Bantam / Re: 1968 D14 Bushman headlight shrouds

Hi
The parts books use the same drawing and show the same part number (97-2593 & 97-2597 for right and left) so they should fit. The D10 Bushman ears donít though as theyíre for the lightweight forks and have a different number (90-5321/2).
Hope that helps.

That museum is in Nicosia and is well worth a couple of hours! A really interesting collection of Ďbikes, when I was there I got chatting to the owner and got some of the back story to the exhibits. Even the wife enjoyed it!

Hi Phil,
Reading through again have you had a go at your carb with eg ultrasonic cleaning?
I bought a small ultrasonic cleaner off EBay and itís just about big enough to fit a dismantled Monobloc. I still also go back to older methods like soaking in vinegar to get things clean too. Itís a judgement call as to how long you leave things to marinade but it can be very effective at clearing out the tubes.
I know others resort to boiling their carbs in a washing powder solution!
A last resort is to drill out the pilot passageway as espoused by the Bushman.
Regards.

Hi,
Have you seen ďBushmanís Carb Tuning secretsĒ?  Itís very informative and easy enough to folllow.

Click on the link to the pdf and print it off for some bedtime reading!

Iíd get in touch with them, that sounds too long jus5 to change the owner details on a V5.  If you were trying to re-register a bike it might be different.

The seals are always worth checking for wear and/or incorrect fitting but that does involve a full engine and gearbox strip.  Before you go down that route itís worth double checking the ignition especially as you say it doesnít even cough.

Sparking outside the cylinder does not always equate to inside the cylinder. Ensure the plug cap does not have a resistor in it and swap out the plug for a trusted genuine one. As you say replace the condenser, check the points themselves are working as they should. All normal stuff.

The wiring, especially on D7s is complicated as the switching tries to match generator output to load. The different wiring harnesses look the same but arenít. It might be worth hot wiring the ignition ie by-passing the ignition switch completely to see if it makes any difference.

Then ..

Is it a ďmagnetoĒ ignition ie spark direct from the coil on the left side of the engine? If so you could rig up a constant loss external coil and battery to see if the bike will start, if it does then suspect the internal coil or the magnetism in the rotor (can be re-magnetised by Villiers services).

Next ..

On these earlier engines with generator and points on the left the keyed shaft can turn in the crankshaft flywheel as a result of a seizure. If this has happened then the timing will be out. (The rotor will also be out of sync with the magneto coil which will also affect the spark). To add to the confusion the D1/3 crankshaft assembly looks the same as the D5/7 assembly but isnít as the angle of the woodruff key slot in relation to TDC is different. This can all be checked by removing the left hand side cover and the generator stator plate and measuring the angle of the key BTDC. The central bush in the stator plate is also suspect, if very worn it will allow the crankshaft to whip and affect the timing but this will usually only be an issue at higher revs.

Or ..

If the points are on the right the cam is not keyed to the shaft but is held by a taper.  This means that itís possible to have the timing 180 degrees out.  Worth checking.  These bikes have an external coil so this can be swapped out to check.  Watch out for the low tension feed to the points as it runs under the engine and is very vulnerable to damage.

Bantams can be (are?) infuriating but do start reliably once set up properly (mines a first or second kick starter).  They seem very simple but things are of course fifty years old, Iím sure a methodical approach will have things running.

Courage!!

Hi Mike,

It will depend a bit on the type of Bantam you are looking at. The early engines, up to D7, are very different in the ignition department from the D10/14/B175s. If itís a Bushman it will be a later engine.
Any pictures?

Hi Otto,
Your English is very good, but the frame is a mystery to me at least!
I hope you soon find out what it is.
Kind Regards

Hi Griff,
Did you get anywhere with the paint?
ďRS Motorbike Paint LtdĒ  list the Bushman colour scheme on their website, might be worth a try?

Thanks Adrian,
I thought there wasnít much else to stop the oil from leaking out. Iíll try with the PTFE tape first plus some 15SAE oil.
Now, where are those springs?!

Finally Iím at the stage of rebuilding my C15 forks (for my Bantam green-laner project). All back together, well they will be when I find out where I put the springs! Oil seals fitted, stanchions a nice sliding fit.
Iíve got two questions:
What grade oil should I use? and ...
Is it advisable to wrap some PTFE tape around the seal holder threads?

Thanks

Thanks guys,
Iíll have a go at the fuelling this week and report back.

Hi Bluebell,
Itís a small bore exhaust. Itís on the original Wipac points but with a separate coil ie not magneto.  The electrics are simplified with full output via a reg/rec to charge the battery, still 6v though.
The centre bush on the generator is good.
It is a small spigot tap, Iíll look at that first I think.
Could a silencer in need of a decoke bring these symptoms?
