Changed petrol all I get is a half hearted start then what sounds like a miss fire a big phut sound and lots of cursing from me some times a kick back ( but now my legs are like a prop forward it's no problem )and as a last resort a cuppa followed by the sound of the garage door shutting
Any other suggestions greatly received

Are you getting a good spark?.You will need someone to kickstart the bike for you.Inlet rubber from the carb ok?Coil checked?.There are some multi-meter checks I have seen in the service manual for this.

Well good news reset timing got bike started for about 30 seconds then it stopped kicked it again then another 20 seconds then nothing has petrol in the carb when i dismantled it any other ideas what to try next got spark but plug seems to soot up

I had very similar symptoms on my bullet a couple of years back. Turned out to be the condenser.

Leave the garage doors open-------- maybe someone will nick it !!--LoL !!.......Of course a real insult would be that you leave the garage doors open overnight and in the morning someone's left another one alongside yours !! ( GLUM )

OK--- seriously now, if you have soot on the plug with so little engine running then partial flooding may be the culprit..........Can you borrow a same carb that's known to be OK and just substitute it ??.......Float level correct ??..........I notice you originally said that you changed jets back to standard Mikcarb, and that all this started after you re-built the bike....So can you give us a description of what was involved in the re-build and the exact set-up you have at the moment please ?? If the bike was running OK before the re-build then obviously you have made some sort of a fundamental change to something in order for this to happen..........( Logic Mode c/o Mr Spock )..

Thought about putting on a sign steal me know !
Rebuilt engine rebore to +40 bought to do up something to fiddle with saw on u tube might be wet sump so drained that
No used to bullets so still learning .just annoying last bike I rebuilt started 1st time but it was a BMW
Also I have noticed oil level dropped since filling but no sign of leaking anywhere strange ?
Probably something really stupid

So. Changed that condenser yet? It's been mentioned by three different people now. Don't assume it was assembled correctly. The last bullet I built had a 6v condenser fitted to a 12v bike. It would start and idle but die at the slightest sniff of throttle.

If you didn’t fill the timing chest during the oil change then approx 200cc of oil will be missing from the oil tank because it’s ended up in there.

I think I would be changing s/plug-plug cap-plug lead- coil- condenser, in order of cost lowest first, as it does seem like an ignition problem, I would double check the float level and the needle valve it controls to be certain both of these are set and operating correctly.
