Hi guys
So I went ahead and bought the stoltech revalve package and linear spring install. It didn't come with instructions, but I went ahead and got this done at the local yamaha shop.
We disassembled the inner chambers and loosened the nuts. As the nuts came off, a part of the peening broke. But we changed the valves and screwed the nut back on with red locktite. Seemingly, enough thread was still available and we didn't think much of it.
First ride seemed very smooth. Until I jumped the bike off a small obstacle... I heard an immediate clunk as I left the ground (ie. as the fork extended fully), I could also feel it in the handlebars. Later I popped a small wheelie and could once again feel the obvious clunk. See video: https://drive.google.com/file/d/1spm2QuZGocYZqirrly86hsufx5KFxAUn/view?usp=sharing
I started googling and realized that some other people have had similar symptoms from the nuts unscrewing themselves from the stems and exploding all ove the inner chambers. Reading this made me really worried. I just think it's strange how it would unscrew itself, if so is the case, so quickly, after like 30 minutes of riding.
How screwed am I? It will cost me more than a grand to buy new piston kits and new stoltech valve kits.
