I have a Valkyrie Interstate with Motor trike kit but the triple tree is a roadsmith. On a recent trip the triple tree housing failed. The roadsmith tree bolts into a blind hole in the upper tree secured by a grub screw near the bolt head in the lower tree. The bolt had been slowly working out and the lower tree crept down the forks as it loosened so there was no indication of the imminent failure. just a heads up about this setup check the bolt tension!
