Subject: problem with motor at higher speed
Hi @-Friends,
I have a problem with my @ RD04, which I can't solve for my own. Perhaps
someone of you has the right idea.
A short description of the problem: Up to a speed of about 120...130 km/h
the behavior of my @ is very normal. The
temperature of the cooling líquid is in the lower part of the temperature
meter (around 1/3). But when I go faster (range
140...170 km/h) for more then a few minutes and when the weather is warm,
the temperature of the cooling-liquid rises
until it reaches the middle area of the temperature meter. And then the
problem begins: the motor begins to
sputter (Stottern). The sputter exists until I reduce the speed. After some
seconds at lower speed the sputter
is completely gone and I again can go at faster speed. But a few minutes
later the same game begins.
I checked up to now the ventilaton of the fuel-tank (ok), the carburetors
(dirt or something else, seemed to be ok, I
cleaned them ), the sprit-filter (new one) but there was no change. I now
think, the problem correlates with
the motor-temperature, because at cold weather the motor temperature doesn't
rise so much and in this cases,
the problem doesn't exist.
This year in April I took the power reduction (a metal plate in the
connection between motor and carburetor) out and
now I am owner of 60 hp (before: 50 hp). I hoped, that this would solve the
problem, but it changed nothing.
Has someone of you an idea to the reason of this problem? Or is this a known
problem and there exists a
solution? I would be very grateful for every hint, which brings me closer to
the solution.
best Regards
Klaus
