Problem...

Sounds like the carb is lean and not enough pump shot or the squirters are wrong size. What size squirters are in it and what are the jet sizes. Large cams and converters like lots of jet.

Its got 68s in the primaries and 72s in the secondaries for the jets. I haven't changed the jets from stock, could be an issue. The carb has been rebuilt, and the guy did it right back to stock stuff. As for the squirter, its all stock per 650 SD. The accelerator pump cams seemed to be sized right as it does squirt any time the throttle is rolled open, so it may be a squirter or jet issue.

I'll lower my idle down to about 850-900 tonight and find a jet pack to start tuning. Thanks a lot, any other input still welcome.
