Hi all,
a couple of weeks ago I introduced myself as Triguy. Two weeks later
I decided that was too cute, so now it is just David03.

I don't know if it is fate for joining the group that this issue
started now, but my Trident 900 now runs rough at low idle. When I
input a small bit of throttle it runs a a bit rougher. Maybe its
missing or maybe not even igniting. I'm not experienced enough on m/c
maintenance to know for sure.

With still more throttle the engine starts to sound better and pulls
strong, but again I don't know if it is because now its at higher RPM
and masking the problem, ,or if is now firing well on 3 cylinders.

Starting with the most simple things I though it might be some water
in the tank and added about 1/3rd bottle of heet to a pretty full
tank. It idled a little better, but still rough.

If it helps to know, I also used a fuel stabilizer from Oct to end of
Feb.

Any advice would be appreciated.

David 03 aka David Greenspan

Dave,

drain the carburetor bowls - from the right side of the bike, you'll see a
phillips head scred at the base of the carb bowl - you'll need a long
bladed, good head, phillips screw driver to get at all three carbs.

If that doesn't work, I suspect your idle jets are clogged or partially
clogged. You can try a full tank of gas and fuel injection clearer and go
for a long, long ride but the best thing to do is pull the carbs and using a
copper wire (from a electrical wire), run it through the jets.

good advice but I'd try the FI cleaner first and just ride it, even with
the misfire. Those pilot jets are really really small. They may just
clear out with normal riding, say 100miles

Ditto that...before tearing open the carbs try running some "SeaFoam" through,
assuming you never have done that before. It may just clean 'em up fine for ya'
the easy way.

Even if the various additives work, I suggest that any bike of this age is due for carburetor removal and cleaning.

Dave,

one other thing I thought of after I sent this e-mail. Check that the vacuum
connections on all the carbs are either sealed and that the right carb has
the vacuum hose on tightly which runs to the vacuum petcock. A vacuum leak
can cause what you describe, as well. Then make sure the rubber intake
manifolds are secure - both the bolts into the cylinder head and the clamps
holding the intakes to the carbs. Oh, and the left carb's drain bolt faces
the left (I believe this is referred to as #1 as you sit on the bike).
