If your valves are to tight the carbonbuilding goes on and the compression
goes down. If it are the rings. driving on to long can make them break in
the worse case and that gives a lot of damage. Pour some oil on the pistons
and try to measure the compression again. If it's higher then the rings are
worn. If it's the same it's your valves. Lift the head and grind the
valveseats. A lot of work but cheap.

Since this ABS thing has come up again, I would like to a moment & update my
findings so far. I have been looking into the HU of the FJ1200. They are of
the same time period as our GTS's. I have checked shop manuals,
micrifische,p\n's & pricing. I have even asked the questions on the FJ
club.I even spoke to a few Yamaha mechanics. The findings seem to indicate
that the HU is the same unit on both bikes.( With the exception of mounting
points). FJ owners don't seem to have any problems.Which leads this whole
thing back to maintenance,& storage conditions. I think. Speaking of
maintenance , I called in the pro's to check my engine.(since the comp. was
so low, I wanted their evaluation) A quick valve check revealed 3 exh valves
a little tight. Not a terrible thing. However the comp. moved up barely.
Further consolidation they came up with theories ranging from slightly bent
valve(s),excessive carbon biuld up (hence the terminology IDLE
QUEEN ),sticky\stuck piston ring(s) (probably comp) etc..... the debate goes
on.Folks you know what I think. I think I should just take her for a nice
long BOOT,(when the weather gets good of course) which should clear things
right up I'm pretty sure.Peter Piazza
