I am from South Africa so importing the o-ring can be quiet expensive. Can you please help with the o-ring sizes as I am trying to source them locally to save cost.

From Tony sleep website I got this list, please advise if correct

ID Cross section OD Hardness Quantity
Main jet 6.07mm 1.78mm 9.63mm 75°Shore'A' 4
Float perch 7.65mm 1.78mm 11.21mm 75°Shore'A' 4
Slide holder 10mm 1mm 12mm 75°Shore'A' 4
Idle screw 2.5mm 1mm 4.5mm 75°Shore'A' 4

Are there any additional seals/o-rings I should get?

Many thanks

One of your GSXR brothers will be along shortly.... he sells the kits at a superb price..so might be worth your while getting them from him.
