got my bike from my mechanic yesterday 07 dr 650. the carb was cleaned tuned with stock jetting. also the needle was shimmed. here's my concern is the idle circuit was drilled. the bike seemed to run great on the 1-2 mile test ride at the shop. lots more bottom end power, the rear tire felt like it wanted tear out from under the bike. could there be any issues with this mod? the bikes got a k&n filter,snorkel still on,super trapp with 6 plates.
