Boyesen Accelerator Pump Cover ??

Anybody tried one of these yet, they say it will smooth out the hit a little and create a smoother transition of fuel. Or will it be just another $80. :)

Let us know when you try it!


I instaled one on my '02 YZ426F and I have no complaints. Works as advertised.


I thought the "Yamabog" could be solved with a different accelerator pump ("leak") jet for less than $10. :)

This is the exact same item as the P-38 Lightning, but more expensive.

I was wondering how long it was going to take before someone started producing knock off's of this successful item.

Bonzai :)

isn't it a whole different animal on the 03's and up?
