I'm running a nels tune meant for a bike with the ram air filter and tors. I currently have triple K&Ns and an open megaphone type pipe. Lately i've noticed a burning smell when I come to a stop and the stock heat shields are making much more of a tingy sound when I shut the bike off. The bike feels like it is running great especially right off of idle and isn't as loud as the Hanso tune I had in it before. After running about 100 miles I was happy to see I've gone from 25 to 35mpg. I don't hear any detonation other than slight decel pop which is also less than before. Need I be concerned that I may be causing my motor damage by running too lean? I've also kept the O2 sensor on after the 12 minute tune hoping that it would aid in fuel economy since most of the time I'm just cruising barely on the throttle. Any help is appreciated.
