Lower priced, possible replacement for C5 ignition system.

[chilidawg]

Have any of you guys ever seen or tried this?

Is it not what it purports to be? Is it trash? is it new? I really don't know, but....

What I really want to know is, will it work on my 1100 with a '75 cam as well as a C5 will??? :idea:

Thats an electronic ignition, C5 is optical, The Dyna uses a magetic pulse to fire the coil the C5 used a light beam/sensor. From the feedback I have heard the C5 is the one to get, Guys have removed their Dyna`s and replaced them with C5`s have been even more happy.

You don't always get what you pay for. And almost never get more than you pay for. As stated above and in the ad you linked. The Dyna is an electronic replacement for the points ignition. Performance wise if the points are new and set perfectly. I doubt there'd be a noticeable improvement with Dyna. The C5 however will give you noticeable difference over any previous ignition for the better. Noticeable in starting, sound at idle, throttle response and torque. Dyna is a good company with good customer support. It is a good ignition but does not compare to the C5.

Okay I get it, it will be just as good as my existing GL1100 ignition and I'm teaching my grandmother to suck eggs.

I was just putting out there 'cos it was new to me!

Dyna ignitions have been around a very long time and have outlasted Martek and Gerex ignitions.

c5 is much better..... it lights yrs ahead of the dyna system ....its over 300$ for there sytem too once coils are bought that match it plus wires....like the c5 has in it system that is priced total always .... the dyna sys has way less than 1/2 the capabilities as c5 has ....

A more fitting title for this thread would be Lower priced, possible replacement for 1100 ignition system because the Dyna system doesn't even compare to the C5.
Dyna compares to points or a standard electronic ignition.

A Dyna will get you a spark at all 4 plugs, just like the stock ignition does.
It will also give you a magnetic pickup just like the electronic pickup that varies.

The C5 comes with it's own coils, optical pickup that does not vary, and 3 FULL sparks per ignition cycle.
There are other threads about magnetic pickup versus optical pickup for some good reading.

Ok, I'm real interested in the cam change to 1000 cams on my 1100. You guys need to sell this to me, I would like to know about the power and fuel mileage changes you are seeing.

I've seen you talking about it. Next week I'll be picking up another 1100 and it is a beauty for a 1983 bike, well cared for. Pictures to follow. I'm going to rescue it from my salvage yard friends

A few weeks ago I bought a 1200 but it had been butchered, all the plastic was off the biike and busted all up. Will need to trade it, I'm thinking and so does my wife. I have spun the engine over and it sounds as if it had decent compression. It had 53k on the clock. The 1100 I'm most likely to pick up next week has even less miles on it. 30k something I think, and it had to have spent most of it's life in a garage, even has decent rubber on it! Radio is still on it! Rare find, certainly is for the price I'm gonna pay!

If I was to keep the 1200, was interested in some parts changeover for my 1100, but in looking at that there is not a lot, other than the engine that I could use, cause I was looking at changing the front end, but not sure how that would work out.

I only have experience running the 75-77 cams, 1100 cams, and 1200 cams in my 1100.

I find the early cams are great for improved performance above 5000 rpm. Lower seems to suffer some.
1200 cams improved lower end torque, higher rpm it suffered.
These are compared to the stock 1100 cams which I feel are a good all around match for the 1100.

 

[chilidawg]

I'm with Dan on this, the 77's I have on now make a nice difference at 5K and above.

But if you don't usually do that kind of thing, it ain't worth it.

The perfect condition, 75's are at this time wrapped in grease tape and stored in large zip-lock bags until next winter and will most likely now be accompanied by a C5 ignition .

As for fuel mileage, I don't know, I single carbed mine and rebuilt the heads at the same time I did the camshafts, but my fuel consumption is better.

 

[joedrum]

I feel there is absolutely no comparison at all ive tried them all on very good running bike except 1200 cams ... there no doubt in my mind that the 1100 loves the early cams ...and I experience no drop in torqe at lower rpm and got a huge rpm sweet spot ... the angry dresser is a well running bike with early cams and early carb rack too ... I am fixing to go single now on it though as I like the weber carb set up better than stock .... I would never go back to 1100 cams or any others ... I think the early 371 cams yr 75-77 1000s work better in 1100s than the 1000 in my opinion

 

[dan filipi]

In trying the different cams my test is very thorough with the same street and freeway run where I can feel subtle differences and in the throttle positions.
On one specific grade running the 1200 cams, it accelerates better from 55 to 70 than the 1000 cams but downshift to 4th to get the R's up and the 1000 cams come alive.
Just depends on how you ride.
I like lower end torque which is one reason I put the 1200 engine in.

Now with Joe's 1200 running 1100 heads, early 1000 cams, freer flow exhaust and lower gearing, all bets are off.

 

[Riding a Relic]

Yeah, joedrum posts is what made me jump on that 1200. Since it was a good deal made it better. Now, I don't know if the transmission in the 1984 1200 is any better than what I have in my 1100. Do you guys know?

 

[dan filipi]

The gear ratios are taller than your 80.
With your 17" rear wheel you might love it, might hate it. I found with the 17" and 83 gears the gearing was too tall which sucked too much engine power and in twisties with varying grades up hill the ratios didn't come in at the right place.
Level cruising was nice though.
1200 with more power might be good.

 

[joedrum]

nuch better gearing in 1200 84 yr ...its the same inside motor as 83-1100 ... it has the widest spread of gearing in transmission ... to me either 1100 and super more so in 1200 .. the gearing is great ...good motor will handle the gearing well ... the 80 gearing is very close raitio gearing ... but we are not talking huge difference in rpm unless you are talking 70+ and more all day running like touring

:0fftopic:

Hmmm.......I think you guys might need to go over to the 1200 cam threads....This topic is about the Dyna or C5 ignition discussion!

 

[Riding a Relic]

Ok, but might wind up trading this 1200 on a 1983 1100 if I can.

 

[slabghost]

I'd hang on to that 1200 motor at least. And if the 1200 is going to the scrap yard could I get the removable frame section from it first?

 

[Riding a Relic]

slabghost, I already talked to the salvage yard about the bike I'm trading. They want to see it of course, if I wind up scraping it myself, I'd be happy to let you have it. They have all that stuff and sell it at willies cycles in camp hill, al. They won't rip you either. They have a website, but not a super good site. They have been in business a long time and sell to bike shops all over the world. About all they deal with is meteric bikes, and are very knowledgeable about most power sports stuff. They do 4 wheelers, too. Some water sports stuff also. They sell on ebay, too. Call them up, whatever you need, they most likely have.

Why would you need a frame section?

 

[slabghost]

My frame section was damaged by a PO in an accident. I am trying to eliminate all damaged parts.
Got a phone number for these folks? :thanks:
