I have a Pazon Smart Fire on my 1972 Norton 750 Combat engine. I find that turning the ignition Off and ON between kicks eliminates the kick backs. Has anyone else had this experience ? The battery is good so that is not the issue
 
Norton#72,
I have the same unit as you and i noticed that as well. However it usually starts on the first kick so it doesn't seem to matter. Since it's a wasted spark ignition it fires after the first pulse it receives anyway.
I have a '71 using the Pazon and a two plug coil. Are you bringing the engine up to compression before you kick? Is your timing set to 28° btc. One thing about Nortons, we have to commit and follow through when we kick these things, otherwise they will hurt you! ;-)
 
I have one on my 650SS, what I have found to be first kick each start each time, is to leave the key turned off, bring up to TDC, turn key on and a good committed follow through kick as mentioned above.
If I turn the key on and try to bring up on compression, you can bet your life you are going to get one hell of a kick back:oops:.
Yes timing is correct.

The Pazon Surefire analogue, in common with all the other analogue EI's, has a sleep feature whereby after a few seconds on and not receiving signals from the stator it shuts down. Where it differs from the other EI's is how it wakes up, Boyer awakes after one signal pulse, the Pazon wakes up after it receives 2 signals close together enough to show the engine speed is at least 100 or maybe 200 rpm (the details are on their website). So a Pazon surefire that goes to sleep has more likelyhood of kicking back than a Boyer as the crank has to travel 180 degrees more before it wakes, by that time the crank is slowing down.

I found this out on a B50, owner could not kick it to start but it would if bump started, he asked my to troubleshoot and I found ref to the sleep function and wake up requirements in the instructions and tried the quick ignition off and on which did work. When he got in touch with Pazon they made a version that took longer to go to sleep and now they warn you not to use the Surefire on high compression big singles.

Turning the ignition off and then on before kicking also wakes the box, as long as you kick within the few seconds time window then you will get sparks the first time it gets a signal.

Their fully digital version may be different but is it is the same then that fits the symptoms.

Yes, I was referring to the Surefire thinking the Altair was there only digital version, Smart fire is also digital. Edited post to clear up the surefire has the sleep function.

The digital versions also sleep, its the wake up routine you need to investigate. The pazon site is silent on the wake up routine.
 
Pure analog is long dwell, high resistance coils
There is long dwell, digital higher resistance coils.
There is short dwell, digital low ohms coils

It is a shame that the mumbo jumbo marketing names become a hide behind screen for their operation modes. Which of these modes am I buying is what "I" would want to know.

Yup, same on Altair. Crappy design. Never again.
 
Can the Smart Fire be run with two six volt coils instead of the PVL dual outlet that comes with the kit ?
 
Thanks Les.
I will have to machine a mount for the coil at the front location (There were reports of the PVL coils failing on BritBike.com (John Healy) and mount the control unit back near the battery perhaps so they are separated, the three phase R/R moved away from it ?

There is also the 5k Ohm caps that come with the HT leads which will not help having Denso resistor spark plugs.

No need for resistor caps if you use resistor plugs and the ones supplied look like the normal NGK screw-on (LB05F) type.
 
Exactly, Pazon supply those 5000 Ohm resistor caps in all the ignition kits I have bought but not much use if using resistor spark plugs and am willing to bet there are bikes out there with both resistor plugs and caps.


It has been discussed before.

"Since resistor type plugs actually “resist” some of the spark energy, non-resistor type plugs actually deliver a more powerful spark. ... Use of non-resistor plugs in vehicles that call for a resistor type can result in rough idling, high-rpm misfire, and abnormal combustion."

A Commando would be somewhat different to needs compared to a car with multiple electronic devices.
Maybe I will have to get non resistor spark plugs as the easier option or get these.


I prefer everything but electrical. :eek:

I bought these, but alas out of stock here :-(
