Hello...I'm a first time poster but long time reader of this wonderful site!!! I'm quite new to the biking world only recently getting my license and a new Hyosung GT650R LAMS restricted bike. I was hoping someone could offer advice on a technical issue that I may/may not be having...Today, I had a brand new Micron Carbon Fibre Muffler fitted to the bike. It sounds absolutely beautiful however I am a little concerend becuase when I de-accellerate at times the muffler pops/backfires and shoots out bright blue flames...I have been told by the company that fitted the muffler that this is quite normal for my bike due to the fact that it is restricted however I was hoping I could get a second opinion. The Muffler is a straight bolt-on type and there have been no other modifications to the bike at all. As I said earlier, it sounds great and does a good job of keeping cars well away from me but not so sure if this is normal. Any help/advice would be greatly appreciated on this topic...Thanks.
