the sig mods list this as a 35mm airstryker
personally i'd only run a 35mm on a ported bbk,
others run it, and larger, but seem to be more concerned with all top end "powaa" at the cost of bottom and mids
what needle is in this thing ????
the needles most of the keihins come with are usually way too rich for our bikes
on my 34mm pj, a switch from a "k" sumthin, to a "dgh" needle cured a whole mess of jetting issues for me, others are running the "cel" needle
report back with what needle is in this, and is the float height to spec,
i think that can be found on here......
Keihin ATV Carburetors
write down your findings, a call to /\ carb parts warehouse ended all my jetting woes on my 34mm pj
which by the way is running .............
45 pilot
155 main/162 in colder temps
dgh needle
you shouldnt be much, if any, richer jetting than mine,
as your choice of an FMF pipe is holding you back, versus my left bend F7
i'm gonna guess your too rich on the pilot and needle, and those are also effecting the main
assuming the float height is correct.......
what airscrew setting gives you the highest idle ????
under 1/2 turn out = smaller pilot
over 2 turns out = larger pilot
it must be certified leakproof,
the float height, pilot and the correct needle, before trying to jet the main, then plug chops to confirm what each jet is telling you "rich or lean", not just blindly jump up and down
