Looking for a street legal SM for playing on the street, not racing. How much money will I have to put in to a DRZ400SM to make it run decent? I had a 400s a couple of years ago and sold it after 3 weeks. It was a SLUG! So, I'm thinking full exhaust, 436 big bore, maybe FCR carb? With these mods, is it anywhere near the performance of say, a KTM 640? I'm open to any and all suggestions. Oh, and don't say "just get a 625SMC" because they are pretty much impossible to find around here and even IF I could find a 06', I'm not paying 9 grand for a SM!
