OMG!!
you guys have your own racetrack ,
thats an awesome private sm playground
@doordie ,
your bike is geared the same as my sumo(see topic kx 500 sumo.
btw nice ride that kx!!

but do you like that setting?,
im pretty pleased by the torque and accelleration with 15/42
wheelie in 1/2/3/4 and abit backwards leaning
mine,s tuned also by flowing the ports and fmf Fatty with main jet 182 euro.sizeno.#
it rips your arms off if not fully concentrated.......
are you running a bit richer mixture for sumo ?
like i do for the bit more lubrication at high rev,s.
i set mine so that it,s like a non stop pulling rocket with that lil, richer mixture
and the plug looks good ,a bit grey next too darkbrown
how,s yours looking if your settings r,like mine?
keep the green side up and succes at lundaracing track!!
