I finally picked up my Rancher today, new tires and all. Feels great to not be the guy on the back of another guys atv. Its been at a shop since december, they finally fixed it after the 3 year hassle. Whats got me concerned is the top speed, being 38 mph it seems low for a 420cc machine. Its like im missing a gear. Up to about 30 mph the motor sounds good and deep, but the throttle is only about half way down. When i run it full throttle it only gains a few mph but sounds whiney and rattles alot. Like its reving up to high. I can deal with that slow speed but is it harmfull to run it full throttle? It sounds terrible when I do.
