Bike year & model =2001 ec300 new pwk 38 carb
Temperature (degF) =50 - 90
Elevation (feet) =1500' - 4500'
Main jet =168
Pilot jet =38
Needle & notch =cck #3
Air screw setting =1 + 1/8
Throttle valve/slide =8mm slide cut
Results:A used bike new to me. After much jetting frustration, I concluded that the needle jet was worn out.
The only part in the carb that wears out and you can't replace it. New carb!
I'm looking for best mixture delivery between 0 and 3/8 throttle. With this receipe,
the power generated as soon as you crack the throttle off its stop, is awsome.
Tire shredding power from sub-idle in any gear, with smooth hard pull to good
over rev. The cck needle didn't work well with the stock 7mm slide, but nothing i tried
did. Idle, very sensitive to temp and altitude changes. Usually 3lt fuel consumption
for an average 2 1/2 hr technical ride. This is a work in progress, but theses results
seem worth reporting. Any tips, hints, or critizisims, will be welcome.
