jetting...........

Post by qkenuf4u »

ok ive read/printed out/mulled over etc.. all the jetting stuff on this board but havent seen my answer yet...

ok here goes..
92 cr500
new top/bottom end with 10mins run time
wouldnt idle/smoked (not huge amounts but enough)
had pretty much stock jetting
carb cleaned
FMF FATTY (GNARLY NOW )
exhaust isnt seale up just yet (waiting on stove rope to seal it up)
so i found a place in town that actaully has pilot jets (KEIHIN) and picked up a 42
put it in, started after second kick
smoked a lot less
air screw is set at 1 1/2
idle is set at 8 3/4 turns out
will idle for about 5-10 seconds then blubs out
my question is.... is the 8 3/4 turns out on the chock knob showing im to lean on the pilot (bump to a 45 or so ??)
the air screw is pretty sensitive now and it will change it going one way or the other but not enough. i want to get that choke knob closed up some from what im thinking....
ok so we got
600 ft elevation
75* dry day
170 main
42 pilot jet (was stock 55 but way to much fuel)
1 1/2 slot on needle (small washer under E-clip to shim needle)
1 1/2 turns out on air screw
6.5 slide
needle #R1368N (little S under that number)
91 w/ 927 oil
way less spooge out of pipe
when i start poooping money ill move onto the PWK but for now i have to work with what i got... :roll:
