I am trying to put together a whole dirt wheel setup for the DRZ, and I just bought a set of wheels and tires from a DRZ E (mine is an SM).
I know I will need new rotors for the new wheels, because the SM rotors are considerably larger, and the caliper brackets dont line up. And I dont feel like changing brackets around every time I want to switch from dirt to street.
I also think I'm going to need two chains. The sprocket on the new wheels I bought is HUGE. This is good, because I want low gears for the dirt riding. But, my chain is not going to fit.
How do I know what size chain to get? Can you count the teeth on the sprocket and guess from that? Or is there some standard size that you use, and just add links as necessary?
Sorry for my ignorance, I have never messed with a chain before.
