heres that long overdue jetting info-
______________________________________
1975 RD350 (.040" over)
needle 5Dp7, 3rd position
Needle jet 169-p0 (spray bar cut to 2mm)
Main 180
Pilot 30
Throttle valve 1.75
Dial-a-jet set at leanest
Altitude: 7000 ft, temp 50 degrees
DG pipes, K&N with y-tube, boyesen reeds, enlarged
reed cage
Comments: I also increased the compression so that it
is about 150 psi at sea level, but at my altitude it is more like 130 psi.
The Dial-a-jet is like an adjustable power jet. Good for top end and augmenting
the main. Stock timing, big coils and electronic ignition with plug gap
at 1mm. Bout 45 mpg. I cut 1.5mm off the bottom of the stock throttle valves
to take it from a 2.5 to 1.75.

350 a/c, running premix
Be careful I used 280 mains
Q-2 needle jet
stock needle in middle position
air out 1 3/4 turns
#40 idle/low speed jet
and at daytona I would go up to 310 and on warm moist
days I would have in a 240 main And then with other engines I would use
something like 250 mains
0-4 needle jet
stock needle in one low from middle
air screw out 1 1/2 turn
________________________________________________________________________________
The RZ350 has 21mm float height(I had the wrong float
needles in there!) and
has 160 mains with the 1AU-00 1986 Canadian carbs and
pipes. All else un
changed.

SpecII jetting recomendations (from the forum)
With accessory air cleaners (RD350):
Main jet is 220. If the air cleaner is oiled, it can
drop as low as 200 mains. Needle is on the Second notch from the top. Airscrew
is a 1-1/2 turns out. "You may have to play with the airscrew and needle
if it runs rich down low".
With Stock Air Cleaner (RD350):
190 main jet (with cap off aircleaner), second notch
from top, airscrew at 1-1/2,"You may have to play with the airscrew and
needle if it runs rich down low".
Timing set a 1.8mm BTDC instead of 2.0 mm BTDC.
