Almost all supersport bikes coming into the US utilize both of these strategies. :)

I own a Ducati 999 that was lemonlawed because it would stall at stop lights. Super common and happened because of how lean the bikes had to run to pass US emissions.

Google said "random stalls" were kind of endemic to Ducatis. :P Didn't know it was related to the fuel mapping! I had a 1098 which would occasionally (maybe once per month) randomly stall at 0% throttle when braking to a stop. I had a full Termignoni system + race ECU, though. California doesn't do emissions testing on bikes, surprisingly!

I had to put a Power Commander on my R1 because of the aforementioned lean spot. The engine would "chug" at about 37mph (5.2k rpm in 1st gear), which unfortunately happened to be a very common cruising speed. Google showed lots of complaints for other years as well.

I can assure you that the engine on the R1 doesn't chug along at sport bike speeds though ;)

Yes, certainly not. :) https://www.youtube.com/watch?v=HSsP-itS8qI

I commuted to work in San Francisco on literbikes, but on weekends I would head south and open them up.
