Stock sm model? The carbs are a big hold back on the street models. I had an e model converted which was higher compression, flat slide Carb, full exhaust and modded air box. Stock bikes make 31-33hp. My dyno'd 41 several times over the years. Granted it still sloe compared to superbikes but huge difference compared to a stock drz. Anyway Ryan I'm gonna need a 21x3 Enduro tire real soon.
