Hay guys what's up. Here's the deal In the last six months I've stripped out 3rd gear on my yz 450 and 250 2 stroke transmissions. I've been riding racing over 15 years. Im a A rider and have never had these issues before. Someone at the track I was talking to was saying I may be riding the shifter without knowing it. I'm meticulous about my maintenance so I know it's not related to that. The only thing is sometimes I do shift down at the end of a long moto without the clutch all the way in I suppose. Who doesn't right ? I rode Hondas for 7 years and no transmission problems. I do run 80w tranny oil ether bel-Ray gear saver or pro Honda 80w red bottle. And always put a tad more than manual says. Is there any coatings or chrome that can be done the make the gears stronger. What do the factory's do ? Can something be done here on am I just to hard on the transmission ?
