i wanna get a hpd primary spring to replace my stock spring and give me higher engagement. on the hpd website it says the plain spring is for atvs that want higher engagement, but whenever i read a post on here when somebody else asks everyone says the white spring. So which do i get?
p.s. my TB is all stock

 

The truth is there are many springs that will give you higher engagement. I have tried the P white spring and it does engage at a higher rpm. Not for me so I took it out.

 

The Polaris White 34/140 and the HPD Plain 32/235 almost have the same stall, the difference will be in the shiftout point. Where your machine is still stock, I would try the White. Just my .02 [img]i/expressions/face-icon-small-smile.gif[/img]
