Well the Weekend was good to me! I was able to get the front end disassembled, take out the throttle bodies, and re install them. Here is Part three of the Turbo Install!

I started by taking off the Head light

Followed by the Display panel.

But I did run into an interesting problem. When I installed by tether release for my sled they installed this red light on my sled to show when the tether was attached or not.

We ended up having to cut the wire because there is no way to detach it. When we put everything back together i will end up wiring that back together.

Now it is time for the Airbox to go!

But gotta get rid of the steering column first. That was a fun time...

I thought once I undid the nut here it would just pop out, I could not have been more wrong. I had to take a metal hammer and wail on the left side of the flat plate until the screw literally was jarred out.

Then Step V

Remove the 4 M12 bolts that hold the handlebars on. Once that was done I was able to remove the steering column.

Iphone1055.jpg


Once was that, I moved onto loosening the clamps around the throttle bodies.

Where the flash hits is the nut i was working on.

Yet it did get far more difficult the further I went back.

Now with the clamps loosened, the steering column removed, and the riser column removed its time to move onto removing the airbox.

I regret to say that I am lacking pictures of the airbox removal, it was pretty straight forward. Remove all of the sensors, along with 5 bolts

In this manual it does not say to take the radiator out. But to get access to everything, it seemed alot easier so i drained it and removed the radiator for more space to work.

Iphone1062.jpg


haha by the way, this fluid comes rushing out

If you do decide to go this route, go to the right side of the sled and remove the tubing there that you see disconnected in this picture.

Iphone1063.jpg


As this is not part of the install I shall not be including a step by step process.

Now onto a detailed review of removing the throttle bodies and adding the new parts to it!

Step Y, the last step of the first set.

To begin with I had to disconnect the throttle cable. Its easiest to remove it from the handle bars.

Iphone1074.jpg


There are two screws that unscrew then it splits apart into two sections. Pull the throttle into the wide open position, then hold the cable there with a pair of pliers, release the throttle and the cable pops right out of the holding.

From there it is right onto the throttle bodies.

Start with the two coolant lines. If you removed the radiator, then disconnecting the coolant lines will only leak a little bit.

Iphone1066.jpg



Line one on right side.
Iphone1067.jpg


Removed
Iphone1068.jpg


Then the same on the left side.


From there remove the 16 pin electrical plug.

Iphone1061.jpg


haha that one took some work to find the right release on it.

Well thats really all that is to getting the throttle bodies off. Loosen the three clamps, undo the coolant lines, undo the 16 pin plug, and the fuel line.

With everything disconnected just pull forward and down on the throttle bodies.

Iphone1073.jpg


With a pull it comes right off.

Iphone1075.jpg


Now when you pull it off mind the throttle cable that is attached to it.

Throttle Body Preparation

Step 1

So now I took the Throttle Bodies over to the work bench to prepare for the load it will handle with the turbo.

Iphone1076.jpg


To begin with, take the rubber plugs off that are found above each throttle body. They are next to each gray OEM hose connectors.

Step 2-4

Find the bag with these components. These will be added to the throttle bodies.
Iphone1079.jpg


From there use zip ties to tighten down every vacuum line, along with the new ones that are installed. Make sure not to miss any!

Iphone1078.jpg


I decided to use different colors, it was a bit more fun!

Step 5-6

Next is the black IAC inlet line with the woven fabric. Remove that and replace it with the new IAC hose in the kit.

Then tighten down the ring down. After that we will be working on the fuel rail.

Step 7

Remove the 2 M5 screws holding the fuel rail to the throttle bodies

Iphone1083.jpg


One on each side

Iphone1084.jpg


Remove the spacer that is currently there, and replace it with the supplied body adapter suppliers. Then replace the M5 screw.

Iphone1089.jpg


Then remove the bolt that is not being used, youll need that to attach the adapter plate.

Step 8-10

Seat the adapter plate and use the two screws removed earlier to hold in place. Use blue loctite but do not tighten down all the way yet.

Iphone1090.jpg


Then Install the L shape brackets onto the front side of the spacer. There are two holes they fit perfectly into.

Iphone1092.jpg


Also seat these ones with blue loctite. Then tighten all four screws down.

Step 11

Remove the M8 bolt to the left of the far left cylinder, as you stand facing the front of the sled. When you remove it make sure to keep the copper washer that is behind it.

Iphone1093.jpg


Find the bag with these materials

Step 12

Take the M8 oil fitting and reinstall it with the copper washer behind it..

Step 12 continued

Take the steel braided hose from the kit and attach it to the oil fitting we just installed.

Iphone1098.jpg


I had to remove the metal clamp around the cylinder to tighten it down.

Well that's all I have done so far!

I will continue tomorrow!

Here is what she looks like so far!

Well I ran into a small problem that I mentioned earlier

We debated between replacing the wiring

We ended up just wrapping each wire then wrapping it all together

klim3003.jpg
klim3004.jpg


Then wrapped the entire thing up.

Well onto finishing the Throttle Body preparation
