Remove faring lowers

I started by removing the right and left faring lowers

Remove Radiator

Next I removed the radiator and removed the mounting screws from the oil cooler. While it's not necessary, it will save your knuckles as well as the radiator fins.

Stock exhaust system

I then removed the stock exhaust.

Stock exhaust removed.

Here's a shot of the bike with the stock exhaust system removed. This is a good time to get in and clean up any accumulated dirt etc. You can also take a peek into the exhaust ports and make sure that the valve stems are a nice light brown color. White would mean that your bike is runnung lean and black would be rich. You'll also want to inspect the exhaust gaskets. Mine were fine so I left them in.

Install right side.

I installed the pipes in two halves, right and then left. I assemble the number 3 and 4 pipes to the 2-into1 collector and then bolted them in finger tight.

Install left side.

I repeated the procedure for the left side. Again bolting the 1 and 2 pipes in finger tight.

Install "X" collector.

Next I pushed the "X" collector into the two 2-into-1 collectors. This is where you'll have to get everything aligned and seated. I used a small soft rubber hammer to gently tap all of the joints while pushing and twisting the pipes. It's quite a bit of work, but worth the extra effort.

Break time.

At this point the down tubes, 2-ito1's and "X" collector have been installed. I've also snugged up the header bolts with an allen key. Next I removed the seat, rear tail section and rear turn signals. In addition I removed the passenger foot pegs.

Install left end can bracket.

The HMF pipe comes with some spacers and longer bolts that reaplace the stock ones. The left side of the swing arm is offset more than the right in order to provide room for the chain, sprocket and cush drive assembly. As a result, the bracket has offset as well. You acomplish this by installing the spacers next to the sub-frame, then the barcket and on top of those the passenger foot peg bracket. Use the supplied bolts and leave the assembly loose.

Left side bracket.

Here's a shot from the rear. The brackets have a slight curve bent into them along the longitudinal axis to accomodate the curvature of the can. The two holes let you mount the side of the can to the brackets.

Install the left mid-pipe

Next install the laft mid-pipe. The kit comes with four pipe clamps. I found the the best wat to orient the bottom clamp was with the threaded end on the bottom pointing towards the inside rear of the bike. This way the rear faring skirt will hide the bolt end of the clamp.

Mount left end can.

I installed the left end can by inserting it into the top of the mid-pipe and then screw the supplied mounting bolts in the can. I oriented the pipe clamp so the the threaded end was towards the inside with the theards pointing down. You'll also need to use some thread locker like Permatex or Locktite on the can mount bolts. At this point everything is loose so that you can get the mid-pipe and can properly aligned. The mid-pipe and end can have slits cut into them so that they can compress when the pipe clamps are tightened. Make sure that the claps are over the slits when you tighten them or you'll get exhaust. I was real careful with mine and it leaked anyway. So I used some Super Copper high temp. silcone gasket to seal things up. Worked like a champ!

Completed left side.

Here's a shot of the completed left side. Everything has bee sealed and the bolts and clamps snugged.

On to the right side.

The right side mounts just like the left with one exception. The end can bracket is installed in this order. The bracket goes next to the sub-frame, then the spacers and then the foot peg bracket. Since there's no offset like the left side, the mid-pipe mounts closer to the frame. Once you've got everything aligned and snugged torque down all the bolts.

Install left faring.

Before installing the farings. I cut and attached the supplied heat shield to the inside of the faring. The "HOT" spots are circlled in yellow. In addition you'll need to trim the fraing back about 1/8" on the inside of the upper left side scoop as well as the left edge of the rear skirt where it gets close to the mid-pipe.

Install right faring.

No trimming is required for the right faring. However pay special attention to the area on the bottom near small triangular hole. Don't ask me how I know.

Rear left shot.

Looking sweet!
