There is a pic in his garage.I understand now.So all I have to do is wrap wire where you have it in the pic?Like I dont have to do anything else?Does it matter how tight the wire is?

yeah make it super tight, if it falls off it could get stuck somewhere and something bad could happen, like the throttle sticking.
I am always really careful when I do wire pumps, I put the wire on and pinch it down with needle nose pliers to ensure a good fit.

It forces the fuel in instead of relying on a spring to push the fuel in.Do you know by chance what guage wire you used to tie the pump with?I figure since its a big pain to get to the carbs on my new 250f and 450f I use at least have all the stuff to do it right with.

I have a picture in my garage of the mod.

Is it the same for a 426? Is this the BK mod everyone talks about?

kizzle- no the BK mod is different, but is also supposed to improve throttle response. A search may bring up the post about the mod, if not PM me and I'll try and fill you in.

I did this mod this past weekend and noticed no more low end bog and dare say ( it didnt want to hot stall )

Real quick mod i think any gauge saftey wire will work.. I kinda bent the wire in a U shape and took the ends and kinda curled them up wards like > C <
to loop it around the AP and throttle thingy.. :thumbsup:

Hey Guys, the fellas from our forums linked this, I just wanted you guys to know that in conjunction with RedBeard450, I made a 25 Page How-To Manual for this. It will be avail in the CRF450R forum, under the Rediculous Throttle Response Thread, We finalized it this morning, and I am awaiting my Webmaster to Reset my FTP Login so I can get this Article out. This will work with any Carb that has an AP.

I wish someone had a picture of how this supposed to look after its done. I have an idea after reading, but still not sure how the finished product should look.........

Anyone??

Also, someone please answer my question where I was asking:

If I have a Boyesen Quickshot, is it still beneficial to do the AP mod or does this mod do the work of the quickshot thus not needing the quickshot?????

I have a '03 YZ450F Thanks!

Chills has a QS on his bike and his bike responded very well to the mod. Check out the thread in the CRF450R forum and you will find all sorts of pictures, but I suggest waiting on doing the mod until Chills gets the link to the article he wrote up.
Here's the link. http://www.thumperta...7&page=54&pp=10
