I have read that dialing in the jetting is difficult on that particular model.
That's nonsense. If you can't get this bike jetted right, it's your skill set not some inherent flaw in the design of the bike.
If the exhaust is sealed properly it will always pop a little on decel when these bikes are jetted CORRECTLY. Guys who set them up so it never pops are running them way too rich, and then the go on the internet and bitch about how this bike is tough to jet. Nitwit logic at it's best.
If you pull the choke on decel on a bike that might already be too rich it kills combustion to the point that it probably won't pop even with an air leak at the exhaust manifold. You can't draw any really useful conclusions about the jetting until the mechanical issues are sorted out. So start from zero when it's mechanically sound, and don't assume anything.
Make one change, test it, document it, and then make another till you get the characteristics you are looking for.
One rider in fifty that I meet actually knows how to jet, but 49 of those 50 have an "opinion" that they'll swear is a fact about the subject. Take everything (including what I say) with the appropriate sized grain of salt. ;)
