Please forgive me, I know this is a question I've placed in the wrong forum, if You need to remove. I understand. I've never had the clutch (right) side off my DT-250, but my RD 400 is having issues, so im getting familiar with it. Figuring most Yamaha 2 strokes are similar Just needing to know if there is a way to install a replacement kick axle gear assembly w/o removing clutch/basket ? Kinda goofy, the old one goes in...? I watched a YouTube where the guy does install without clutch removed. Made it look way easy....mine not so much..thank You folks.

I've been there but was a lifetime ago. If you mean the gear on the kick shaft then yes that shaft should come out without clutch off. If you mean the intermediate gear then clutch needs to come off. Be unusual for a kick gear to fail without other issues being involved?. When refitting the shaft assembly be sure to engage the friction clip in its guiding slot as tensions the gear which causes it to engage when ever kicked down. Cheers from NZ.
