Regarding the CDI I have, I read the same thing, so it's fine. I was looking for Ignitech, which is a little cheaper, but it turns out that in my country imports up to $200 are tax-exempt; you only pay for shipping and the product itself. If it costs more than $200, you have to pay an additional 60% in taxes. Regarding the CDI head and curve, I was asking about possible detonation or some other symptom that might not be very positive or beneficial. I was looking at the RSA 125 head design; I didn't expect it to work the same, but at least it seems like a design I could consider reliable or better than the current one. Everything is quite complicated here in Uruguay: resources, possibilities, etc. Perhaps with a test bench or sensors it would be easier, combined with the knowledge acquired over the years. There's a visa I could apply for; it's somewhat expensive, but it allows me to go to the UK to work and travel for two years. Maybe I could try my luck there. There's a lot of desire, but the problem is the resources available here. Thanks @Calum
