This mod isn't for everyone,i mainly wanted to retain stock look as much as possible including hoses etc.
So...here we go drilling into brand new 28mm pwk's.
Start with a 3mm drill bit & drill through this spigot/nipple to the intake tube.
Then take a 4mm x .7 plug tap & tap this hole approx 5mm in,drilling through for the vacuum cross drills into this circuit. Its not used as it is an optional bowl vent. There are 2 vent holes & the other side is used so all good.
Then take your 4mm grub screw that has a slight coating of fuel proof thread lock & tighten into place.
Ultrasonic clean carb & blow it out to clear any chips etc from drilling & tapping & you're done. Make sure your thread locker is fuel proof.
Oh,then ride & enjoy.
