You have most likely checked this but.... is the fuel tap turned to “on”

Hi guys------Fresh or stale petrol or some water in tank ??( Been off the road during Winter ??)---Empty the tank and re-fill with NEW petrol---Remove air filter----make sure the "Fuel on" position actually shows a flow of fuel----New plug of the CORRECT grade fitted -----no flooding from carb. overflow pipes ----try again.

Often a poor spark at the bottom of poor starting/running. Duff condenser would do it. As would a duff plug or a bad battery earth connection. Was it running well before?

Loosen fuel-filler cap and see if that makes a difference.
See if the rubber to the carb is split?
I'd echo what the others say, and stress Alan's comment of a NEW... not just cleaned ..spark plug.
How long since the last service? It could well be worth putting those new items in for a try, eg points etc, then at least you eliminate them AND it might work.
Is the "choke" in the correct position?

(I recently had massive running problems with my car and it turned out to be the NEW condenser I'd put in was faulty....)

Good luck, Chris

Worst case scenario is that you'll end up with legs like Popeye's arms --LoL !!.....Which should be a good talking point down at your local pub, and may even get you a free pint or two !!

I forgot to add}--- Before you do any of those Petrol-involved checks, ie}--- no vapour at or near your bike, check the quality of the spark on your NEW plug.......You should hear a nice, well defined "crack" and see an intense blue spark at the electrodes....If it's barely audible and shows a weak, redish colour then start checking all the connections, followed by a new condenser (cheapest option)--- then maybe consider the coil ?? ... My Bullet '65 came with a Bransden Electronic ignition system ( which according to receipts must be about 8 years old now ) and a PVL coil......

Anyway, do let us know how you go on with it. Hope all's well; otherwise I'm sure more useful suggestions will follow.

Is your bike a model with a left and a right kickstart?
Otherwise, how come both legs are the same... I always wonder if professional tennis players get one arm more muscled up than the other?

Hi if your bike has points ignition check that there is no lift in cb cam, had similar with an iron barrel problem was crookbbushes in dist body giving variation in points gap, if an older model you will have bushes newer ones had ball races, ended up fitting a grease nipple on top of dist houseing.hope this helps.

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 H

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.

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.
