I need to get some jets for my 440 kit, but the Honda dealer I called can only find part numbers for the standard size 400EX jets. I need 160, 165, and 170 main jets and 42 and 45 idle jets. Does anyone have the correct part numbers I need? or do you now who I can call to get them? I have some jets that I used with my 250R, but they do not look the same, so I am afraid to try to use them even though they do have the same thread pattern. Any help would be appreciated.

the part # is 99113-GHB-xxx0

xxx refers to the size of the mainjet your looking for. for example, if you want a keihin 160 the part # is 99113-GHB-1600.


for pilot jets:

the part # is 99103-420-0xx0

 

Thanks, got them ordered.

45 or 48pj, and a 172mj should set you up with an open K&N filter.
