Yeah, I've had similar symptoms once with an old Mini and once with a Harley - both were a dodgy coil!!

Hi from Houston Texas by the way.  I grew up in Ireland and moved to Scotland when I was 18.  I lived near Edinburgh for 18 years before moving here.  I return to Ireland every year so me and my dad can ride about on our old BSAs.

Hi ya, never been to Ireland, but was living near Edinbugh upto 6 Months ago, Livingston to be exact!
Lets hope its fixed tomorrow.

The sign of a failing condenser is that it works OK when cold, but fails as it warms up.
After it fails the bike stops running , the condenser then cools down which will then allow the bike to be started again, only to stop a short time later.

Well, its Thursday both sides of the pond now, replaced condenser, re-jetted from 110 to 120, new air pipes, and its still the same!
The importers are sending up a new coil, if its not that, I dont know.
Valve push rods are set right, no play but just spinning, I am totally lost on this one!

Hi
Damn!!!!!!
Bought a 500cc bullet about a month  back.
 I have exactly the same problem.
Runs ruff(backfires lots) and dies after a few minutes.
Have checked timing and valves.
Drained the tank and checked the carb,seems ok.
Have gas to the carb.
Replaced the rubber hose between the carb
and cylinder(has a K&N filter on the other side)
Have a condenser and coil on the way.
I just want to go for a ride
Thanks

Hi Jeri,
Have you got a bigger jet from standard as you need one for a K&N or after market exhaust.
Standard appears to be 110, I got sent a 120, I have seen them on ebay upto 130.
I have a new coil on the way, if thats not a fix I don't know what is!
A tip: when changing the condenser, take a bit of time to shape the connector to the shape of the bolt as there is very little room, not much thread showing and its very fiddly on re-assembly.
If you can push and hold the bolt head in place on the back plate, this will give you maximum thread the fiddle the nut back on, and make sure the tag that the nut screws up against is not touching the back plate.
When you have done it turn on the ignition and check that your amp meter flicks, it will save you a lot of time if you got anything back in the wrong order.

Hi Scot
Ya, know when I had the carb off I did not think
to check the jet size(just to see if they were clear)
I think this weekend I will pull a coil off another bike
(still waiting for a new one to show) and try that.
Thanks for the tips on the condenser change.
I have not reached the end of my driveway with this bike and I
am really getting frustrated(ok my driveway is about half mile long).
Good luck with your troubles.
Thanks
Jeri

Scots Bullet

I am running a 120 main with standard air filter and the stock exhaust with slightly drilled baffling.
My carburation seems ok for that configuration. I tried  the free-flow S&B air filter on the same jetting and performance was very poor with no torque at low revs and difficult starting, so went back to standard filter.

That's exactly what I have, notice I didn't say 'that's what I'm running' 'cause it ain't!
Only difference is there is no drilling in the baffles.

I bet its the coil!!

Maybe we should have a poll?

I would agree on this especially since most of the problems happen when the bike is warm. Most electrics operate poorly when heated.

As the only 'electrics' left to change is the coil, I think laying bets would be more appropriate than a poll!
I'll be bl**dy fuming if it is the coil as thats what I said in the first place, nearly 2 weeks ago when the symptoms first showed.
And if its not the coil?

[Leonard]

Maybe I missed it but if the battery isn't putting out at least 12.8 volts that could be the problem.

[Bath Bullet]

After standing, battery tested at 12.8, trickle charged to 13.18, charge on bike with engine running 15.8 max, new battery 2 weeks ago.

Have you checked the Bullet connector 10 inches from the points,that one is well known of causing all sort's of problems.Best soldered,permanent.

Yep, done that too.
