up and gave it two good shots of grease with my gun however since it appears to be sealed I wasn't sure how much to give it. Any suggestions? Thanks.
