Dyna 2000 ignition, how good is it?

[Reinhoud]

Gentlemen,

 

I've got a Dyna 2000 ignition on my bike (GS1000) for about 13 years now, only done about 20.000km.

I've heard different stories about it, one says it's good, the other says it's crap.

Lately my bike has some weird problems, after a while, when the engine is properly on operating temperature, it gets the symptoms of an empty tank. First I thought it starved of fuel, couldn't find anything, but of she went again, like nothing happened. This happened a couple of times.

 

3 days ago it happened again, but a bit different, this made me think it's the ignition.

Took it for another test ride, and again, it started run like s**t. Turn the ignition off, wait 30 seconds, start it, and it goes like nothing happened.

I took the trigger off, cleaned it, had some oil on it, tested it with a multimeter and a heat gun, seems alright. No expert by any means with electronics. Resistance drops, but not a lot, from 940 to 810.

Today same problems, turn her off for 30 seconds, and afterwards she went again like nothing happened. So I thought, how far will it go now?

About twice as far as first, but it started to run like s**t again, but much worse! Again symptoms of any empty tank, pulled fuel hose off, plenty of petrol coming out, pulled spark lead off, it sparked...

After about 5 minutes she took off like nothing happened...

 

Just found this. Anyone knows if this is true? I've got a Dyna 2000 with 4 1.5 Ohm coils

Now my number 1 suspect is the ignition module, because after turning it on and off it goes ok again. A stuffed trigger or coil wouldn't do this? Would it?

Also, when my GS wouldn't start, I have to turn the ignition off and on again, and then it will fire up

 

My question, people who had problems with their Dyna 2000's, what sort of problems did you have?

 

I have an ignition of a GS850 lying around, I'm going to put that in to see what happens.

 

Thanks

My Dyna 2000 has worked flawless for over 2 years now on my Kat. If she doesn't start on the first or second try I have to turn off the key and back on again or there is no spark. The box does need to be on a cushioned  mount.

Have you checked fuel filters if you have them and the gas cap vent?

Why did you add a picture of 1.5 ohm coils which aren't suitable for use with a Dyna2k and you think you have an ignition problem . . . . these would definitely cause one!

I've had 4 Dyna2k's now - the 1st one I bought when they 1st came out and was still working fine when I sold the bike 15 yrs later. Only ever used with green coils but I know grey's work ok!

Mine has that too.

 

Checked it, all seems to be fine..

I contacted the seller, he said he had only a few coils fail over the years.

I've got 2 sets of 2 coils, twin spark, both sets are in series, a incomplete information in that ad.

One hand it has all the symptoms of a faulty ignition, the other hand a lack of fuel.

 

This weekend bypass the fuel pump and remove the uppipe and see what it does

My dyna ignition lasted a few hundred km's before one of the pickup's gave out. I tried to contact dyna about it but they don't sell any parts by themselves and I didn't wanna buy another kit at full price so I'm back to points untill I redo my igntion system.

Could you have taken it back to the retailer? In UK they would be liable under the Consumer Rights Act, as it clearly should last longer than that. You would be entitled to a repair, replacement or a refund.

Leaving the ignition on while not running will kill the pickups.

If I had bought it locally then probably, but I think I bought it somewhere online, years before the bike was even assembled.
No big deal really, the points have worked flawless since and I have a trigger wheel from Arttu and I have a megasquirt ecu that I'm gonna use as an ignition box along with a vag 4 post coil.

They don't like voltage spikes either

12 years ago, and I live in Australia, bought them from the US of A

 

Not sure if they're the problem

 I tested the pick ups, measured the resistance, put a heat gun on them, all seems to be ok

I hardly do that... Small battery

Never had issues with the 2000 but myself and lots of people I know, have had failed green and grey coils fail shorting down to earth through mounting bar. I had brand spanking new grey coil fail and dyna replaced it straight away, I think they knew they had problem. Now there mini coils are fantastic.

Heat is the biggest enemy of electronics.  I would not leave the ignition on when the bike is not running.  I ran a Dyna system on my Kazio Yoshima 458cc(CB400f) heavily modified) and never had a problem with it.  That bike saw 14,400 rpm's every day, and when I was done, I shut it off.  This was on Kazio Yoshima's person opinion on how to ride that bike.

having said all this, the stock gs and gsx ignition system is pretty bombproof and they arely fail unless theres been a reg rec failure causing elevated charging voltages. so id be tempted to go to the stock ignition system and see how it runs as theyre not  really a known weakess.
