Hey everyone bad problem but interesting answer

My bike which is a 2004 Vulcan 750 with 11,000 miles on it the problem is that I can't seem to get her running right she runs good win cold but then starts missing win she gets warm up I've had my local bike shop take carbs off clean them set them and still have the same problem now they tell me they need to do a compression test and I haven't heard any thing from them yet.I left the bike at the shop so I guess ill hear something soon does any one have any suggestions of what they think could be the problem? ?? Starts missing at about 2,500 hundred rpm and on up from there but what's weird is I can tell its missing win I'm riding the bike? ? New spark plugs ngks just changed trying to help the problem but it didn't change anything

Does it miss under acceleration, when steady, or both? Sticky or faulty choke mechanisms can cause missing from a rich condition, and a clogged pilot can cause missing at steady throttle/RPM. Hard to tell really, sounds mixture related to me.

That problem is consistent with a float being too high or stuck choke. Either one of these should have been caught during the rebuild at the shop. You might want to check the float height yourself. Both of these problems can be troubleshot without removing the carbs.
