How to remove a starter motor from a Yamaha R1

Here are pictures that I took when I removed the starter from my Yamaha R1. Removing the starter wasn't so easy. Even with the service manual. You know why? Because they left out a little piece of information and I'll give it to you: how to get that damn throttle body out, to be more specific, how to get to the screws on each of the 4 throttle body rubber hose clamps that fit on the intake manifold. The manual just shows an image of removing the 4 clamps... yeah.....how? I'll show you.

Even when the throttlebody was out, it was still not THAT easy to get the starter out. Wow! How am I going to get this starter out? I'll show you. If you have the tools, you can easily do this within an hour. I took much longer since I had to figure out how to get the clamps out. Anyway, here are the pictures of removing the Yamaha R1 starter motor:
The first thing to do is to remove the seat by using a 5mm Allen Wrench

Next is removing the R1's gas tank with a 5mm Allen wrench
Continuing for the tank removal, remove the side panel of tank with a Philips screw driver on each side of the tank
Still for the tank, remove the 5mm allen bolt on each side of tank in front side.
Lastly for the tank, the 5mm allen bolt at the tanks pivoting base under the seat, for now, just make it a little loose, so you can pivot the tank up and can remove the hoses and cable easily.
Now with the tank turned up, start by removing all hoses, this pic show the underside of the tank, I already removed the high pressure fuel line. Keep removing the other fuel lines and 2 cable connectors, when done, remove that 5mm allen pivoting bolt to remove the tank and put it aside.
Next to remove is the R1's air filter housing (air filter box). There are screws all along the side, and one hidden under the rubber that my finger points at. Just pull it out with pliers. There is one screw hidden there.
Remove that connector.
Now with the cover off of the air filter, and air filter removed. Remove the  allen bolts holding the velocity stacks and remove them.
Once velocity stacks are out, you can just take out the bottom of the air filter housing. This is where the real work starts!
But before you can remove the bottom of the air filter box, there are 2 hoses attached, one in the back and one in the front.
Next, remove the 2 hoses as shown here.
Remove this connector
Next, remove the throttle cable, there are 2. Just pull it back by hand, use a thin long angled plier to remove the cable.

Okay, all done and well. How do I get the throttle body out? Here's how:  a wrench with a 12" extension with a 5mm allen key at the end, removing the side panels (not mentioned in the service manual) Okay, I didn't take picture on how to remove the side fairings, but I guess you know that, it's easy. I just remove the top screws.

At first, following the service manual, I thought, man, how can I get these clamps out with a regular allen wrench?? Answer: impossible!!!

Here is one clamp shown with the allen bolt loosened, this is the easy one, from cylinder 3. Throttles from cylinder 1,2 and 3 can be done from the left side by entering your long extended wrench from where the fairings where. The one from the cylinder 4, the clamp is pointed to the right side, so you have to enter your long wrench from the right fairing side that you removed, and fiddle it under the radiator hose.
Once all the throttle body hose clamps are removed, you can pull it off, but carefull, as shown here, there are some more hoses to remove.
When all loosened, it will look like this. I didn't remove all the hoses and cables, a bit of a pain, this being in the way, but I didn't want to dissassemble the entire bike! I'm in enough shit already! :-) Now let's get to removing the starter, shall we?
Once you remove the rubber heat shield, you can see the starter and it's two bolts to remove. Once the two bolts are out, it is tricky to get the starter out, at first you gonna curse, it's like "how did they get that starter in here?" Answer: duh, it was already mounted on the engine when they mounted the engine to the frame, duh. Okay, so how do I get the starter out? That rubber heat shield, try your best to get it out of your way to the right, and there is one to the left as well. Then, once you removed the starter cable, hold that connector with pliers and wiggle the starter back and forth so it can disengage from the transmission. Then when the starter is loose, pull it to the right side as far as you possibly can until you see the spline from the starter. i was then able to pull the spline side up and get the starter out. Same way to get the starter back in, with back first.
The 2007 starter will fit the 2004/2005/2006 Yamaha R1.

Hope you liked my procedure with pictures to remove the Yamaha R1 Starter.

The difference of an old Yamaha R1 Starter and a newer Starter

I had to remove the Yamaha R1 Starter from my bike, and when the starter was out, I compared the running of the starter motor with the newer starter I bought on Ebay for $124. this Starter came out of a 2007 Yamaha R1.
