the starter doesn't really work (most of these yamaha's have this problem)
No problem popping the clutch and starting it that way, or keeping it started. Just kick starting. Even after it's been ridden for awhile it's still hard to re-kick start. All electrical works great, no engine problems only issues are with the kick start. Typicaly takes 20+ to finally get it going, and requires me to play with the choke as well.
1977 Yamaha xs400 4,500 original miles. well maintained.My bike is becoming harder and harder to kickstart. Any ideas on how to fix this?
its got no compression. you have to play with the choke cuz its got no vacuum, cuz is got no compression. if its a 2 stroke, the crank seals are shot too.My bike is becoming harder and harder to kickstart. Any ideas on how to fix this?
maybe you should start thinking about re ringing sounds like the compression rings are goneMy bike is becoming harder and harder to kickstart. Any ideas on how to fix this?
Could be a bunch of things, but I would start with a leak down test. It will tell you a lot and is worth the 100 bucks if you have a compressor. It can tell you if it is the rings,intake or exhaust valves leaking. This is a good link to start with!

Only one new carburettor? Generally you should replace the set (i.e. in this case both of them). You must have the first of the 400s. Mine was the same year, but last of the 360s. Never had any problem with the electric start, even after tens of thousands of kilometres. Sounds like it just needs a proper tune-up; timing, and carbs adjusted.
Actually, just remembered; on mine, there was a vacuum hose that ran from one of the carbs to the fuel petcock. It came off once and caused similar problems to those you describe
