      I’ve acquired 2 of these, nearly complete, good bores by appearance. Were these “common” kart engines at any point? Mine came with a microsprint, but I think I may throw one on a kart to have fun at the local sprint track which has an “open shifter” class, and perhaps WKA long-track events… Anyone help clue me in? Thanks… ~Ted

      It was never that common but used sparingly in Europe and North America in FC. From what I recall the biggest gains we made with the stock engines was by cutting a few rotary valves as from stock they do not have enough duration.

      Pipe technology has come a way as well. And you can make gains trying some pipes.

      The ignition was very good for it’s era and the case/cylinder design. You may be able to bolt on a new era BRC cylinder for more juice.

      Neat cassette style transmission and light design.

      Enjoy your engines!

      Joey, I appreciate your response, but we must be talking about two different engines — mine are reeds?

      The engines I have seem to be the same as featured on the 1988 Aprilia Tuareg.

      LOL @ Riley — no worries — they were “free” From the specs I read, basically 30hp…. What about throwing a DD2 cylinder on there, or a Polini 154 or whatever it is?
