Well I sealed the deal this morning and will pick up my 05 klx110 tomorrow morning (new). All of my other 4 strokes have been WAY lean from the factory. I'm assuming the klx will be no different? I'll leave the bike stock for now but would like to correct the jetting right away. What is the stock main size and what MJ would some of you guys recommend for getting better fuel flow at sea level? If the jetting is spot on from the factory, disregard, but I haven't ever found a stock 4 stroke that couldn't benefit from a bigger main jet.

if you just put a pipe on the stock jetting with stock air box will work fine. if you put a pipe and want to do a filter, buy the pps paper style filter with pre filter and an 85 main 40 pilot and adjustable needle with the clip in the middle and with a little tuning on the fuel screw it should run perfect.

turn the fuel screw all the way in and back it out about one turn. if you get the pps filter, if you get the pit boss/shitboss turn it out about 1/4 turn and turn that idle up.


thanks DAGNER, called 2HOS yesterday, what a joke, the guy that answered the phone sounded completely clueless.
