Hi everyone, I have a 1988 Yamaha blaster and I did a k@n air filter and vforce 4 reeds and need to re Jet my carb. I purchased multiple kits off Amazon and the thread pitch is different and won’t fit my carb.

If anyone has a link to a jetting kit that they used please send it to me.

Also does anyone know the thread pitch by chance?

And I only have the k and n air filter and vforce 4 reeds and everything else is stock. Any recommendations on what Jet size I need?

And no the Vito’s 240 jet kit doesn’t work because there jet kit comes with 300-340 jets wich are too big.

Any help is appreciated!
