Hey Guys. Just wanted to find out if this sounds alright. My 2012 Roadster is 100% bone stock, not a single thing has been added or removed from it. This is my first non V-Twin motorcycle. On my previous bike I had a TRE and a FI2000R and I got amazing fuel performance out of it, super smooth.
I just notice that when I am engine breaking on the roadster, from 3000 to 1500 rpm or so I can hear some decel popping but its very quiet, it kind of sounds like this if you imagine "Vroooo ooo ooo ooo ooo ooo ooo ooommmmmmm" with evenly spaced gaps if that makes sense.. Since I dont have a fuel controller can I assume that this is a condition happening because of running lean?
I don't think anything is wrong with the bike but just wanted to make sure that sounds normal... I also notice that if I am coming to a stop from a fast pace to a quick stop, the RPM's drop down to around 500-600rpm and sound like its a little out of breath but if you leave it it just gradually gets back up to 850rpm and idles smoothly. It hasn't stalled at all on me but again, just wondering if thats how other peoples bikes are. I have 1500kms on the bike in total.
Other then that, it runs supremely smooth while accelerating and cruising, no popping or uneven operation.
