Primary Spring difference??

[YamahaFreak]

Can anyone tell me if the stock Primary spring from the Nytro and a stock primary spring from a 2014 SR Viper are the same? Rebuilding my clutch on my nytro and my dad has stock spring from viper and was thinking about putting that on my nytro for a better stronger/newer spring.

What color is the spring from the viper?

Blue Silver Blue

Stock nitro is yellow silver yellow. That tires spring will cause a higher engagement and most likely lower top r's

 

[radianguy]

Blue Silver Blue

Is it viper xtx? That is the spring from nytro xtx too.
