Hi @ all,

i have a Predator 500 with the Subaru Engine.

I bought the 558 Wiseco BigBoreKit with a sleeved Cylinder.

Do i have to change the valves and valve springs or can i just Plug and Play with the OEM one´s ?!?

Greetings

You will be ok with the stock stuff unless you go to a different cam. Then you need to worry about the valve train.

Air filter w/outterwere right on the carb
Remove the air box

Hi,

I have the Leovince X3.

Did you leave the rest original?

Only change Cylinder and Sleeve?

Yes I only did the stock carb mod filter on carb (no air box)
And the 574cc big bore at the time
The jetting should be good between 160-185

Nicholas cycle did the work

hes right on im guessing right around a 165 with 2.5 turns out on your a/f thats what most hpd kits are running on @ polarisproriders.com

 

[LogDoc]

What does a/f means?
