Black smoke might result from too rich fuel mixture and/or weak spark.
Would suggest checking compression, valve clearances, and ignition components (you know, all the usual stuff), and setting cam chain tension, then the float bowl fuel level, and maybe some pilot air screw adjustments, ALL BEFORE opening up the engine.
Nice bike! And hoping for you a simple, quick, easy fix.
Yeah, those are all on my list to check first. Thanks for the reminder.
Another thing I noticed this morning, as I was starting my preliminary research, was possibly something interesting with regard to the VIN number.
I looked at the specs for this model on
www.Zedder.com, and saw that there were both US and Japan-made models for this year.
Here were the VIN ranges they listed:
Japan MFR JKAKZCM1vCA004701 - 004800
USA MFR JKAKZCK1vCB500001 - 502002
So, if this is correct, it looks like they only made 100 units in Japan?
I don't yet know the full VIN from my bike (won't have it until tonight), but I do remember that it definitely started with "JKAKZCM1". So, if I'm reading all this right, I have one of only 100 Japan-made M2s?
