What is fork oil capacity for a 2009 street bob 49mm

I have never seen seals replaced without dismantling the forks. The seal will come in a fork revbuild kit whether the bushings etc are used or not. Obtained separately but necessary in any case are new lower fork bolts and copper washers. I suppose it might be possible to get the seal out of the fork leg without completely dismantling the fork but the normal way of removing the seal is to use the slider as a slider hammer tool to drive the upper bushing and seal from the fork leg which requires removal of the lower bolt and washer and pretty much fully dismantling the fork. You will also need a special fork holder tool or at the least a pair of vise soft jaws and it is critical how much fork oil is added back into the fork as too much will make the ride unacceptably hard and too little will allow the fork to compress too much and be too soft. You also really need an appropriate seal installer to reinstall the seal and upper bushing etc. All that being said:

Just a thought.Aren't late model sportster forks,on the 1200"s,49mm?Check that manual to see if the procedure is the same.If not then guess which one is right.Don't know bout late models but the early mm lower sliders had a fiber washer that could get damaged if the last assembly bolt,allen head,wasn't put in just right.Good luck.
