Question about 1987 Honda CBX 250
I have a 1982 Honda CB750C that I bought a while ago. it was a mess, but have been rebuilding it. It's not my first rebuild, but I am having troubles getting it to run.
I seem to have a problem with the carbs> I have taken them off and cleaned them all the jets and needle jets the works I also replaced the fuel lines between the carbs. After installing them on the bike I can't get it run roght at all. It runs weird, backfiring sometimes and then not stating at all others. I can tell that sometimes i'm only running on three cylinders. I have tried adjusting the pilot screws to a neutral spec ( from maunal) but that didn't seem to do anything.
I got nothing left and my car just died so I'd like another form of transport. any ideas what this may be?
You MUST synchronize the carburetors.
It is a task that involves some special tools (carb synchronizer)

Sounds almost like a timing problem. Have you had the head off? Has someone else?
You should be able to check the timing from the maunal. Valve and ignition.
If it's a fuel problem and it's popping through the exhaust it's too lean. Be sure you have the proper fuel filter and it's clean.
