Yep, had to go back since his sled pooped out. My dragon ran great for about 2-3 rides last year. It would pull rpms, and I love how easy it was to ride. Then I had the chaincase go out twice, egt sensor crapped out, wouldn't pull rpms, the list goes on. Now it seems completely gutless after the update and the TPS sensor might be tats up. One of the most frustrating things is not having a knowledgeable dealer to take it to in bozo. Next sled...I am leaning hard towards the M8 if I can't get my dragon to run. You? My buddy had an older REV chassis and that was nice to ride. I have tried out a couple of the newer XP's, but could never get used to them. If you look around they all seem to have their problems, it is just picking the lesser of 4 evils.
