OK, so I just got all the parts for Matt's throttle from his recumbent build. But before I get started I was wondering if somebody knows how to use a three wire throttle such as a magura instead of the knob he uses. Or at least, the additional parts I need would be nice, any help will be appreciated though. Don't get me wrong, Matt's would be ideal for putting down some miles (or km), but for dirt action I think a thumb or twist throttle would be better.
