Pulling jugs without removing engine from frame...

[Older-twin]

My '91 Sporty needs base gaskets and I was wondering if I have to pull the engine like the service manual says.  It looks like I might be able to get away with just pulling the heads and taking out the studs to get of the jugs off the pistons.  Can removing the jugs be done this way or does the whole engine need to be taken out of the frame?

You can remove the cylinders without removing the engine.  Don't need to remove the studs either - just the rocker covers, heads and then you can lift the cylinders off the studs.

yep that's right, no need to remove the engine. Funnily enough the three piece rocker design was apparently a last-minute change before the intro of the evo BT in the early '80's or so I have been told, without that it would have been difficult!
don't forget there's a few important things to remember with the stripdown - taking the pressure off the lifters slowly and correctly, also the same as the stud pressure is relieved too. The HD or Clymer manual is excellent for this procedure.

Thanks for the info guys.  I'll be sure to study up on releaving the pressures off the rods and studs before I tear into it.

make sure you disconnect the battery too.  If you don't, the rear rocker box may get a spark mark from hitting the battery while removing.  at least, that was my experience.
