Jetting problems

I know it's not a real thumper but I'm hoping to draw on the wisdom of the group. My son has a klx 110 that is stock. I have tried every combination of jetting and ended up sticking with the stock pilot 38 and main 78 (stock main is 80) with the needle shimmed with 1 small washer. This has given me the best results but when cruising at constant throttle both closed to 1/4 and 1/4 full it will hesitate every few seconds. The carb has been rebuilt. Like I said I've tried all different combos of leaner/richer jetting and still have this hesitation. Does anybody have any ideas? Could the slide be worn out? Throttle cable just wore out so it has seen some use. Thanks in advance.

To my kids and I regretfully selling our beloved KLX110L. I remember shimming the needle on an otherwise stock engine and it ran like a firebreathing wheelie machine. Have you looked at the plug? Maybe clean the carb again with compressed air/cleaner. Try a thicker or thinner shim? Pilot and main jet should be O.K. You could buy a new carb (they're cheap) Just throwing out some ideas.

Thanks stevo. I will probably end up trying some thicker shims if that doesn't work I'll spring for a new carb
