Need Troubleshooting Help - Carbs, Timing?

[BPT]

Thanks MrClubike, I'll see about getting such a thing.  As far as the valves, do you think it would start and run OK at first, them go bad after a few minutes?

And thanks Justin, that was next on my list.  Unfortunately, there will be no riding.  The last try I couldn't get out of the driveway.  But I'll crank it up and let it run until it does that again and check the bowls as you said.
  What should I look for if the bowls are dry?

Update: had a little bit of time to fiddle with it. Of course, it didn't want to replicate the problem exactly.

It starts up with no problem. I let it run a few minutes then took a spin around the block.  It sounded a little bit rougher but not much (and I had been tinkering with the carb idle mixture before so I'm sure it's off now).

I went home to put on shoes again and take a longer ride. I've noticed now that in 2 & 3 gears, when I rev to about 3000 rpm, it starts to sputter.

MrClubike - haven't gotten any kind of tool yet but I did use the short-on-the-cylinder method and looks like I'm getting decent spark from both plugs.  I pulled the tank and did see anything loose or melted as far as connections go.

Talked to my local shop guy, without seeing it, he's leaning towards ignition, probably something with the bean can.  Waiting on it to cool down right now before I inspect that.

Any more thoughts?

For coils, I have the dual (one piece with two outlets). Appears to be grayish but also dirty. Is any gray coil one of the possibly bad ones?  Or was it just a certain run of them?

Any ideas are helpful. As it stands, I can't ride it to my local shop do will be slowly trying to eliminate things in the driveway.

       Thanks again.

The black and gray coil is a problematic part .

If you can get a good look at the coil with the fuel tank off, check for cracks in the case where the steel laminate core goes into the coil .

I've noticed now that in 2 & 3 gears, when I rev to about 3000 rpm, it starts to sputter.

I had a pin hole in the carb diaphragm that acted like that. Idled like a champ but would not rev........ depending on the size of the hole the symptoms would vary I should think.

[mrclubike]

Can you show us a picture of your coil
If it is the original one I would change it

[BPT]

I can do better than that Bob Roller, I've got it right here in front of me.  According to the internet and the part number, this is one of the bad ones.  Not sure exactly where you're saying to look but I think I'm seeing cracks on the end opposite of where the wires plug in.  Here's a pic, not sure if it will be clear enough to see.
So I'm assuming this should be replaced regardless of whether it's the source of my current problem, right?  I'm a little confused on how to determine which replacement to go with.  I figured the Dyna but which color? The orange?

[BPT]

Thanks Wilcom, I'll put that in the memory bank. I have no idea when these carbs would have last been rebuilt. I was hoping I could put that off for a while.......

[BPT]

And MrClubike, I guess we were posting at the same time. Here's a pic of the coil, pretty sure it's the bad one.
I was confused abut the gray vs. black since this has a little of both. But going by the number and riveted bracket, I think it's original.  Seems like I saw that the replacements for the bad ones were made in Slovenia. Mine's a German.......

You have the "Crackomatic" coil and on the end pic you can see the cracks starting.  Mine was very obvious and bike wouldn't even try starting.

[BPT]

Yep, so it needs to go. So what is the proper replacement?

[BPT]

I guess our messages are crossing also, Justin.  From what I'd read, it seemed like the orange was what I needed, but I wasn't 100% positive.

And I'm assuming it's going to be via online. You don't know anyone in the metroplex that carries such a thing, do you?

[Justin B.]

No.  You can get pretty quick service from Euro Motoeoectrics.  I ordered mine from mpsracing.com and checking my receipt it is the "brown" coil.

Here's two links to online suppliers that carry the Dyna ' brown ' coil .

http://motoelekt.com/ignition.htm

http://www.euromotoelectrics.com/product-p/dyna-coildc2-1x1.htm

Both are great businesses to do business with .

I think with Euromoto Electrics, you have to purchase the mounting adapter seperatly, Mororrad Elektrik, the adapter comes with the coil .

If the ignition leads look like they might be on the old side, both of these sites, have ignition leads as well .

[mrclubike]

Yep the Brown is the One you should get
And I also second the opinion you should replace the wires and caps
5000ohm caps and copper core wires

I think Ricks (Motorad Ele) bracket is better than EME

I've used both of those places, good folks at both. I was going to check on prices and shipping and go from there. And where we sit in the US, probably the same time wise from either.

I also have the original ICU. Since nobody's mentioned that, is it safe to say there's no need to mess with that if getting a new coil?  I saw that the Beemershop has an Emerald Isle version for $30, but the other places get  more spendy.
