BS38 Needle jet/ main nozzle O-ring

[snoosky]

I'm trying to find a replacement o-ring to my needle jet. Apparently due to the pandemic or who knows why, Partzillla and Bike bandit are both on back order. Wondering if anyone has tried a regular hardware store o-ring? These things are super tiny and I'm not even sure what size would be correct even if I found some. I've got all my other parts and now this is hanging up my riding!!

I am reasonably sure it is 1mm x 4mm and available from these guys, among others.

I sure hope someone else can verify.

Yes, that size works. But, Suzuki used very similar BS carbs on many of their bikes and you can get that o-ring from them, cheaper than Yamaha too. They even list the actual size, and it's pretty oddball. That's why we use the more commonly available 1mm x 4mm .....
