Stock 350 R:-
Main jets; 180. Pilot jet; 25. Power jets; 25(R) & 25(L) Shocked

It's well worth converting to F2 specs which means removing the collars in the downpipes and the following carb modifications. (The 350R carbs had lower size jets to cope with the low quality Brazilian fuel).

Main Jets; 185. pilot jets; 27.5. powerjets; 60(R) & 65(left)

thanks drewski for input about 350r carbs. took friends advice and dropped needles a notch which made big improvement. collars in down pipes not apparent so i guess someone took collars out,made it unrideable and passed it on. if i can find any f2 brass bits i shall put them in. nb do u no if ignition timing is same or similar.
