REPOST FROM GTS LIST to FJR List.......

One of my concerns is that the FJR is not an oil consumer like most GTS1000
engines have proven to be. I can burn a half of a quart in as little as 500
miles when running at sustained high speeds....especially on hot days.

On the topic of GTS oil consumption,  an interesting realization that both
Dave Biasotti reached during the Mexico -Alaska Rally.  The GTS appears to
have too small an oil cooler, allowing the oil to heat up too much and
reduce it's viscosity.  It is probably the root of the GTS's oil consumption
problem.

We both experience greatly reduced oil consumption when running at cooler
ambient temperatures during the Rally.  Enough so that we both commented
about when we had a chance to talk after the Rally.  Dave is looking into a
larger after market oil cooler to address the problem.  I am sure Dave will
post his findings.

Hi guys,

a german bike magacine made a endurance test with the FJR1300.
After 50.000 km they reduced the engine in ist component parts.
The result was unbelievable.

The crankshaft was absolutely as new.

In the oilpump, there was no trace of rills. Obviously the motors get
scrupulously cleaned before mounting.

The gear box showed not a bit of pitting.

The clutch is good for more 50.000 km.

The pistons were faultless. No fetch and the tension of the piston rings
were in best conditions.

In the cylinders you can see hone-traces, that means there is no wasting.
Only the outlet valves were lightly leaky, but with no effect to the power
or the compression.

I think Yamaha has developed a very trusty motor.
By the way ther was no oil consumption to observe.

Greetings
Helmuth
