Question about 2000 Triumph Trophy 900

Intermittant power lose on 1996 tronph trophy 1200. 15000 miles

My 96 trophy starts fine and runs great except for breif periods at highway speeds when I will throttle up to pass a vehicle for example, and the motorcycle will not respnd or will bog down or will even stall. This will happen and then it will be fine for a long time. I brought it to a machanic and he could not get it to happen. He said that I should replace the ignition moduals. He works on older triumphs and I don't think he really wants to spend the time on this newer machine. The closest dealer is 60 miles away so if its somthing simple I want to take care of it myself.

Hi and welcome to FixYa,

To my knowledge, most bikes of this class would exhibit the problem you posted if they have loose/faulty:

  • RUN or KILL engine switch;
  • side stand switch;
  • or as the mechanic thinks, the CDI.
You can try and verify by simulating the first two possibilities by riding on a straight road at regular speed and with no traffic.
  • Accelerate as you normally would then switch off the RUN; do the same for the side stand, even a slight extend from rest position would kill the engine.
I doubt if it is fuel related as normally, there would be hesitation and starvation before finally stalling.

Good luck and Thank you for using FixYa. Happy Holidays.

Most likely your coils. Try nology profire - much better than the pvls triumph fitted as standard. The symptom you describe is the coils.

Not getting any power unless choke is on

Only running good with the choke on is an indicator that the bike is normally running too lean. The fact that it runs good with the choke on at least tells me it is getting fuel to the carb(s). Therefore it seems probable that there is clogging in the carburetor jets or there is a big air leak between the engine and carb(s).

I have a 96 suzuki savage that started out with some lifter noise. when riding into work today it ran fine the fist 5 or 6 miles then it loss power in all gears it seam to idle fine and didint backfire.

You may be running low on fuel, turn fuel valve to "Reserve" or "res" setting.

Also, your fuel pump may be bad. The front carburator is higher than the gas outlet so there is a fuel pump. i believe it is located just between battery and back wheel. Look for the fuel hose routing to run back there.

Good luck

I aquired an 83 750 midnight virago that sat for 5 years and has only 8000 miles on it. I removed carbs and had them cleaned at a very reputable shop. I reinstalled them and the bike would start and run...

If it stops when put in gear it could be the side stand switch, If this switch is dodgy it could cause intermittant problems.
but this doesnt fully explain the no acceleration problem

Loses spark intermittant

100,000 miles? Maybe rebuild time!! You sure it isn't something simple like a plugged gas tank vent? (Try it with the cap off) Bad plugs? Wires? Coil? Plugged fuel filer or in-tank screen? Are you absolutely sure it's a spark problem and not fuel related?

Sputtering at low speeds and takeoff

your low speed jets are stopped up ,the carbs need cleaning, go to walmart a buy some SEAFOAM, poor it in your gas tank ,start it up on choke, and when it start ot clear up take it off of choke, or ride it until it clears up. after it starts running good get it synchronized

While running at highway speeds my 94 sportster lost power

Sounds like a bad coil, you should be able to have it checked at a bike shop.
