Default Big Sucker Installed

I installed the AN Big Sucker on my 2012 FLHTK last night. Definately made a difference in the way the bike runs. It was the last link in my stage 1 setup and surely one that was needed. It really woke the bike up and it's running really nice now. The AT should be here tomorrow and then that will go on to finish up everything for now. Then the decision as to whether or not to change out the cams. Does it ever stop????

Never ends! I put cams in last year to gain some low end torque and wake the exhaust up. The cam is mild and I said that is all I need. Now, I am planning this Winter to go with a big bore kit and new pistons. Just ordered a set the other day. After thinking harder, I am still hungry for more so I plan on porting the heads for a better flow. Why can't I just be happy with what I have

Glad the AN worked on your bike.

I installed one on my 2012 and found the fit less the adequate (purchased new directly from AN). Had to smooth out the surfaces to get a better fit.

Then I found the AN seemed to suck a lot of oil out of the breathers causing a mess so you might want to check that often.

I also did some tuning/data runs and found almost no difference in the VE's between the stock and AN systems. In short, I went back to the stock system with much better results.

Personally, I would not recommend the AN to anyone.

Can you share your data.?--- I wonder if you exhaust tract was still stock/restrictive or if there was a performance high flow exhaust system...both flow bottlenecks ( intake/exhaust) need to be removed to get increased flow through the motor ( generally a gain of 7 to 10 horsepower will result from the removal of these restrictions- depending on which components are chosen)


I recall testing some years ago which has numbers like


stock 134 CFM

Ness 260 CFM

S/E 270 CFM

The latter both exceed the theoretical limits of the motor.

( other numbers:

no air cleaner 110 CFM

cupped hand 150 CFM

Zippers 280 )



After running S/E for years on evos- and installing many on other bikes- i find that the Ness Big Sucker is a better value in terms of appearance ( chrome backing plate) ease of install and filter media ( washable oiled)--- and cost. about $120.

- and with either system, no undue oil condensing from the breather mist- the heads vent a mist of oil and air which has to be directed properly to the intake.

Recently completed Stg1 with AN bigg sucker, V&H power duels and SE tuner (have it dyno'd after all is installed. Made all the difference). Running OE cams (103 Ultra Limited), thinking maybe new cams next yr. Want to ride this setup awhile and do some research on what I want power wise. There are so many options with cams (low end torque or high end hp).

Very happy with the Ness Big Sucker. The install was simple, the chrome looks great, and it seems to work real well, no oil drips at all. I'm curious about the numbers as well.

Sorry for your bad experience. Mine has been just the opposite. I will keep an eye on the oil situation, thanks for the heads up. Install and fit were flawless. Based on sound of the intake, the response and seat of the pants feel, it is no where near the same as stock. My stage 1 modifications consist of V&H Monster Rounds, de-catted stock headers, AN Big Sucker, PCV (with AT by this weekend). The bike is running cooler, quieter and easier than before with much more get up and go. It is completely different today than it was the day I rode away from the dealership. I am extremely satisfied thus far.

I installed a PCV with Jackpots and unrestricted header using stock air box with a KN filter. The last step was Stealth breather and felt no real diff (seat of pants). In fact the map Jamie sent me def shows added fuel to many areas so I know it wasnt still running lean anymore but to say I felt an incredible diff would be disingenuous. But to go with the OP theme the intake was less than impressive. I think its as good as its going to run without a dyno. Im guessing it already had all the air it needed and the open breather wasnt necessary.

Aren't we glad that they are not all the same? I'm extremely pleased with the changes in mine.
