.020 Over
After having spent lots of meditations,PC III finetunings, disassemblies followed by reassemblies, speculations and suiciding thoughts....
My Triumph dealer in Frederick (Maryland) found the cause of my disappointment... A clogged fuel tank air vent ! The symptoms are a kind of surging engine when riding at constant low RPM (1500-2500) with a stable idle and normal accelerations!
But the easiest thing to notice, if you know that's NOT normal
, is that when you open your fuel tank you hear an important air succion.
I never knew it wasn't normal since I bought the bike with 5000 miles on it and got this effect from start.
By the way, some cars have that on purpose, to reduce the risk of fuel fumes explosion by creating a depression in the fuel tank. But not a ROCKET!!!
The solution has been to remove the oneway valve behind the left cover and now it runs like a charme.:bch:
