Boyesen accelerator pump or BK/mod for my 2002 YZ 426????or bolth???

3 posts in this topic

It seems that the Boyesen accelerator pump cover would take care of the low end bog after reading up on it, but the BK/mod claims it will do the same thing just in a different way...the BK/mod would be cheaper, but I'm also now wondering if they could be used together to get even better results as opposed to an either or thing. Has anyone ever done both?? or would it be counter productive??

Not sure abouy the Boyeson pump accelerator, but have heard the best anti bog mod you can do is the J D jetting kit.

I did the b/k mod on my bike because it costs nothing but time, where as the Jd kit costs about $200 US
