Posted: Thu Jun 19, 2008 10:02 pm Post subject: Tri-Spark Classic Twin |
|
|
Hi Guys - you may recall that Steve Kelly announced his new Tri-Spark 'Classic-Twin electronic ignition system for Norton,BSA and Triumph Twins. I fitted the system to my 920 Commando yesterday. The installation was very simple and it started first kick !!!. Running and idling are brilliant. I timed it to 28 BTDC and I may experiment with this at a later date but I'm tempted to leave well-alone. The 'anti-kickback' system is great - the bike always tended to kick-back if I was a bit 'half-hearted' when kickstarting but with the new system there is no sign of this behaviour.
I would recommend this kit to anybody.
Cheers, |

| Hey Mark do you know if this system can be used with a single fire Dyna coil? And if so what ohm is the best? I just got mine in the mail today and it has no info on this, Or if anyone else could help that would be great, Thanks, Chuck. I sent an e-mail asking but thought I would try here too. |

Hi Chuck
Steve will get back to you about the coil. I asked him for modern alternative coils for my triple last year & he was already working on it.
all the best Chris |

Hi Chuck,
You can use 2 Lucas type 6 volt coils or one dual output coil. The primary resitance of the dual output coil should be between 3 and 5 Ohms.
I did an installation on a '73 madel last weekend and that worked fine using the stock coils. The istallation was easy and with minimal changes to the wiring. I wrote up an instruction sheet on what we did to go out with the noton kits.
cheers,
Steve |

Steve,
So the Classic Twin is not a sequential firing type like your other systems then? |

| Mike, where in the USA are you getting the Pazon these days? Are they currently going for the price that you got it? |

Mark, I may have missed it in an earlier post but what are you comparing with ? If your old system was points then I'd expect an improvement but if you already had electronic then I want a Tri-Spark too !
Get out there and cover some hard miles ! I hope that the assembly will prove to be robust sitting there but I slightly share the reservations which L.A.B. voiced a while ago. Bearing in mind how we used to go to great lengths to rubber mount RITA or Boyer boxes, it concerns me a little to think about what's going on down there behind the cover ! |

I got it from MAP cycles in florida - think it was $159 - got it about 3 months ago and am very happy with it - bike runs much better than it did with the boyer, which i replaced when it failed (only lasted 20 yrs!). Hopefully the pazon will last as long! |

The Unapproachable Norton Commando
At the end of 1967 the Norton Commando was announced.
The Norton Commando was greeted with a certain amount of scepticism because on first sight the commando appeared to comprise of the old Norton Dominator twin cylinder engine mounted at an inclined angle in a set of new cylinder parts.
It was not realized that the new Norton Commando Isolastic method of engine suspension damped out all engine vibration and produced a machine which had uncanny smoothness for a vertical twin. In due course the critics were silenced and the Norton Commando had the distinction of being regarded as the first of todays so called superbikes. There can be little doubt that the original design concept of the Norton Commando has proved correct, since comparatively few modifications of any real consequence have been made since production commenced during 1968.
Now nearly 40 years later Norton Commando riders like us are a breed of our own, and as far as we are concerned its still more fun to go for a blat on the old Norton Commando, and fast. As a Norton Commando owner and enthusiast, my goal here is to promote and give credit to those who keep the Norton name going.
It is more deserving to give credit to the Commando itself, for after all these years it continues to be respected. The original Commando designers like John Favill are those who deserve the credit for developing this incredible motorcycle.
The Norton Commando Roadster and Interstate of the late seventies, never died. Although the Norton Villiers factory dispersed the tradition lived on. Today Kenny Dreer in the USA is developing the new 952 CC Norton. What a great looking bike this is, and its engineering is still based on the original layout. It will be interesting to see how the new 952CC Norton does in todays tough motorcycle market. One thing is for sure, I would own one if I could afford it.
