I just put mine back together and no, I didn't do the hone or the ring replacement. Ursula only had 9100 miles on her when I tore her apart. She seems to run fine. AFAIK, there is no gasket "kit" for the bike. You'll have to order the gaskets separatly. However, if money is an object, you may be able to use high temp RTV instead of gaskets. I know of several people who have done this with no ill effects.
It cost me about $150 in gaskets and O rings. I used a combination of
www.ronayers.com and Bike Bandit to order my parts. Ron's prices are cheaper but he charges more for shipping and takes about a week just to process the order. Expect about a 2 week turn around from order acceptance. Bike Bandit charges more for their parts but shipping is about half of Ron's and they get the parts to you quicker. It depends on how soon you want the parts and whether the cost difference is worth it. I used BB when the cost diff was only a couple of bucks. Both worked out great for me and you will end up ordering last minute parts that you hadn't thought of or that broke during install or removal.
Have fun and enjoy the learning process.
