Hi there I am new to the fourm and am wanting to see is someone can help me fix my speedometer some of the numbers at not showing up anymore. 

I would bet the rear axle carrier bearings are bad. Put the quad up on a jack stand and grab the rear tire and see if it has alot of up and down play.

I never knew what a spad was , had to search it up   

Can anyone tell me what the shift gear position sensor does on a Honda 450s Forman? Does it tell you what gear you are in. I only know when I am in neutral (green light) or reverse (red light). When I assemble the rear housing does it matter what way the shift gear sensor pin goes into the pocket of the motor housing.  I know the sensor pin has been rotated so maybe the timing could be off. I hope I am making sense. Thanks
