Air Intake Question

[Rick Morris]

So if this helps, I just came back from a ride of about 100 miles. I got stuck in a heavy down pour on the highway. I was waiting for some intake/ rain issues seeing that I do not have the rain covers on the K&N filters. No Issues at all. I was able to maintain about 75 mph without a hiccup.

I have run K&N stage 1 intake on my Harley for 40,000 miles through every kind of weather. So completely open behind the chrome (open back) cover. Never had any intake issues, ever. Yes, a prefilter is nice, but really not necessary especially for what K&N charges for them. The oiled filter essentially does what oil does, shed water.

Getting water in the throttle bodies has never been a care or consideration.

I ordered everything today. Should have it for a nice weekend project.

Not looking forward to removing all that duct work!

Nice it is pretty simple. the hardest part was taking the air box hose of the breather tube. A long needle nose helped that. I have also used K&N filters on just about every gas powered machine I could find them for. I did have trouble with a 72 chopped bonneville one night. It was raining like it was today and those Amal carbs sucked water right through those pod filters. It was a long ride home. I was trying to cover them with my legs and I kept getting cramps in my right leg. My buddy was on my Sportster and it never skipped a beat, he was laughing at me for about 40 miles. He sucked too.

Fully exposed I think you are probably looking for trouble without the expensive covers. but just enough coverage to keep the rain from falling directly on them is fine. I had a Thruxton that had open filters and never had a problem with them. But they were on throttle bodies and not carbs.

I wish.

I'm serious, go see Carpenter Racing.

 

[Rick Morris]

Tripps, what else did you do?

I have been in some serious down pours and monsoon rain with the Outer wears covers on both my filters and never had a problem. Even with the one that sticks out in the open a little more.

Yea, using a cover tends to work quite well. The one on my Harley is now totally exposed except for the cover and I have had no issues since I switched.

I have covers, they just aren't on. I actually just bought my second set a couple weeks ago, first set of covers wore out.

Tripps, what else did you do?

Carpenter Racing 240 hp package, imbedded in the link I posted.
