First of all, thanks to CerealKiller for the great thread he made, without that, i wouldnt get this idea of making one myself. The only reason why i tried this is because the glue keeps on coming off and i was frustrated as hell.

I found another way to do this easier, well if you have patience then yes, it should be easy, these are the materials you need.

1 Mending Brace 3 in. x 5/8 in. - available at ACE Hardware, it comes in 4 but all you need is one, cost is $1.85
JB Weld or Super Glue
Grinder or a Demel Tool with Grinding Bit.
Drill
Size 8 Wrench
And your STOCK SERVO MOTOR PULLEY - The stock pulley has a lock underneath for the shaft.

First, drill the Mending Brace in the middle with a bit that will fit the stock bolt through it. You'll see it below.

Second, place the brace on top of the pulley and mark it with a marker on the part where it should sit in. Start grinding until the brace would sit flat on the pulley, make sure that it has an exact fitment, you dont want to have slack on the brace while it is turning, you'll see what i mean below on the video.

Now, make sure that the notch on the servo is 12 o'clock like what CerealKiller mentioned. you can see below the 9 o'clock and 3 o'clock i wrote.

Now install the pulley with the brace on the box but make sure the brace sits flat on the pulley and put glue or jb weld under to make it super strong kinda thing. When tightening the bolt, make sure you hold the brace and pulley good or else you will damage to motor.

Thats it, turn on the ignition and check if the FI light is still on, Here is the video on how it should look when turning. Make sure the Brace is hitting the box to make it go back and forth.


Patience is the key. Good luck. Im a little sleepy right now coz its 1 am in the morning here so if you dont understand some of what i am saying, dont hesitate to ask me lol.

Oh, you threw your stock pulley into the mix. Clever...

The only downfall that I can possibly see, is that you would no longer be able to use it, if you wanted to reinstall the stock exhaust...

Still, if you know that you're not gonna do that, then this is a good idea.
Yes you can still use the pulley, look again :D

clever but way to involved LOL my fix was a 1/8 inch thick aluminium 3x1 in I believe a hole drilled in the middle install LOL no glueing just a quick snip and drill. The hard part is making the position perfect so the fi light goes off which if not done perfect on ur setup could pose a problem since it isn't adjustable but still very clever

thank you for posting this up it does act like its working like in your video but my fi light is still on but i think it may be because of my secondary throttle motor is fucked up.
other wise a good fix, thank you.

an update from me guys...
the servo-motor keeps going back and forth ...like forever.....hahaha
seriously I don't think it stops doing the thing(back and forth in the left) like the video in the first 6-7 seconds!!!When I first installed it and tested it took a little longer but eventually stopped!!
Can this do any damage to my bike??

yeah my bike starts kind high when cold, then settles down after a little bit. Has always done that. Your car does the same thing when you start it, revs up to get going then settles down.

I know this is an old post, but still very useful.
Mine had a broken tooth where someone was messing with it before. had to take it apart and spin 1 of the gears until I found the sweet spot where that 1 tooth wasn't an issue. Then I couldn't remember which way the notch went until I found this post.
Awesome!
