I have a 06 Springer Classic w/ SE stage 1 setup ( filter etc.), V&H Slip On Fishtails, and the Stage 1 download. Problem I have is popping and backfire thru exhaust on decceleration. Went to dealer that did the install and was told that the 1450 download did not take and would have to bring it back in. The tech would have to hook it to the computer, get the necessary data to send to Harley so they can approve the 1550 download ( recomended by Harley for the 06 if the 1450 download doesn't take). Should I be riding if the download is not working? Am I running with too lean a mixture to do any harm??
Thanks in advance!!

 

No, the bike is running lean. Leave parked until fixed.
