Jet ID

[HooliganCycles]

I was going thru my carbs today, i have a 77 with what i believe are stock bs38s, 25 pilots 122.5 mains which i also believe is stock jetting, when i pulled my pilots i noticed there are no holes on the sides of them, isnt there supposed to be? Or is this how they are suppossed to be? I was looking at the tech section and the pictures i saw show holes.

Yamaha used "no hole" pilots in some of these bikes, not sure why, so I would say what you found is normal. The more common ones with holes will work as well. The '76-'77 and '78-'79 carb sets seem to be the ones that came with the "no hole" pilots.
