After reading all the jetting posts I'm a little confused on which yz carb needle to try on my wr400f..I want to go with something that will give me a little more mid to upper power,and see that the EKN needle is recommened alot,JD and Taffy seem to be the experts on this subject,so any advice from you other experts would be greatly appreciated..My carb setup as follows:
stock DRS needle #4 pos
Bike runs good overall except for the fact that my pilot screw has to be at 3-1/2
turns out to run smooth from idle to 1/4 throttle..Everything on this bike is stock wr timed factory pipe,air box lid has been removed,grey and blue wire has been disconnected...
I know jetting can be trial and error but I need a good starting point,live in Georgia,900 ft above sea level,it's always humid here,summer temps avg 85 to 95 and winter temps average 35 to 55 f
Thanks guys for any suggestions you can give me :thumbsup:
