Wonder if that's what happened this afternoon?
Went out about 4 PM and maybe 48 degrees.
Tank was 3/4 full and I'd just put in a dose of StaBil so off to the station for a top off maybe 3 miles away.
Fired up after filling up and it stuttered for about 3 more miles and just generally ran like crap.
Plus the damn thing still really "buzzes" at maybe 4 and 6k rpm , ever since I changed the rear sprocket (40 t).
Now that shouldn't have even a remote connection to the buzz, but that's the time line. ???
Now I'm just waiting for my knees to thaw out.
