Give a little more details on exactly what your bike is doing. "fire works" is it just popping on decel or is the exhaust crackling at idle and or is it constant?
Hopefully it just a jetting isssue, maybe pull the carb off and list your jet sizes here so the jetting gurus can see if thats the problem. You will probally want to check your valve clearance also. And get the manuall Good luck

I'd back it if I were you and not accept any of that 'they all do that' cobblers
One quick thing though, just check to see the carb isn't hanging off....

Personally I would not have taken a bike if it did not run.
I have a EURO Spec Bike (I am not in Europe) and though there are minor differences they are not significant - the motors are the same as is the jetting.
The Bike will be jetted lean for UK temps., mine did not run well, and when the dealer started it he had to hold the throttle on. I had to turn the idle RPM way up to keep it running. (Black Knob) The dealer did not know how!!
Riding in the traffic was a nightmare, the bike would not idle well and would run on..I had to let the clutch out to bring down the RPM.
Well, got it home (many months ago) and took the carb OFF: to rejet and install AIS etc. etc. Ran and started great after that...
The biggest diff. for you in the cooler temps will be the #48 Pilot AND an Adjustable fuel screw. GET THESE ASAP and fit. Then adjust the SCREW to 1.5 turns out. I also put in an Iridium plug, not a must but wanted the best..Then Up the idle via the black knob [clockwise] and that will get you running. When warm, adjust idle to "fast" tickover. As high as you can stand 1700-1900. It feels fast but solves idle/start/and "off idle" jetting glitches.
Come back when you have done the mods and we will assist (with advice) on fine tuning.
Hey, if you have not owned a thumper with a FCR carb then my advice is to get use to carb and jetting intimately. Also closely follow the start instructions and never "pump" the throttle during start...too much fuel, easy to flood etc...
Enjoy and good luck

By the way, check the manual and see what the spec is for idle speed. Its pretty fast on these bikes--faster than you would think. Make sure its set correctly.
