just a heads up for anyone trying to replace their TPS out of warranty: the local stealer (Central Yamaha for anyone in the N.Dallas area) quoted me $58.50 (or about 45 minutes) for installation of the replacement TPS. I bought the replacement a while ago and haven't installed it yet, since I was dreading the task. so hopefully by the end of next Saturday, I'll have a new TPS for about $60 (plus the $100 or so for the TPS that I paid already). I'll probably call the other stealerships around and see what they quote just to make sure that Central isn't BSing me..
