3000 RPM hesitation

[teck_mountain]

Hello

Okay, I think I've gone through the break in process on the new top end. Using no oil and generally running well. However, I have a hesitation at 3000 RPM. Not much of problem on the highway but very noticable in town. Seems to be a bit worse under more load than one rider.

What would the best way to fix this?

i had the same problem on one of mine it turned out to be a blocked jet in one carb.i did not take carbs of to sort it;
removed the airbox;
start engine and let run till warm;
rev engine to 4000th revs;
then block of one carb at a time while keeping the engine running;
the suction of the engine sucked the crap out of the carbs
no problem any more.
