Bern, The 4 speeds aren't the best transmission but they were simple and reliable.
This guy's plight is just one reason to not want one. If it was a failed clutch on a crash box it is a big job to do the split/replace but new parts are readily available for $150 or so.
To do this job on his SOS is a bigger job with a double split and he's forced to find used parts for a lot more money.
And then there's the issue of their
complexity. Add to that their lack of precision for tight manuvering and their very unpleasant hard shifting I really don't know why anybody would want one.
Mark,
Lol,
I was a little hard in them in that ad wasn't I.
