What is the Lentini mod? And what is 0-0 ?

Not to worry on your R100s. BM buys fuel injection systems pre-calibrated
from Italy for their R1100/1200 models. They have a simple pot (variable
resistor) on the throttle shaft that tells the computer how far open the
throttle is. About 1 in 10 of these are off a tad making the bike run
crappy. Bob Lentini's "mod" is simply to reposition of the pot with the
throttle closed so it sends the right 'closed' voltage to the computer like
it is supposed to do and does on most BMs. But the adjustment screws have
"tell tale" paint installed in Italy that perforce gets broken during this
fix so BMW calls it a "unauthorize modification". Replacing the $10/apiece
spark plugs with cheap US ones finishes the job.
