JAWA 2 stroke power tuning (part 6) how to make motorcycle gears

Content, brand new content Yes, it has been a while. It just took me 1. 5 years of (re)search, development und finally production of just a hand full of gears some might say. But you better check everything twice if your own life depends on what you make. This is the story of finally getting rid of one bigger blind spot on my JAWA 350 power experiment. The old gearbox that just stayed alive under the enormus load of a 47 Nm 2stroke thumper. But with heavy pitting and as it turned out a bend main shaft. This should now be over. Thanks to some historic JAWA MX competition parts. But mainly thanks to the grateful help of two Czech Specialists from who live their passion and convert it into reliable gearbox parts, which are better than the historic originals in most cases. Enjoy this piece of workshop insight and as always, thanks for your comments.
