84 gl1200 fixin

Yesterday I replaced timing belts and diaphragms. Once all assempled had no leaks so fired it up kinda sounded rough. But fired up on the first start. Noticed when I brought the choke all the way off it sputtered and wanted to die. So quit for the night, this morning went out and cranked it right up, same issue still with sputtering. Question is could new diaphragms not be positioned correctly since they were a little deformed during shipping causing issue? Gonna put old ones back in later and see what it does.
If its timing related can i just pull radiator off and timing cover tonadjust or do i have to pull front oil/waterpump cover off to? Thanks

Vacuum Leak -

Hey Aron - Has your bike run properly since the carburetor rebuild ? It is very important to synchronize the carbs any time they have been disturbed.

Use a very light spray from a can of carburetor cleaner around all the air fittings and clamps to help determine if you have a vacuum leak. The rpm will quickly jump up when the source of a leak is sprayed.

Don't start taking anything back apart pertaining to the timing belts. Usually a TB install is fine.

To answer the timing check question, you do not have to remove the oil pump/water pump cover to access the timing belts.
