Jack Shaft kit

[Berty]

I'm sure it's been asked before but does anyone run a Jack shaft kit on their bike? I was thinking about adding it to my 212 predator engine but I wasn't sure if it would be worth the $$

They are for riding up hills and Adults but loose top end

If you like your top end leave it alone

I like them personally. Just means you need to turn the engine to a higher RPM to get the same speed. I have a PMR jack shaft on a yard kart that I'll turn to 9000, has a hell of a bottom end and will still do 50.
