I have a 05 750 vulcan. I just took my carbs off for a cleaning. the bike would only run with the choke on.
put it all back together and now it idles great. but i can't get pass 4500 rpm. it just breaks up and bogs out. set the air screws 2 turns out. I did not sync them. could that be it? I did not have this problem before cleaning.
When I had both of the carb bodies off of the float bowl assembly for cleaning, I somehow managed to flip flop the carb bodies on assembly.
I noticed when the choke cable assemby came in from the wrong side of the bike. I just flipped the choke assembly around to face the right way. Is that OK? There is no primary carb is there? Aren't they identical?
I noticed that when I put it on the side stand the bike idles up to 2000, pick the bike upright and it idles nicley at 1400, lean the bike to the right and it starts falling off and eventually stalls. Pulled the plugs, front clnder looks good, rear are black as night. like carbon fouled not fuel.
Also I did the coastering mod at the same time. I blocked off the reed valves and plugged the vac line on the right side carb. I left the rest of the valve body under the seat with the rest of the lines still hooked into it.
What is the valve under the oil tank? it has vac lines going to the gas tank and to the surge valve under the seat.
Where can I get a service manual online?
