Got one for you guys that's more of an irritant than anything else. My fuel gauge on my 85 Euro 930 has started acting really "arthritic" after a fill-up. It goes down fine, but after filling the tank it'll take a few minutes to get up to the Full mark. Other than being a 25-year old gauge that really doesn't owe anyone anything, anybody got any thoughts on what's going on?
