Cold air and pod filters.

Does extremely cool or cold air mess up an engine equipped with pod filters? Say, if you're heading out in low 40s or high 30s? My '77 KZ650 has pods on it and I'm wondering if riding when it's that cold might have some kind of bad effect on my engine/jetting... just curious.

I don't think temperature is a problem, but rain and crosswinds are the main headaches you'll see running pods, and the weight of the carbs on the intake manifold rubber takes its toll. Find a way to support the carbs in the rear.

Can't think of any harm to the engine done by air in that temperature range, in fact mine seems to like the cooler air. But then, high 30s low 40s is too cold for the pilot!:pinch: Be interesting to hear from some cold climate members and some of these guys that ride in the snow. The main thing I'd be concerned about is condensation.

I've made some simple support straps for the carbs so they aren't just hanging on the manifold boots. I'd recommend this as it helps for smoother running, too.

Why would crosswinds mess up a set of pods? I could see how a soaking rain might (ha ha, WOULD) be an issue but wind?

No problem at all. Cold air is denser/heavier so the bike seems to run better. I have pods.
No problems with condensation and as for snow - that's what snowmobiles are for ....wish I had one.

Wind just messes up the flow of air into the pods for lack of a better way to put it. (Or lack of knowing the exact answer).

blows the air away from the pods making a temporary rich condition

It is my opinion that given a certain amount of cross flow of air at some velocity at right angles to the pod would result in a somewhat low pressure area thereby causing some reduction in and reversal of the vacumn needed to pull air into the carburater intake.

yeah like harry said!

My bike would bog down for a moment at times with strong cross winds, when I had pods.

Rode yesterday...it rained a bit,off and on...pretty windy at times,and I noticed a difference in how the bike ran.More popping than usual,and some hesitation at times.
(I'm running pods,btw.)
