You mght try Motion Pro. They are more dirt oriented but may be able to fix you up. I have a 1/4 CR250 MX throttle on my Raptor and I know Motion Pro makes a good product.
For the benefit of nemethjames1, a 1/4 throttle enables a rider to go from closed to wide open in 1/4 turn. All MX dirt bikes and many sport quads have them.
