i am trying to find out if i have the right needle in the bike or not. the bike was purchased from a buddy who said he did the hrc kit to it but the bike really isn't as fast as other people are saying it should be. i.e. people lifting the wheel in first through third by just rolling on the throttle. it won't come up in any gear without a quick snap of the clutch and it has a bad stumple in the middle when i romp on it. so i tok the needle out and it reads b53e on it. is this the stock one or hop up needle. also i noticed it was at the second position from the top and i read it should be in the third. hopefully it is the right needle and just moving the clip down one will fix my problem.
