Ok guys, I did a search and found some info but I'm just not getting the answers I think I need. My original plan was to buy a DRZ400S at the end of the month, but I was just offered a DRZ400E that has all the necessary mods to be street legal. Here's a couple of questions, first and foremost I know the E model has a higher compression, what Octane fuel should I be running, I know that 91 is acceptable according to Suzuki but is it really?? One of the reasons I was getting this bike is to cut down on fuel costs from driving my truck at 14MPG Also, I'm just looking for a basic pros and cons list of why I should get the E model. Any disadvantages? I liked the idea of the way cool LCD panel on the S, but it's not really important to me. Anyway, let me know what you all think.
