Trophy 900 ignition problem

I have a 1999 Trophy 900 that I love to ride. It has developed a nasty stall problem as of last year. The local wrenches said it was a fuel starvation problem. I replaced all fuel lines w/ new stock. Carbs rebuilt and set to specs. Still has issue. I have contacted a guru in MIA and he just had the same model and year in the shop w/ the exact same problem. It turned out to be the CDI box. The CDI new runs $700.00. Any one out there have a good used one for sale? Or know someone out there that may rebuild these CDI boxes? Thanks.

Hi If you still have a problem with your CDI a company called Carmo Electronics can repair/replace the unit. The company is based in Holland. Hope this helps

First, I would check all the usual suspects. Roll over valve, fuel petcock, vacuum line to petcock, fuel cap vent, fuel filters(all three), coils, crank sensor, sparkplug HT wires and caps. All electical connections(side stand switch, clutch switch, ignition switch, engine cutoff switch). Battery condition. Wireing harness around the headstock(broken wires due to pushing/pulling on harness). Also check the plug for the alarm unit located in front of the battery box. Corosion in the plug can cause an intermitent short on the gray with green-dot wire that goes to the Igniter(there is a wire that loops around on the back side of the plug). Check all these things before throwing money at it. Also, the Igniter can be tested at a Triumph dealer. Baxter Cycle ( would be a good source for used parts from breakers. I've heard of someone that has rebuilt Igniters to swap, but I'll have to search for them again, I think in the UK or Europe. Hope this helps.

My 1999 plymouth breeze keeps stalling out... just changed fuel filter and last year changed the fuel pump..

Get your ride checked for error codes, as error codes will be more helpful in solving the problem. Generally when the car stalls out, the problem may rise due to:

1. Faulty fuel spark plugs

2. Faulty ignition coil

3. Faulty distributor

4. Clogged or damaged Air filter

5. And many more

So, it is advised to get the ride checked for error code and then update your answer.

1993 Triumph Trophy 900 will not turn over

Hi, Anonymous before testing any electrical component in the Starting System it is "IMPERATIVE" that you have a fully charged battery of 12.5 volts or more and be able to pass a proper "LOAD" test if necessary, you may have a preliminary reading of 12.5 volts or more but little or zero amperage, the battery is faulty and must be replaced. AGM type batteries fall into this scenario more so than lead acid batteries.
1. Ignition Switch not in the "ON" position.
2. Engine Run Switch in the "OFF" position.
3. Check the battery terminals for damage or corrosion check the battery cables at "BOTH" ends for loose, corroded, or broken connectors, "INSIDE" and outside the cable harness, perform connector wiggle test and check cables with an ohmmeter.
4. Bank angle sensor needs a reset or is faulty.
5. FOB battery low or dead.
6. Faulty ignition switch.
7. Faulty starter button.
8. Faulty kickstand, clutch, neutral safety switch.
9. Security alarm needs a reset.
10. Starter relay, solenoid, starter have failed or circuit wiring faulty.
11. Starter armature or field coils have failed.
12. Main fuse or circuit breaker may be blown or faulty.
13. The electric starter is working but starter clutch has failed.
14. Check for engine trouble codes.

I'm going to say the carburetors are fouled out, changing the fuel in the tank, lines and filter are a good start but the biggest problem is in the float bowls where the gas has evaporated leaving a nasty scale. The scale is chemical deposits left for the evaporating gas and just closes off and sticks the carburetors from functioning. If you have all the other components in making the engine run, ignition, compression and proper timing then the only other is fuel. The best way to fix the problem is to take the bike to a qualified mechanic and have the carbs cleaned and serviced. To prevent this problem I use a fuel stabilizer before putting my bike in storage generally I don't know when this is going to happen so the last three of four tanks of gas gets the treatment before going away for a Canadian winter. This stabilizer helps prevent the scale from building up and is a whole lot less expensive to buy then paying for repairs.

Do I assertain from your message that the battery is not charging? as if your battery is flat there will be no ignition. If the battery is being charged then check the fuel line filter. There is one in the tank inline with the fuel tap. It may be blocked and that moment or so with the engine at rest, may be enough to get you going again.
The battery voltage when fully charged and standing should be 12.8volts. A battery charging should be between 13.8volts and 14.5volts, no higher or else permanent damage to the battery will be done.
Hope this helps.

It starts ok but when im riding it seems like it some times is running on two cylinders instead of the three i have a 2003 trophy 900

Check for water in the spark plug well. 
Probably worth pulling plugs and checking/replacing them.

Intermittant power lose on 1996 tronph trophy 1200. 15000 miles

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.

Coughing '95 trophy 900

I think you would be better of checking the ignition pick-up located on the right side engine cover. you may want consider searching for info on the ignition pickup, as apparently it is a weak link on these engines. That was the first thing i repalced when i got got mine as it had sat for a while.
