Ap Mod On A Yamaha?

Has any one succesfuly done the Ap mod to a yz450f that red beard came up with for his crf450?

Yes I did.

What does this do for the accelerator pump and does it work with the Boyesen quick shot, or does it not matter with it?

If you are refering to wiring the AP, then yes I did it on my 06.

I want to know if you notice a huge difference in throttle responce like I do on the crf450? I stoped with the shorter diagphram, O ring, Quickshot and did not go for the #80 or 90 leak jet because I did not want to tarnish the rideability. Its enough like this on the 06 crf450. Is it the same for the yzfers?

The "bearded one" tried it and it did nothing for his yz450.

I bought one and installed it after the AP pump mod and the bike did not run well, I removed it and took it back.
