Very interesting the feel in the throttle and frame when accelerating.

Dude! What the heck does THAT mean? Don't keep us hangin'........

First start video after C5 ignition install:

[video]https://youtu.be/dc5pjzXTI9Y[/video]

In the video I used the choke right away out of habit but pushed it off right away.
This morning it started right up no choke.

Now it is very obvious I have carb problems.
Temp gun at exhaust pipe right below the head shows 1, 3 and 4 temps at 450 degrees while #2 at 250 degrees. This is after running for 10-15 minutes in the garage at 90-100 degrees.

The way the bike runs is very different.
1. The idle speed increased from before install without touching anything.
2. I can hold various RPM's above idle steady whereas before rpm would wander up and down and at times drop to idle in a very unstable way. Holding a steady rpm with the throttle was nearly impossible.
3. When accelerating you can very much feel that it's firing on all 4.
The exhaust sounds different, more even and "organized" like it should be. Like a 4 cylinder running.

So far I'm very impressed by the improvements.

I've got some things to sort out before I can do a road test. Maybe tonight.

Sounds good, get that carb problem sorted and she ought to scoot on down the highway. Congrats.

Dan, are you dumping gas on #1 or #3? That sure is more smoke coming out the right exhaust than should be there for running that long in 91 degree ambient temps.

I think I might have a high concentration of ATF at the bottom of the tank.
I'm about to fill it up and go for a test ride.

 

[dan filipi]

Ok this morning after a fill up of fresh gas and a 20 mile ride yesterday there's no smoke out the right pipe so something cleared up.

With that aside, let's get down to the real nitty gritty of this ignition.
Frankly Paul of c5ignitions and Gary at PowerArc can make claims all day long and tell us this kit is doing this and doing that, but the proof is what you see, and feel, and hear.

No bs here guys.
You really do have to experience the difference in person in how the bike feels when you rev it and the change in sounds.
In the video I posted of the first start and run after install, I said to Steve83 the acceleration feel is different. His response was "I didn't feel it before" which is exactly my point here. You have to experience the difference it makes on YOUR bike to really mean something because your familiar with it.

I'm not going to make any claims here that this ignition is a "cure all" for running problems or it's going to provide passing power in 5th gear you didn't have before (though it might I haven't riden enough with it) but I will say and post my real world experiences as I did in the earlier video.

All along my intentions have been to provide apple's to apple's comparison on MY bike.
Mine has carb problems, you can hear it in the video's. I'm certain the #2 carb is flooding that cylinder.
Even with that the idle sped up after install under the same conditions, same outside temperatures, same gas, no other changes but the ignition.
This tells me it made fire where before it was not. I can't say for sure the idle increase is because #2 is firing or I'm getting better burn in the other 3 but the truth is, the idle sped up.

I'm all about pictures and video's to communicate things.

I took this video this morning because I was amazed at the improved spark.
These plugs are a couple old resistor NGK's.
It's running on the 2 right cylinders only.

The camera caught the sparks real well.
The spark is not quite that fat because the video is slightly blurred but it's close to that in person.

Try this same test on your bike. You will see MUCH less spark.
Mine running before with NP08 coils from a 1500 had less than half this much spark, even less with the stock coils.

:shock: HOLY MOLY!! That's a BLUE spark!!!! I ain't never seen anything but a pale yaller spark on mine. That tells me that the ignition is providing a solid fire across the electrodes....it can't help to do anything but fire the mixture! The multi-spark is evident, also. And...running on TWO cylinders? Absolutely incredible..... :clapping: :clapping: :clapping:

Oh..one last test, Dan...reach down there and grab one of them plugs while it's running....let us know how far off the floor it gets you, compared to the stock system.... :hihihi:

 

[C5Performance]

Dan,

Thanks for providing a clear shot of the spark. Running on two? Yes, it sounds like it was struggling but I don't know if my bike would stay running at all with just two cylinders connected.

One thing a video will never show is how it feels when you lug the engine and then try accelerating through it. I'm not suggesting you drag it right down to the point where it starts knocking itself apart, but when you choose not to downshift and the bike accelerates instead of falling all over itself under load.

