PWK upgrade
« on: February 21, 2012, 06:19:11 PM »
Hi All,

New to the forum and looking for some carby information. Sorry if it's been covered before, I have a Pilot and wanting to upgrade the stock carb to a PWK, I was going to go with the 35mm (easier to fit than the 38-39mm) but can't find any info on what slide or needle to use, any info appreciated. I have dual air intake, ported, stock exhaust, PB clutch.

Also do I go with an Air striker or standard PWK in either a 35mm or 38mm.

Thanks for any help

The needle and slide in the Air Striker are a good baseline. I forget off hand what the slow jet is, maybe a 48. I remember thinking it is usable but dropping to a 45 may be better. The main jet is also in the ball park, but I would go up a couple sizes and have the one in between on hand as well as a couple sizes smaller to tune it in.

Personally, I would go with the 39 though on a ported engine.

A pipe will add more power just as it would now, but is not needed.

Your porting is pretty much useless as well with the stock pipe....You will see a major increase with a pipe and carb....I run an airstriker and love it.....

Note that the 39 is not an Air Striker. The 35 and 38 are available as an Air Striker. I run the 39 on my Pilot and Odyssey.

Porting will make an improvement in power with the stock pipe, as will the carb. The increase in power when a a pipe is added will just be that much larger with the pipe and porting already done. My own Pilot was ported before the other mods.

Thanks for the replies, Hoodlum any idea what needle you are running? What mods does your engine have?
