Mike,It will be a good while before I'm finished with them.I'm thinking when the temps cool down a little I might give it a try and see what happens.I'm in no shape to ride at this point,so I'll be taking my time........I bought two,so I just happen to have a spare.That will piss Mark Cody off real bad when his wimpy little 450 gets spanked by a pair of screamin' 125's!
