All,

I need some help. I am having some work done and am not sure what to do, so I am going to throw rocks at the hornets nest. I need to know what kind of air cleaner to run. Here is the work being done. 1976 kZ900 LTD, back cut transmission, welded crank, 1075 kit @ 10.5:1 compression, .400 lift cams with short duration, Intake boot port, exhaust ports opened up a bit as well, Vance & Hines sidewinder pipe. I have a set of 29MM SB’s that I am going to run. I have a stock airbox, with K&N air filter. I also have a modified airbox that the hole on the intake side of the air cleaner has been made bigger to flow more air that the K&N will fit into. My question is should I run one of my air boxes, or should I get K&N pods. Please let me know your thoughts. Want to try and figure out which way to go as if I am going to run pods, want to get them now. And if you guys vote pods, should I get the K&N, or is there another cheaper option that work as well? Lemme know guys. Thanks!!!!!

You may as well go for the pods. I'm not a fan of pods generally speaking, but with a modded bike such as yours pods seem like a natural.

APE pods are reputed to be nice and they are quite a bit cheaper than K&N's. I'd stay clear of Emgo's and the like.

I had pods on 29 s with a very similar engine package. I cant remember jetting as it has been many years , but I sorted it out and the bike ran great idle to full WOT and at mid range while cruising.

Dump the stock air box for sure!!!!

Thank you....any ideas on the jetting??

i run 20 pilots and 120 mains. You might start off higher on the mains, say 130 then work your way down if needed.

If you do remove the airbox - DON'T HURT IT and don't lose any of the related parts. They sell for quite a price on eBay. Ed

If you think you'll be riding in the rain ....then I suggest using the modified air box with the K&N filter.
You won't be able to tell the Power difference ...
