Hey guys. Im owning DR650SE with fcr carb and slip on muffler. I was quite happy with acceleration (still feel I have little rich/lean bog at 1/4). But recently I had chance to ride on my buddys DR with TM40 carb. It felt much different. It accelerated more...smooth. Dunno how to describe it When I twist throttle, I feel like my bike is shaking a little. More rev - more harsh it become. I started to wonder if that might be some jetting issue? I tuned it myself, he got his Mikuni tuned up. Does rich/lean might get that kind of feel? (Not suspension issue, both bikes are in good shape. We got different mufflers).
