i'm looking for a in-depth guide on how to tune carbs on a f650, has anyone ever done one?


do i need a wideband o2 sensor? i'd like to get my carburation perfect to have the best compromise between fuel efficiency and performance. i've only tuned carbs on small 2 stroke engines, with very simple carbs. and i've done so by feel never actually tuned precisely.

I dont think you can get them perfect. Changes in conditions such as air filter, air pressure, fuel etc will change the tune. Carbs are good and reliable but always a compromise.
