Bike needs to be straight up. Pull out over flow plug on side of "kicker" cover. Should get just a little oil wanting to come out.

Tech tip: I use the handle from of a gallon jug of milk to fashion a perfect funel into the tranny. Also, makes life a lot easier if you can make some sort of center stand that fits under the frame rails. I happen to have a cheap lift that a friend welded up for me.

 

I pulled the allen screw from the side of the transmission kick-starter. There was nothing. I opened the screw cap on top of the tranny and put almost a quart of 40wt oil in there until it started coming out of the inspection hole. I stopped pouring, put the inspection screw back in and the tranny fill cap back on. It's shifting much smoother now.

Thanks again for all the help.

 

DUDE! Either you were running the thing dry before (not likely unless somebody drained it on you) or you didn't stand the bike straight up to check, which means you're way overfilled now. And, 40 wt is NOT the recomended oil for the transmission. Use a transmission specified oil that is 85w140. I use Bel-Ray.

 

Well it had been sitting for quite a few years and I did stand it up to check it.
I have an HD service manual for the bike and it says to put 40Wt oil in it. I thought that was a little light too but that is what it calls for.

Thanks for the info Shovelhead
