Howdy All,

Will be installing my Kuryakyn hypercharger and Infinity streamliner on my 07 Fatboy this weekend. Have never done it before so any advice on any problems I might encounter would be greatly appreciated... especially from the perspective of a novice such as myself.

Having said that we managed quite nicely with the Big Radius exhaust and PCIII a couple of weeks back... so I am hoping this is just as easy.

I am assuming the tank needs to come off for this? Any help with tank removal instructions would also be greatly appreciated.

Regards,

The tank removal is the worst part of the job. I would recommend siphoning the tank as much as possible first before draining and removing. To remove you have to cut one of the factory fuel line clamps (one time use clamps) that connects the crossover line from each side of the tank...it runs through the frame so it has to be removed from one end. You can replace this clamp later with a regular worm drive type hose clamp. The tricky part is not getting fuel all over you since there will be two sources of fuel wanting to flow when you disconnect the crossover line (one from the nipple at the bottom of the tank and one from the crossover line). I used a needle nosed vice-grip to gently pinch the line close to the clamp I was NOT removing. Then, I had a 2' piece of fuel line running into a gas can. As a pulled off the crossover line, I let the little bit of fuel in the line spill onto a rag wile I quickly connected the 2' fuel line onto the nipple at the bottom of the gas tank.

As for the bracket that holds the throttle and idle cables to the manifold, just simply loosen the adjuster up on the hadlebars to give you room to play...you don't have to remove the cables from the barrel on the manifold.
I hope you have a service manual...It comes in handy since the pics kuryakyn provide aren't great. There are other wires and the main fuel supply line you need to contend with also but should be easy enough if you have a service manual. The one simple thing I over looked was during reassembly of the fuel supply line connection. It's a quick connect type where you lift up on the sleeve while pulling down to remove...Well, when I reinstalled the line I pushed it up until it clicked and thought it was good. However, after not being able to start my bike afterwards, and realizing it wasn't getting any fuel I checked this connection again pushing up and getting a satisfying second click that did the trick. Good Luck!

 

I might suggest that you go down to your dealer and get the braided crossover line since you taking the tank off. It's a bit pricey but it does look nice and it screws on vs. using clamps.

 

Why does the tank have to come off? Never had to do that with mine.

I did have to lift the rear of the tank while installing the Mikuni carb.

Be careful with the tank removal have see a few break stuff if not following the directions in the manual. Removal of intake manifold is ment for someone with hands of a child, there is not much room but if you buy the right tool it is a snap, I ended up using a 1/4" cut hex key and small wrench. Taping for the vacum line is smooth since the metal is soft just ensure to get the correct size drill bit & tap.
Have fun that is what its all about.

 

Well it seems you have a 1990 carb model, and he has a '07 fuel injected model. You have to remove the tank to get to the manifold. Once there you have to remove the MAP sensor and place an adapter between it and the manifold to use the vacuum pressure to operate the butterflies of the hypercharger.

 

Interesting. Was this for an '07? I didn't have to drill my manifold. The adapter was designed to be held in place by the throttle bracket. Once it was tightened back down it held in the MAP sensor and adapter firmly.

 

Ahh, didn't know the fuel injected bikes doesn't have a vacuum port available like the carb bikes with VOES.

I have recently installed one on my Road King. I can tell you that the tank DOESNOT have to come off to install a hypercharger on an EFI bike. The hardest part is getting the throttle body off - you have to remove the horn and with a LONG torx key take out the stock Throttle Body to Inlet Manifold screws from the HORN side of the bike. You then fit and a vacuum takeoff adaptor between the Inlet Manifold and the Throttle Body and using the longer supplied screws tighten it all up. The vacuum adaptoris supplied in the kit with all the required gaskets and is needed to allow a vacuum take off to operate the Butterflys on the Hypercharger.

The next stage involves taking off the Head Breather bolts from each Cylinder Head and then fitting the support plate to hold the Hypercharger to the Cyl Heads.

It's pretty easy to do - so don't be put off. Once you get the throtle body torx screws out its pretty much plain sailing.

 

actually the throtle body on the 07's is not seperatefrom the manifold, thats why you have to take the tank off to install an adapter between the "map"? sensor and the throtlebody. Its either that or drill a hole into the manifold and install a bung.....over the winter
