Mark's new Trophy question
- About you RPM increase at stops:
My '98 Trophy 3 had a similar, but much
worse, problem when new. It took three visits
to the dealer to fix and, unfortunately, I didn't
find out what it was.
Most times, when asked to idle, the engine
would rev to 1500 to 2500 RPM, sometimes
settling slowly back down, sometimes staying
there, sometimes slowly increasing from idle
to 2K. Every now and then, it would idle like a
charm. No other performance anomalies were
The dealer cleaned the carbs, I ran a couple
of bottles of Gumout through, the dealer cleaned
the carbs again, etc. Finally at almost 1,000 miles,
the fix happened. I think (and mind you, I didn't
actually participate in any of the repair efforts) that
gunk from the new fuel tank got into the carbs. I
remember seeing something on the Triumph list
about fuel tank interior gunk, used to prevent rust
in storage and shipping, causing problems. My
Trophy had its original tank swapped before I took
delivery due to a paint blemish, so I may have gotten
a double dose of tank gunk.
Anyway, I'd bet that a complete fuel system
clean-and-flush - tank, lines, filters, carbs - is in
order. Don't wait. It won't get better by itself. It
is also dangerous and hard on the transmission
to slam it into first gear at 2000 RPM.
And good luck!
Pete, Trophy 3 (who needs more?)
