How do I correct Surging Problem...?

Hi there I have a '96 DR350SE with 12 000kms on the odometer.

I had my first ride on this bike today and I'm having a 'surging" like problem. At low to near high throttle position the bike surges, not like a bucking horse but very noticeable, (ie: the ride is not smooth either when I accelerate or when I'm trying to hold speed). When I give it full throttle it smoothes out and the surging goes away until I drop the throttle back. This tells me it is something to do with fuel delivery (but I'm a newb at such things).

I had Jesse in Grant Falls OR put in the larger jet and check/clean the carb, I cut out the air box, replace the stock foam air filter with a Uni foam filter, put in a new spark plug, put on a Acerbis fuel tank and adjusted the valves.

Is my bike running too lean at the lower RPM's or.....?

How do I smooth out the throttle and get rid of the surging.....?
Other than that I love the bike, lots of power and very fun off pavement, makes me feel like a superstar off pavement compared to my Wee!
Thanks!

It seems to me that you had the right guy set up the carb, he should know where to set the needle and what jets to use. Brians advice is good. I'm thinking that you may need to look for vacuum leaks. Check your inlet boot and connection and all vacuum hoses and connections. Good luck.
