As thread title states, my 1982 R100RS is running erratically after 2 miles. What happens is the bike runs fine until it warms up and then starts to "lurch" and run erratically. What I have done so far is: opened and cleaned Bing carbs...twice...the second time installing new o-rings and gaskets. I've checked timing, valve clearances, run compression test, checked fuel lines. My next diagnostic suspicion is choke linkage, but I am wondering if anyone can steer me in directions I haven't considered. Diagnostics have never been my strong suit.
