Greetings riders!
Bought a 2000 Trophy 900. Was having a bit of power issues, and had sat for six months, so I got the carbs rebuilt and ignition coils replaced. I am still having problems with it. Here are all the signs and symptoms
Extremely low power until the bike is hot. Sometimes it feels like it's running on 2 cylinders.
Chokes, coughs, when too much throttle is applied before bike is hot.
Stalls when idling for over 3 minutes.
Full power over 1500rpm after bike is hot.
Occasional SHARP backfire on cold startup
slight bump in tach needle when I press the bes. (A short maybe?)
Other notes: At first, when it returned from the shop it ran fairly well, but the same signs were still present. it has digressed dramatically in the 700 miles since then. On cold days it doesn't want to start at all.
I don't want to waste time sending it to shop after shop, after all, it's old, and has 30,000 miles on it. But it fits me, and as a 6'2" fella that's a rarity and I'd love to keep the bike if I can. It's a great ride.
