Re: BlackMax runs rough at 1-2K rpms-Why?
What year . . . and which carbs? There are low speed jets, but I don't think that's your problem if you've clean them recently.
Spark advance module, low speed idle module. Yank them both off and have a mechanic set the timing to around 5 degrees at idle and 23 or 24 degrees at WOT. Could also be reeds but I would start with timing.
Plugs should be paper bag brown. I wouldn't mess with the original jets.
Get rid of the oil injection and premix. Also check the condition of the bleeder hoses.
