    Hello xj peeps!

    I may need some help on putting the carbs back on my xj650 maxim
    K so under the diaphragm there is a half circle metal plate and under there are two jets which look to be the same size from the head but the jets are different size. My questions is does the big jet or little jet go on top ???

    The other question does any one have a photo of how the float bowl covers go from left to right ? I mixed the bowls up :(


    Thank you

    copied from chacal's post here http://www.xjbikes.com/Forums/viewtopic ... r+jet.html

    The main AIR jet goes directly above the main FUEL jet, and likewise for the pilot AIR jet.........it is located directly "above" the pilot fuel jet.

    The main AIR jet is fitted to the "center" hole in the area under the vac piston diaphram and is the SMALLER of the two air jets. The pilot AIR jet is fitted in the forward-most hole and is the LARGER of the two air jets.

    The above info only applies to Hitachi carbs

    For the float bowls, hold them in your hand as if they were on the bike. The left two should have the drain screws point left the right two to the right.

    you should have a big and little jet on both the top and the bottom.

    The jets in the float bowls are your FUEL jets.

    Those under the diaphrams in the hats are AIR jets which is what I posted about.
