You have a 29 year old motorcycle, working on it about 2 years so far, and you need to ask for torques?

Don`t you think it`s about time you bought your own service manual?

What's up guys I been posting the progress of the head gasket replacement on the Fatboy got it back together and it was running good took it for a couple short rides didn't get on it hard or anything and my from head stated leaking again fingers crossed my studs didn't pull out of the cases I'm getting ready to tear it back down check the head bolts and re torque if needed but with it being a 94 those are weak cases so I'm preparing for bad news but hopefully from what I hear sometimes u have to retorque the heads after u ride and get it up to temp I will post what I find when I get the rocker boxes off might be replacing the cases or re tapping mine

Hey fellas so I'm pulling the engine on my 94 Fatboy to get some work done on the cases everything was pretty simple until I got to the rear motor mounts I'm down to the last one on the primary side and it's killing me lol I can't get a socket underneath on the nut am I missing something? Is there a trick to this or am I just a dumb a**? Thanks in advance

That's how I did the brake side but the other side the inner primary is in the way I tried getting around taking it off but I'm going to have to my plan was to leave the primary bolted to the transmission and pull the engine but it's not going to happen
