Dellorto carb advice (SM570)


Recommended Posts

Trying to adjust the idle and mixture on my 2004 SMR570 - it has a Dellorto carb with the primer system (no choke). I guess the big screw is the idle and the little one to the left of it the mixture? Is that right, or am I miles off?

Any advice will be very greatfully received. Thanks in advance, Andrew 🙂

Can anyone help with the correct mixture screw setting? - in my manual it says "the standard position is 3 revs that is to say backwards as regards the full closure position of the screw". 🙂

I guess that means three full turns out from fully tight? - just want to be sure

While I think of it, does having the mixture screw in further lean out the mix? When I got the bike running at tthe weekend it seemed to be running a bit hot, suggesting a lean mix. Just fast idling on the sidestand for about 5-10 mins was enough to get it coughing out a bit of coolant
