raptor jet kit on 400ex

[400exfan19]

would a 660 raptor jet kit fit on a 400ex? wats the difference?

Dont get a jet kit for just a pipe and a filter. Go with a main and a pilot for about 4$. Its better than paying 25$ and if you do get a jet kit buy one meant for a 400ex. I wouldn't even run it until you get one.

i already have the jet kit, im just wonderin if i can use it with the ex. really, wats the difference?

[blasterandy]

Needle i wouldn't use cause i don't know the sizes. The difference is probably the jet sizes if it has main jet sizes from 148-168 those would be ok to use. And a good pilot jet size is 40-42 i use a 42 it makes it much easer to start. I use to go thorough about a spark plug each month now i have to change it every 2-3.

i have it aftermarket jetting alread but im puttin new parts on it and have to change the jetting so im just making sure that i can put the 660 jets in and theyll work

[underpowered]

no they wont. a raptor has mikuni carbs and a 400ex has a keihin carb. they use different jets. the raptor jets will not fit in the 400ex.
