Backfire
Hello. I have 19 SGS, with Rineheart slip-ons, SE air intake and PV with MotoFuel map. Bike has 3300 miles. I made about 400 of those miles with SE air filter and a map. It was running perfect, without any backfire, but now, I notice occasional backfire (now more often than before ) when I shift gears. Is this normal behavior while things are kind of "unpack"? I could do auto-tune and see if that fixes the issue, but before I do, I want to understand if this is something to worry about?

Check for exhaust leaks first , loose header bolts , clamps , packing in slip-ons . Also , you could try reloading your map and see if that changes anything , then look at doing an auto tune .
