Hey,
As part of the Tri Spark Team (since I do sell them) it appears that I am due to answer a couple of questions. Just to make sure you understand, I only sell these units. I dont have anything to do with the development even though I am absolutely certain that Steve Kelly would listen and make changes if I had some serious concerns about his product. Its most important to him to offer a product that works for our customers out there.
I, since starting to offer the Tri Spark 2 years ago, have sold 195 of them. I have during this time replaced 5 units that customers had problems with. 2 of those units, when I got them back to the shop, were installed in bikes here and worked without any issues whatsoever ( and are still running as we speak). The replacement units for those 2 worked trouble free for the customers, so what the problem was there, I am not sure. I have no equipment in the shop to test any of the Tri Spark parts. I just send them back to Steve Kelly so that he can check them out to determine what may have been wrong.
So with that said. 3 (1.5%) failed units out of 195 sold. I do not consider this an alarming amount of units at all. Answer to question #1...... No.
I can not answer the second question since I dont do any testing in house.
I also want to mention, and this is obvious to those that have dealt with CNW over the years, that if I had any reservations or thought this ignition was in fact plagued with issues, I would most definitely not offer it any longer. It would not be worth selling them if my reputation for offering products that are of great quality, was at stake. I have nothing invested with Tri Spark other than selling their product.
Also understand that nobody is getting rich selling these units. Sure we are in the business to be profitable, but with the AU $ exchange right now, most retailers wouldnt even consider offer these units at the available margins.
I had the pleasure of meeting Steve Kelly last year since he stopped by my shop while visiting the US. He is a top notch guy that is doing something that he is very passionate about. If he was just in it to make a buck, with his electronic knowledge and ability, I am sure that he wouldnt bother with making parts for Vintage Motorcycles.
As far as the vented ignition cover, this is something I decided to move forward on (no input from Steve Kelly) myself since I wanted to CNC some billet ignition covers anyway due to the poor quality of "new" ones available. It was of some concern to some people that the cavity was to hot and I though that this would easy their mind. I am not saying that one of these covers are needed to when using a Tri Spark ignition. Just an option if somebody feels like it would be better and besides the finish is really nice, so it makes that part of the timing cover look much better.
....and to wrap it up........'Commando 75', you should not have any issues with the Choppers any longer as I aborted their mission this morning. I sent them in a different direction ! (you would never guess where....)
