[ricks450]

does keihin make a adjustable needle for the 05 and newer 400ex's? that you can get or will the 04 and older needle work in the newer carbs? thanks guys.

Yes, the 99-04 needle will work.

Best wat to get one is on E-bay serch for a carb rebuild kit and you will get the needle and a pilot screw that is not D shaped for 19.99 plus shipping or you can but just the needle for 22 from honda

do you guys think that the keihin adjustable needles are better then the dynojet ajustable needle? are the tapers differant? thanks guys. :)

The tapers are different. Dynojet says that there taper produces a flatter A/F ratio. I dont think it is worth the difference in price I mean I payed 23 with shipping Dynojet wants 49 - 59 plus shipping plus the K jets are easier to get and use

i got the dyno jet kit and i cannot get this bike right with this kit. the needle has got to be the wrong needle or it is not what i need. when i get this bike running right on the bottom and responding good it runs to lean on the top side. i got the biggest jet in it (that comes in this dyno jet kit 170) which is egaul to a 190 keihin. i think. i put a 165 in it and it was to lean it turned the plug white with a blue tint. way to lean so i went back up to the 170. i still would like it to run a little richer up top. i can richin the top buy pulling the needle back up (not as much as i would like) but it runs way to rich on bottom to mid. no matter what i do with the air/fuel screw. so i was thinking i would try the keihin needle. i can get the bike to respond good and give a good reading on plug on first clip and 3 1/4 out, but way to lean on top side. the needle is not coming out far enough. this on 170 main. so i put the needle on third clip and it riches the top side a little , but it makes it run way to rich on bottom no matter what i do with fuel screw. it dont make any sense. this not the first time i have done this. so im not new to this. i just do understand what is going on with this kit. i know i need to go up on the main to get the high end where i wont it but thats not going to fix the low end. thanks guys for all the info. :cool:
