I want to gear my yz426 down just a little bit. I don’t need anymore low end power, I just want to be able to ride trails in 1st and 2nd gear at a little slower speed. I have the factory sized 49 tooth rear sprocket and was wonder if going up +1 or +2 in the rear would make a noticeable difference? It's time to replace my chain and sprockets anyhow so now would be the time to change the gearing. Any suggestions will be much appreciated!
