Hi All
Before I have a white and blue bonfire I thought I would post my frustrations here to see if anyone has some advice I can use. I have a mechanical background and have rebuilt half a dozen bikes and do all my own servicing, but this thing is giving me the sh#ts!
PHASE 1: It is a PIG to start (can take 15-20mins), however once it is going and get it warmed up it can be ridden and runs ok (still a bit rough). As you kick it over it fires for about half a second then stops, just enough to keep you interested. After you have be kicking it over a dozen or so times the only way I can get it to start is give it the slightest bit of throttle when it runs for that half second. Problem is this is very hard to get right and usually takes quite a few tries, on the odd occasion you can catch it.
PHASE 2: Once going you have to hold the throttle at 1/2 to 3/4 otherwise it just dies. After about 2 to 3 secs from running it tries to die completely and you have to wack the throttle wide open to catch it from stopping. It needs approx 4-5mins warm up before it can be ridden without stalling when you put it in gear.
I have replaced most of the electricals and checked the carby inside and out, it has a brand new bottom end and crank seals, plenty of spark, plug is wet, I have isolated and tested the kill switch.

ANY advice I would greatly appreciate.

Manual says BP6HS but when I got the bike it had a BP7HS in it. I changed that out for the manual spec (BP6HS) when I gave it a service. However when the issue appeared I tried the 7 back in the bike but it gave the same issue. So today just for kicks I went and bought a new BP7HS put it in and the thing runs like a top second kick! Bit of a re-tune and it purrrs like it should and goes better than it has ever gone.
