Arlen Ness Air Kits

Was riding down the road yeaterday, the wife ssid did you hear something do ding, ding, ding. I said No,
She said I think something fell off yer bike, so I made a U turn and went back and laying on the side of the road was my Arlen Ness Stage II air kit. The round cover was all skint up, the filter was still there and the 3 bolts that go into the backin plate had snapped off in the backin plate.
Don't look like I will be using a Arlen Ness Air kit any more.

I had a similar problem with the cast backing plate. Where the bolts mount on the the carb, the casting material broke on two of the three bolts. Bye, bye Arlen Ness.

I have the stage one breather, and was wondering if anyone had probs with it as well?

using the SE heavy breather myself, keep thinking the leverage and vibrations might do the same but keeping my fingers crossed

Just a thought, but if bad bolts are a recurring problem then you should have addressed that issue by now.

Sorry, no sale here.

Where the threads go into the backing plate the bolt threads broke into.

This is on a Arlen Ness Big Sucker Stage II

I was very busy today and didn't have time to call them, I did email them yesterday oh.

I just contacted Mtech that replied above and will see what they come up with.
I'm supprised they didn't send me a Pm.

Contacted Arlen Ness Tech Support today, McTech said he would take care of me and my problem. So I will sit back and see what they do. McTech was plenty nice on the phone and seemed to be interested in takin care of me.
I invited him here to see what he can do to help.

I had a heck of a time with a Dremel Tool and carbided dental drill bit drillin a hole in the bolt along with a lot of drill bits, Then I was able to use a left handed drill bit to git the studs out of m throttle body.



There was exactly 1/2 " of the bolt thread down in the throttle body that I took out.
Finally got it out. It was a job oh.


Thank you McTech !

The back plate on the stage 1 kit I bought cracked around one of the 3 mount holes. I contacted Arlen Ness, and Andy May is sending me a replacement. It's nice to know that some companies still stand behind there products!!

Hey Scott,

How many miles on the scoot after you installed the stage one before you noticed this problem?

Wanna make sure I stay up on it and keep checking mine from time to time.

Got my Zippers air kit in today, also got the new Arlen Ness air kit.
Took the zippers out of the box and the backin plate would not fit on the throttle body without a gap between the backin plate and they throttle body with the gasket there. There is a HD emblem on the zippers Backn plate. Go figure
Took the A/N backin plate out, it fits perfect. Fck.
The bolts that go in threw the backin plate into the throttle body are differentlengths between zippers and A/N. The zippers Max flow is a little thicker, but the A/N is bigger around.
I notised the zippers had the right length grade 8 bolts I was lookin for that go between the button head bolts and the throttle body.. I took the studs out of the zippers bolts and put them in the A/N and put the A/N new kit back on. It fit perfect.
I notised on the new A/N kit that the button head bolts that went into the throttle body didn't have O rings like the last kit did too.

Now I'm waitin on the new A/N 8" round cover.

Yeah Dave, I had put probably put 3 or 4 K miles on the bike when I pulled the filter for cleaning, and noticed the crack in the backing plate.
Ride safe,
Scott

Just found out that if you use a SE backin plate you have to remove the brace.

I put the Arlan Ness Big sucker Satge 1 on last year and I have 11,000 miles on it with no problems. But I will be checking it before the weather clears up and I can ride again.
