Hi,

After the rainy season here I started riding my FJ1100 to work and
back every day.  My problem started when I would come to a stoplight
or stop sign.  If I sat too long with my foot on the brake, the bike
would sputter and die.  As a quick fix, I atttempted to up the idle a
bit until I could address the problem more thoroughly.  But upping the
idle only a small bit made the idle unstable and it would jump up to
1500 to 2000 rpm and then settle back down after a minute or two.  I
took my bike to a friend's house and he and his car mechanic buddy
took it down to the carbs to see what they could find.  The only
specific thing the mechanic found was one of the set screws against
the choke bar was missing.  We replaced it and were not able to make
any more headway.  Today, I was riding home from work, my first ride
since getting the bike back, and the idle jumped up to 1500 once the
bike got warm and stayed there.  It did not do this on the way to
work.  So now my choice is a bike that stalls or a bike that idles at
1500 or above.  Any carb experts out there than could give me some
good ideas before I take my bike to a real bike shop?

Thanks,
Bob
