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

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
