rad. coolant recovery modifacation...How Good?

[dell30rb]

Has anyone else seen those bottles you mount to the rear of your number plate that take the coolant when the rad. boils over and then gives it back to the rad. when it cools down?

I heard that the gas gas bikes have them stock. This system is on sale at denniskirk and I want to know how good a job it does and if its worth the 16 bucks?

Thanks

depends on the kind of riding you do, if you're in the woods alot where the bike gets hot but then cools down afterwards then they're great. I personally think they're great anytime, because coolant is something that most people don't think to check on. So if you've got a bike that doesn't have an overflow it's well worth the $16 IMO.
