2008 YZ 250 JD Jetting? and Boyesen Rad Valve?
Posted August 12, 2009 - 01:24 PM
The bike I bought came w/ the Boyesen Rad Valve and I am wonderng if any of you have any experience w/ JD Jetting? Do any of you have any experience w/ the Boyesen Rad valve? I dont.
What about JD jetting and the Rad valve together?
Broad question I know but the rad valve instructions say to use 1 size leaner main and possibly pilot. I know JD's kits have a tapered needle and are set up leaner than stock already.
Any input would be great. I will post some pics when I get her finished and once I have a chance to ride her this Sunday
