Got the followup call from BRP today late morning. Took the RT to my dealer, and they did a BUDS diagnostic. I was there about 15 minutes. The Spyder technician told me that the bike was running rich. Took a ride by the beach, and right as I got home and walked in the door, BRP called again. The dealer had sent the diagnostic to BRP and they found two codes. First code was a bad purge valve, which will be replaced next week. The dealer won't have the part until late in the day on Monday. Second code was a oxygen sensor, but it was explained to me that that code could be caused by the bad purge valve. So they will replace the purge valve next week, and then they want me to put 100 miles on the bike and bring it back to the dealer for another diagnostic. If it still shows a bad oxygen sensor, they will then replace that as well. I was told by the BRP rep that "We are not going away". He admitted to me that the 990 was not meant to be a touring engine, that it was primarily made for the Aprilla. As we all know the 2013 has the frame meant for the 1330, which he admitted was not ready at that time. So, at last I feel that BRP is being honest with me, and is really trying to do all that they can to make the Spyder run & ride as intended. Maybe this will help other 2013 RT owners as well, if it turns out that these issues are common to 2013 RT's.
Sometime next week, I will provide an update.
