I have a 72 750 that has an oil leak on the left side probably from a bad o-ring, and plan on pulling the motor this winter and redoing the gaskets and o-rings.
What I know from just looking at the bike:
-The front right Stud looks to be a few millimeters longer than the front left and it has be thinking of swapping out the studs

.
-Cylinder Gasket has been replaced (at some point), its blue.
If Im going through all the trouble of pulling the engine and changing things, should I just change the studs

. I have no idea what studs are in there, and Ive never done this before. Been looking at every post about stud replacement. I dont wanna torque down the head and snap a stud or have a leaking engine.
Just trying to get a feel for what everyone's thoughts are.
