Gotcha on the Gill. Thought you might be referring to another aftermarket product. I always refer to that as OEM. I've got 34kmiles on my bike with no issues with the OEM CDI. I've been running Nology hot coils and wires for over 20Kmiles with no issues. The first Procom I got ran good at first but was hard to start without boosting the batt. Of course that was back in January and pretty cold even for the south. Otherwise, once going it did great. I was amazed at the difference in performance even with stock pipes and carb configuration. I'm running open pipes now with 126 jets in my carbs. Speedmaster 865 carbs on an America 790. Does good but that Procom unit makes her run like a red ape. Sure would like to get one that would work right. Don't like pulling the tank every time I turn around either. The replacement unit that Procom sent looks shotty in its assembly. The pins where the wiring harness connects are all out of line and the plastic shell is uneven across the back edge where the Scotch Cast is poured in. I think they must have good design and circuitry but the manugacture process lacks quality control. I've not abandoned the idea yet. I'll check some things like voltage and so forth, and see what I can figure out. I was wondering what dial setting the other 270 degree engines were using. Mine is set to 5 for my OEM part number but I'm wondering what makes the difference? What settinga are the other Speedmaster and America riders using? What is different electrically on the Speedmasters and Americas that causes Triumph to use different CDIs on the different models. I know the 790s have different cams and there are slight differences with the carb configurations but what about the electrics related to the ignition system? I just don't see that there is that much difference in the actual parts. Timing/maps yes but the parts like coils, wires, pickups, fps etc. Just don't see a difference. What do you guys think?
