Very slowly getting everything from 675 back to 583, but before I get too far - will anyone volunteer their jetting info please, so I know if what Ive got is vaguely close.
It was running 148 mains, 40 pilots and the needles were 4th from top (cant see any markings on them)
So its only about 10% bigger than std jetting, but I have no idea what the dynojet sizes are, or how different the 675 and 583 ended up.
All info gratefully received.

Phill mine was lean after converting it back to 583, however i did advance the cams too. Strangely enough when it was jetted after the bb was fitted it was too rich.
The mains have remained the same from what i recall, just had to raise the needle a bloody long way.

Phil,

I chnged to 146 main jets, legft everything else same as 675 Dynojet kit.

Running 900 headers and Hi Level 900SL open pipes.

Works for me...58hp at the crank, nice curves.

Doesn't idle though...
