Comparing dynojet and keihin jet sizes...

[chucked]

Is there some sort of chart that compares the sizes or something??

So if I wanted to use a 136 to a 138 size jet, I'd need to use a DJ 126 or 128?

if a 162 DJ is the same as a 180 keihin, who in the he!! would use the DJ 170 that comes in the kit. how did you find out this info? if that is correct, you are the man. i will agree with you on that. we do need to remember that the needle used can make a difference in what mainjet to use. i know the DJ needle is a bit different than the keihin needle on a 400ex anyways.

i picked up some jets today to complement the fatboy 4 i just installed... a 165 and a 167, the bag that he put them in were for a kehein 195 lol.. big boy motors there

I post this table 1 or 2 month ago with the info avaiable on the web. But I check this and my conclusion is this table suck. I build a test by myself and dynojet = keihein..... That's all..

nooooooooooooooooooooooooo.

I had a 155 dj in mine with the big gun pipe on it, I put a quiet core on it and I had to rejet to a 150 keihin, well the jet didnt fit right, but it ran good, so I tried a 150 dj, ran WAAAAY to rich. so I went down to a 142 dj (same as 150 keihin) and now it runs great!
