Someone else must have figured this out. If you need to change gearing often you can't be using the clunky (expensive) single use Yamaha OEM front sprocket nuts.  So what is everyone using and where do I get it? It would be nice to be able to change gearing more than once at Summit Point in a couple of weeks.

Reuse the same nut, but don't fold in the to lock it.

Options for keeping it in place; silicon or safety wire.

I considered locktite and silicone but it seems a bit iffy. I didn't mention, in my case the chain runs between my legs so I REALLY don't want it deviating from it's intended path. Lock wiring would require drilling the sprocket shaft which looks very HARD (in a least 2 senses of the word).

I would use the stock retainer and fold it. Just chalk it up to being safe. I had a drive sprocket come loose and lock up at motor cross track. Put me on the ground hard could have been deadly. All because I didn’t use lock tite. Do yourself a favor and be safe
