Hi folks the gearbox in my 125 2-stroke twin is truly awful to the extent that I suspect there's a selector problem ... It's virtually impossible to get first and regularly jumps out of gear .... The rest of the motor is great so I wanted to pull it out and play over the winter but drop another unit in so I can keep riding ... Anyone got a good 125 twin engine they are selling must be a good runner with of course a good box? Happy to collect, I'm in the Midlands thanks Si
