Hi everyone. I have a 1985 BMW R80rs with the stock Bing carbs. I just moved from the Denver area (~5,000 ft) to Seattle (~sea level). I'm looking for info on rejetting my carbs to account for the lower elevation. Do I need to size the main jet up or can I make the adjustment with just the needle? If I ride the bike now, it will be lean but I don't know how lean... How fast would I damage my engine by riding it like this? Thanks in advance for your help!