 

[dan filipi]

One thing I didn't mention is the vacuum advance diaphragm leaked on mine.

2 things changed here with regard to an apple's to apple's comparison which means it's skewed some.

Running on C5 it no longer has a mechanical or vacuum advance.
It also no longer has a vacuum leak on number 3 because the leaking diaphragm is no longer connected.

Stock vacuum advance is made by throttle position, open throttle then vacuum pulls the advance in.
A difference here is the C5 is RPM dependent for the advance. It has nothing to do with throttle position.
I don't know how this affects things exactly but acceleration pull does feel better, mostly above 3000 RPM.

 

[mcgovern61]

I'm gonna try that same spark test on my bike and try to video for comparison to stock. I know mine has run on two cylinders in the past when I was doing diagnostic work on the '81 engine trying to locate the knocking. (Just so we have a near apples to apples comparison to old.) BTW, that is apples, not AApple's! :hihihi:

well sheesh I have to disagee .... you just took all the super advantages that the c5 had and discounted them respectfully .....the whole idea that the motor runs on the condition of the number 3 clylinder exclusively and not the whole motor explanes the huge flaw in the design at its foundation

the whole idea of how everything is lag time on this system in travel response is huge

the instantaneous of the trigger related to speed of light is just undefeatable and really impossible ....but the c5 tech is as good as humanaly possible to match the triggering device so perfectly use as the speed of light ....its absolute no change of command mudded down system of built in lag time and flawed in its foundation of one clylinder command ... witch is toaly why cv carbs are a bad idea thrown into this mix also

so to me the advantage is ... the ignition is totally trigger as soon as gas is burned by the spark plug .....making this totally motor controlled and virtually instantaneous with about as least amount lag time possible .... ok im done

Joe, I think you read something into what I said and need to reread my post.

What I am saying is that ignition advance on stock is governed by throttle position and vacuum present to pull in the advance. Not the case with the C5. It's totally RPM dependent.
Is this better for acceleration or fuel economy? It sure seems so as far as acceleration goes.
Like I said in that post, it does accelerate better now than it did before.

Stock full advance is at about 3500 rpm. That is what my c5 is set at.

When I'm shifting up, this full advance can be felt. I'm just not sure what rpm I'm at which is why I'm looking for a tachometer because I don't have the tach drive on the right head and I'm concidering going back to 1100 cams from these 1200 for a true comparison.

 

[joedrum]

yes I know dan .... apple and oranges comparison is difficult in this this case ....of coruse I relies that the vacume being not tied too vacume advance improved its operation ... so do look at this as nodification to the good that is totally responsible for this to be done with absolutely no down side ... I think its more reason the apple and orange is harder to apply ....

you know me looking at things in strange view :blush: :mrgreen:

 

[joedrum]

:smilie_happy: :smilie_happy: :smilie_happy: sheesh .. I just discovered the rest of your post ....

you know I feel pretty good today but I don't think im with it ..... :smilie_happy: :smilie_happy: :smilie_happy: I think you had it covered dan :thank_you:

 

[dan filipi]

Well I'm also trying to be totally objective here and not sugar coat the C5 and make it out to be more than it is.
Mine not having a working vacuum advance throws me off here some because I didn't feel it with a good advance but I did spend about 8 hours on Dave's 83 recently so I do have other comparison.
Acceleration is better than his was though I'm pretty sure he's got some carb work to do on it.

Like I said before and Paul has said it, you really have to experience the difference in person because the engine just runs differently. With that nice hot spark alone I can see why.

I could not agree more!! I think a Member should step forward with a working vacuum advance!! :whip:

My vacuum advance IS working correctly! No point in sugar coating anything; you will just have to send me your C5 iggy so that we can test it on a fully functional stock system with good working carbs! (Don't worry, I will take good care of it for you.) I wouldn't want all that money to go to waste and get iffy results. (I will get results back to you guys as soon as I can....if you can find me! :smilie_happy: )

Spark test! I did the same test as Dan and I get decent spark, but not as fat as his! But the engine still runs good on two cylinders! :yahoo:

Looks good Gerry!
