Claim 13

In combination, a base over which the mid-portion of a motorcycle may be positioned, said base including horizontally spaced apart anchor points and elevatable jack means generally centrally intermediate said anchor points and upwardly movable relative to said base to engage and lift the forward lower frame members of a motorcycle disposed thereabove, and a pair of upstanding elongated adjustable length bracing rods having their lower ends anchored to said anchor points for at least limited universal angular displacement of said rods relative to said base, the upper ends of said rods including anchor means for releasable rigid anchoring to the end portions of the handle bar of said motorcycle, a movement dampening structure for disposition between a lower portion of one side of the front fork assembly of said motorcycle and the vertically reciprocal pickup rod of a strobe light actuator for a wheel spin balancing assembly, said movement dampening structure comprising an upstanding motion transmitting structure including relatively extendable and retractable elongated upper and lower end portions guidingly supported from each other for lengthwise extension and retraction, means carried by the lower and upper ends of said lower and upper end portions, respectively, for releasable attachment to said pickup rod and lower front fork portion, and opposing and balanced compression and expansion coil springs connected between said upper and lower ends yieldingly biasing the latter toward predetermined relatively extended positions.

Claim 14

In combination, a base over which the mid-portion of a motorcycle may be positioned, said base including horizontally spaced apart anchor points and elevatable jack means generally centrally intermediate said anchor points and upwardly movable relative to said base to engage and lift the forward lower frame members of a motorcycle disposed thereabove, and a pair of upstanding elongated adjustable length bracing rods having their lower ends anchored to said anchor points for at least limited universal angular displacement of said rods relative to said base, the upper ends of said rods including anchor means for releasable rigid anchoring to the end portions of the handle bar of said motorcycle, a movement dampening structure for disposition between a lower portion of one side of the front fork assembly of said motorcycle and the vertically reciprocal pickup rod of a strobe light actuator for a wheel spin balancing assembly, said movement dampening structure comprising an upstanding motion transmitting structure including relatively extendable and retractable elongated upper and lower end portions guidingly supported from each other for lengthwise extension and retraction, means carried by the lower and upper ends of said lower and upper end portions, respectively, for releasable attachment to said pickup rod and lower front fork portion, and opposing and balanced compression and expansion coil springs connected between said upper and lower ends yieldingly biasing the latter toward predetermined relatively extended positions.

Claim 15

A mounting bracket for attachment of a strobe light actuator pickup rod to one side lower portion of a motorcycle front fork assembly, said bracket including an arched plate portion including a centrally notched longitudinal side edge portion, the opposite ends of said notched edge portion having mounting apertures formed therethrough, the opposite longitudinal side edge portion of said plate portion including an elongated generally planar flange extending along said opposite longitudinal side edge portion angulated slightly outwardly of the convex side of said plate portion, said planar flange including a pair of depending parallel flanges extending longitudinally therealong, said flange portion being constructed of ferrous material and the spacing between said flanges being adapted to snugly receive the free end portions of an inverted U-shaped permanent magnet therebetween.
