cheap and easy to repair.

This is good advice. Personally i would do a major ( annual) service plus install new needles and needle jets. It will cost less than £10 for teh parts and can save a lot of problems. These bikes should not be difficult to adjust the running to be reasonably smooth ( For a TWIN), if it is difficult, something else is wrong (diaphragms suspect no. 1 ).
sychronise the carbs by eye, then road test. Run at the speed and throttle opening you will be spending most time at. Then adjust one of teh carbs cables a small amount. retest. if smoother repeat. If rougher adjust cable other way . and retest. Eventually you will dertermine best place. It may not be as good at other rpms or throttle openings. but that is teh best you can do, live with it.
