Never thought id say this but the IRS was good to me this year... Anyways I have a HMF slip on and a skid plate along with a WHT bros bumper, AC swing arm guard and a EHS Racing lid on the way to me. The question i have is about jetting??? I live in Las Vegas for the exhaust and K&N air filter with the EHS Racing lid what jetting would you recommend? Any help would be greatly appreciated.

IRS on a Z? Is this a kit?

I would start with a 155 or a 160. You'll have to play with your airscrew. Probably out a half turn or so over stock. Maybe smart to get the Alba needle kit. It comes with an adjustable needle and a few jets. Look on their site. I don't think you would need to bump the pilot yet. depends on how far you take the airscrew.
