[breezeblocker]

bought a new 110 jet today from honda stealership.removed old one,is slotted and round,the one i bought today is a an 8mm hexagon,about 10mm long,will this one work?it threads into the tube.thanx

[zlam27]

the old one sounds like it was a dynojet. the stock jets have hex heads. the dynojet jets are round with a slot for a flathead screwdriver.

what he said, stock are hex shaped and brass in color and dynos are round with a screwdriver slot

but by god, what are you putting a 110 jet in ??? becuase i know 300ex runs 124 stock and 400ex (coreect me if im wrong) runs 144 stock

i know many of the honda quads run with the round mainjets, not the hex. i am not sure what bike your running but i would assume it is a 250ex or recon. i know the ranchers come with the round jets, not the hex. i would take the hex back and exchange it if the bike came with a round.

oh crap, don't get a 110 if stock is 95 unless you modded it pretty heavily. if you just did the pipe/filter etc, i would go with around a 100 or so. the richer you go the less power you will have.

stock 400ex's have 148 keihin mainjets unless it had the high altitude jet put in. i believe that is a 142, but that could be wrong. you won't need that unless your stock and in really high elevation.

i am actually going to try a smaller jet that i have right now,its a 104.the idea for the 110 came from the duncan racing website.thanks,brett
