Busy day today

[WindyOne]

After waiting forever for good weather I was able to get out in the shed to work on the FW.
I put new mirrors on.
I put on the cable for heated gear.
Installed the rider backrest.
Installed an external breather system. This took me the most time. I wanted to keep the stock air cleaner housing. I had to make clearance in the partition between the lower and upper cleaner screen on the housing for the hose. I drilled a 1/2" hole in the center bottom of the housing for the hose to exit.
For the life of me I don't know why HD put a security allen head screw to hold the cleaner screen to the backplate? I can tell you it did not get put back in. I don't know what the size of the bolt is,but I found it's replacement in a bag labelled exhaust cap screw.

This leads me to ask about a 2021 stock replacement air cleaner. The OEM one has a hole in the back that HD uses for their version on the breather system.
Can you buy one that doesn't have that hole in it? I don't know how much air can find its' way into that hole but I would rather have a filter without that hole.

My FW only has 24 miles on it and I found a coating of oil in the throttle body. Hopefully I won't see that again with this new breather system.

Just put some masking tape over the hole. This is what most do.

I thought about putting some Gorilla tape over the hole. But the nagging fear of it somehow getting sucked into the throttle body held me back.
In my travel for errands today I am going to see if I can find a plastic plug that might work.

Yep. Or like you said, an automotive plastic body plug. Most Body Shops keep a tray with a selection of them or try an Automotive paint supply store. Make sure and put the lip on the outside with either one so there is no way it will get sucked in to the motor. I would not use any kind of tape. Depending on the size of the hole, you could also use a short bolt with a fancy head on it. Make sure to use a nylon locking nut or locktite though. If it’s a bigger hole, add a fender washer to either side of it. I always use stainless for something like this.

Sorry, I keep editing my post above. Have you got a Menards near by? Get on their website and search for “hole plug”. They have a BIG selection to choose from and even small little ones. Chrome, plastic, sheet metal plugs, etc. They are in the big sliding cabinets above the bolt section.

BTW, you said you were venting it. Curious how you are doing yours.

I’m getting ready to do mine and have the Fuelmoto AC/DC air cleaner with the adapter to put the stock Harley cover back on.

I was planning on putting the stock breather bolts back in and have some 1/4” vacuum line and a plastic Y. Will run the vent hose back to where the fuel vent hose is at and if it drips, it drips.

I used the existing Harley breather bolts on the stock air cleaner housing with black fuel line running down each side of the filter to a "T" fitting. I drilled a 1/2" hole in the bottom of the stock housing and ran that line forward zip tying it to the frame holding the brake line. I connected a reducing connector to the 5/16" hosedown below the brake pedal. I bought a https://www.amazon.com/dp/B09CY4FDBB?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
I drilled a few small diameter holes not fussy where I put them and connected it to the line.
All the parts were about 20-25 dollars.

No Menards close to me unfortunately.

That is exactly what I used. Gorillas tape on the outside of the hole. Been fine for four years. I see no reason to change. Besides the vacuum on that small hole compared to the large air filter is insignificant. You to really don't have to go extremes. If it makes you feel better the choice up to you.

I’ll add 4: eBay- never sold anything on there but always ordering some esoteric part that I can’t find anywhere else!

It is nice having a NAPA store right around the corner from your house. One of the .benefits of living in a small town.

I agree, NAPA stores have a lot of specialty parts that you won't find at the other big chain auto parts stores. They are more geared to the local repair shops, farmers, etc, and may why they target more rural communities, but they are also common in most bigger cities as well.

We have a Do it right hardware store in town that sells just about everything and anything odd. I go there a lot. They usually have it. You know that widget.

For anyone that needs to plug the hole in the back of the stock air filter. The hole diameter is 1/4" and the 7.14MM or 7/25" plug is the one that works.
