Bonneville America Forums Forums Technical Forums General Tech Technical Support for 2004 Speedmaster

I have a serious problem with my 2004 Speedmaster. Would like to post for comments.

After riding 60 miles freeway 2 blocks from home driving 30MPH slowed to 10-15 to make a left turn half way into turn the engine stopped, rear tire locked before I could engage the clutch, the bike dropped to the right. The bike stopped another time same trip but this time it was raining pulling up to stop light 6 blocks from home it stopped running but engaged clutch, at first couldn’t get it started, pushed it to the side waited 15 minutes and it started and no further problems. This scenario happened again about a year later, nothing serious waited 5-10 minutes to start. This time if it wasn’t for my helmet I would be in hospital. Please provide some answers to fix problem.

I just went through this. It sounds like the igniter to me. You can spend $600 for one from Triumph or spend $270 for an aftermarket one from Procom.

I remember someone else saying the motor stopped and locked while in like 3rd gear before too... can't think of who it was or what the problem ended up being...

I have experienced this as well, making a slow turn maneuver in 1st, the rev s were at about 1500, ****** near made me wreck, now I stay ready on the clutch.

Most likely a problem with the sidestand switch or wire connections under the tank need cleaning, reseating and protected with dilectric grease.

Good call on the side stand switch, I'll follow through on that advice.Already went through most of the other wiring,I spaced out doing the kickstand.

What does the igniter do? Why would it stop working at low RPM. What test are done to prove the igniter is faulty.
Motorcycle ridiing is hazardous as is. Why doesn't Triumph send out a technical report to protect riders?
I will reconnect and clean sidestand switch or wire connections under the tank using dialectic grease.

Checked kick stand and all connections under tank all connected with dialectic grease. I will go ride it again, but this is flat out scary, more so than when a car tried to move me off the freeway. I don't believe it is the ignitor. Generally the bike runs fine. I have noticed infrequent backfire upon decelleration.

Are there tests that prove electrical connections are working satisfactory.

If you lack a continuity tester you cab solder a wire to each pole of a 12V bulb and you have an instant tester as long as the wire being tested has power flowing through it.

Thank you for your responses, alas I am no mechanical newby. I checked connections under tank. All relavant conections had dialectic grease. Interestingly low voltage side of coil were not snug, so I tightned. Did conductivity test on high tension leads Ohm reading 5. Curious that upon start up I get a clicking sound from the coil. Likely between coil and high tension lead or leads, is this normal?

Replaced Spark plugs with OEM, NGK,on General Principle.

I don't know how in the heck the ignitor could possibly be the problem if the died in my scenario at low to Zero RPM.
I understand how the Kick Stand module works to me this is a red hearing. Either it works or doesn't and it works when engine is running and I drop kick stand. Furthermore, has nothing to do with Low to Zero Idle symptom that seems to cause the problem.

check the plug wires where they go into the coil. A click there would indicate an arc to me.

This might not be the answer to your woes , but take two mins to check out !
This only happened to me once , exactlythe same symptoms . Check the setting of your IDLE needle !! .......... Too far in and very occasionally engine will say thanks but wheres my food and throw a fit . Will only happen with throtlle shut

When your ride is behaving badly, never put her where power alone will lift you out of the turn. Not so scary if you follow this 'limp through bends' rule. Yeah Vera Lynn had the same issue once. Turned out to be dirty carbs. Unlike your case, she would also hiccup while underway at low rpms. You ought to at least drain the float bowls and even clean your carbies. (could simple drop the jets and air mixture screws for a visual inspection.)

Tale care in the bends till you get this sorted!

Ignition Control Unit coul still be the problem. Husband's 04 Speedy has been dealing with this. Procom is really good about making sure the unit you get from them is going to work well for you. It will cause the bike to suddenly shut off, even after the bike has been warm. We've had it out on a long ride, get to the end of the offramp and suddenly it shut off. Fires right up again, when you hit the starter.

Also, when I took it to the shop as the ICU was having issues, I could feel it hesitating in first gear, almost like I was runing bad fuel through it. Funky little box thos ICUs! Might not be able to determine it is the unit without switching out with a good one to make sure. My 2006 America Unit wouldn't work on his Speedy, so you have to make sure it is the right one. 2004 Speedmasters have two different units too, so you might just have to get a new unit for it. We are happy with Procom, and you can map the Unit for better preformance.

Check your rectifier.
