  1. I emailed Jitsie, and they responded that they hadn't had any problems with those springs. They asked me what year the bike was, and in the end, they brushed it aside, saying the spring wasn't suitable for my bike's year. I'm an amateur mechanic, and what I really enjoy is engine tuning. Back in the 1980s, I'd already tuned Vespa engines for racing, Puch Minicross engines with adapted Derbi cylinders, Puch Cobras manufacturing 6-stroke transfer cylinders... I have books from mechanical engineers on 2-stroke engine tuning, and also some MS-2 software for calculating reed valves, transfer case openings, and RPM, as well as calculations to determine carburetor diameters and some exhaust pipes, among others. What I mean by this is that I consider myself to have a minimum of mechanical knowledge, and I believe I know how to calculate BHP or RPM of an engine using mathematical formulas. I think that when I get a spring that they say is a clone of the original and it turns out the measurements don't match, I think I know how to perform the analysis and measurements to determine if it's good or not. You just have to look at the photos where it's clearly evident that they are not the same. I ordered the spring from a prestigious specialty store (they sponsor a private pilot in the World Championship), and they told me they didn't sell that spring because it didn't work. They sold the original. That's why I decided to order it directly from Jitsie. What I mean by this is that I don't like being treated like an idiot, and that my intention at all times is to give them information about the product they're selling, and that it's not what they say it is.
  2. The problem I've encountered is that the spring is not the same size as the original, it has longer pins and a different angle and it doesn't fit into the tensioner arm anchor. I've sent them an email with photos and they tell me they've never had that problem since it's a clone. ALSO THEY SAY IT'S STAINLESS STEEL AND IT'S NOT BECAUSE IT'S MAGNETIC AND STAINLESS STEEL IS NOT. (There are some stainless steel ones that have a slight amount of iron and are slightly magnetic but this isn't the case since iron is very attracted to iron. (I have the emails sent and their responses, as well as a video showing the spring's magnetism that I can't upload. Can you tell me how to upload videos?) Email Jitsie muelle ingles.pdf
