I will be replacing the sprockets and chain on my DRZ, finally getting rid of the stock parts. Anyway, my question is about gear ratio. Up to this point I have had no complaints about the stock gearing. Background - I will be doing primarily woods riding, in Indiana (not to hilly), and I may race a motocross every now and then. I have a full White Bros. E-series exhaust system and have removed the snorkel from the air box. My question is will the bikes performace benefit enough for me to even mess with it. I am just trying to get some opinions from the collective.
