1979 CB650 pilot screw o rings
« on: April 23, 2020, 04:14:30 AM »
Does anyone know the part number for these or have a source to buy them? I'm having some trouble tracking them down.

Thanks!

They only come in a complete gasket kit and there is no part number or size for them unless somebody has bought a set and measured them

I have a keyster kit with one in it, I can try to measure and you can buy them from the oring store for pennies.  Thr little wadher to go with them is another story, don't lose the ones you have.

I measured them with a caliper 5mm OD and 3mm ID for those who are looking also.

.07 ea.  Plus $7.00 shipping, so buy enough to make it worthwhile from the o-ring store.

This may not be correct. 2mm x 3mm would give an OD of 7mm.
1mm x 3mm may be better.
