7000 does, can't confirm Viper

I believe Yamaha uses borg warner chain. Borg warner is also the company that developed the hy-vo chain. I'm not sure if they still own the exclusive patent rights to hy-vo or if other manufactures are copying it. I'm thinking they make a drive chain with a 15P that would fit your sprocket pitch.

The gears from Yamaha viper are also supposed to be billet steel instead of powder metal but I don,t know if the Yammy parts will fit the cat
