Hey guys

Quick question
My MC21 carbs came with aftermarket needles. I am wanting to return everything to stock. I have the standard needles now and I am just wanting to confirm what needle goes where.
After reading the stock carb setting page on this site do I set up as follows
Left carb (No.1) - J81E Right carb (No.2) - J3LB OR
Left carb (No.1) - 2QZ Right carb (No.2) - J3LC

Please let me know if these settings are correct and why there are what seems to be a couple of options for the MC21 carbs
Thanks Guys
Scott
