Needle and needle jet are as I recieved bike back in January...likely original...but odo shows 8300 miles and that seems a legitimate mileage for the overall bike condition. I have not tweaked any carb screws since getting it back from shop last week. They spent quite a bit of time tweaking it and I didn't want to stray from those settings after spending $300 for their "pro" efforts. Prior to shop work, I had the pilot screw at recommended 1 1/2 turn out.. and fiddled it in/out upto 3/4 turns to try to settle idle. Never got it nice and low like the shop did, but note it had a stumble even then, before shop touched it.
