hv1300

Looking for some advice please. I've striped my daughters txt125 07 engine to replace all the bearings, I've come to close casing up but as soon as I get them approximately 5mm or less from closed together the gearbox locks up, I've been through the gearbox diagrams multiple times and everything look right and turns freely prior to that last few mm. The only thing that looks odd to me is the way the clutch shaft butt's up against the casing needle bearing without a washer, up there wasn't one in there and there's non in the diagrams, any advice would be appreciated.

Can any one advise me on what wire to interupt with a magnetic lanyard on a tw200, I'm assuming it's one going to the starter/kill switch on the bars. Bike is a 2021/22. Thanks
