I kind of agree with the last two post. I just got done sanding and cleaning the inside of both wheels that were running 'some kind' of tire sealant. After a while the bead gets so clogged up that there is no way it would ever seal. However I do like the Dyna Beads.

 

I used Ride On with my Speed Triple. It was in my last set of tires for over a year and a half. Speeds up to 150mph with no issues. If it did "set up" as one person suggested, I would have been vibrated off my bike way before 150mph. The only puncture protection is the thin strip you ride on. Get it off center and I doubt it will seal. A plug kit for tubeless tires would be in my tool pouch just in case. I'm not sure how well it works in tubes. I'll put some in my 48 when I'm due for tires though.
