Can someone please help me with increasing the horsepower and torque of my 07 Rubi. I was thinking of a jet kit, after market slip on exhaust, air filter, etc.
What type is the best ?

 

my advice would be what you said and maybe also a header like a powerbomb or any 4stroke header by fmf or pro circuit. i think a cam could help build up some speed

 

How about a blower at about 10 pounds?

 

cam is about your best bet is the cam opition, because after 05 they put different cam in the ruby's. Hot Cam makes one and also Web Cam which is the one that I put in mine. Get a good after market air filter I chose Twin Air. I alos have a pro circut pip on mine. Check with your local DNR first on db levels, and you want one with a spark arrestor. If your running bigger than 26" tires a EPI clutch kit would be a good investment. All these parts would be around 650 to 700 plus labor to install them.

 

My brother just put all that stuff on his Ruby, didn't gain much if any. We still run side by side........But his is noisier and uses more fuel.

 

I also did the carb spring mod. And when I rebuilt my motor I polished the head
