Guys I urgently need to order a set of main jets for my 2000 Yamaha r1 but the website from where I usually order gives a range of sizes for the main jet ranging between 0.78mm to 1.9mm

Can anyone tell me what the original/normal size is for a main jet?!! I've got everything stock...just a Harris exhaust and I just replaced all pilot jets (standard).

Your feedback would help!!!
