needles
 

hi guy just wondering if im doing this JD database correct. i think i am because on the needle profile I can see the 3 tapers or just the single taper. my bike is an 04 ec300 currently running NECJ clip 1 42 pilot 175 main. i feel its too lean but the bike runs well. on reading a lot of older jetting posts it seem that the CCK is pretty good for my era bike. do i have the table correct in that the CCK is a fair bit richer than the NECJ. i dont have a CCK but have a CCK but have a DDJ so i have put that in with on clip 4 which makes it a little richer(less than 5%) pretty much everywhere so if i put a 172 main with 40 PJ its only slighty richer. my main question is am i using the excel sheet correctly with the way im punching the values in?
thx

I ran a N3EG in my old 04 300 at sea level with similar jets. The J series were very lean in mine as well.

Also a good needle an old ltr trick ddk worked great in my o2-05 250/300
