I have a 01 yz80 I did a big wheel conversion on and now my bike has no low end power and has trouble making it up steep hills when riding trails before bike wheeled when hit power band and pretty much all the time so I don't want it to wheelie as much as before I just don't want to waste money on a million sprockets. What sprockets should I get I have a pipe and some work done basically only thing not done is a big bore kit
