Pulling an engine in most large displacement motorcycles is a tough job for the homeowner who is not set up to do it. At a minimum you will need to build a jig out of wood to hold part of the bike in place while you drop the engine out of the bottom of the bike, or in some cases, slide it out the side (using an ATV type of jack or some other jerry-rigged set up). That is a lot of money to pay a shop to do it, however.
The question you have to ask yourself is: do I have the disposable time to spend on this project, including hidden or unexpected issues that may substantially increase my forecast of time required to finish it? (and can you just let it sit part way disassembled if you don't have time part way through the project?). OK, that is two questions. Sorry.
On the forks, this is what I would STRONGLY recommend: call Race Tech. You can Bing or Google them and get the number for them in California, call and ask where the nearest Race Tech shop is to your location. They are all over, some in garages of guys' homes. Also ask them if they can rebuild your forks. I think they probably will say they can. When you rebuild them through Race Tech, they can put in the correct springs for your body weight and change the valving if you wanted a more controlled front end for better feel. On the other hand, they could make them feel mushier if that is what you want. I personally like a firm feel for going through turns and for braking. This is also controlled by the compression and rebound damping, which again can be modified by them to suit your riding style and body weight (and any extra weight you carry on the bike).
You will have to remove them, and to do that you have to jack up the front of the bike at the front of the frame and take off the brakes, fender, etc. and then remove the forks from the triple tree. I would mark where the forks were placed in the triple tree on the tops of the fork tubes before removal, using masking tape to show the exact location, or use a Sharpie and make a line. You can remove the marker ink with a solvent like Acetone or Toluene (I prefer Toluene).
Yes, I have used Race Tech to rebuild both front forks and the rear shock on a motorcycle. The results were very dramatic. They changed the valving and the springs to match how I rode the bike and for my body weight. I also have used Lindemann Engineering (also in CA) to rebuild front forks on another bike, and they came out so good, the handling of the bike was about 500% better than it was before. I had real mushy forks before that work was done.
