Fellers I posted a thread a few weeks ago about a PMA and reg-rec problem (charging at 15.4v turned out to be blown reg-rec caused by the solder failing on one of the phases of the PMA). I thought I had it fixed the problem. Put on new battery, but ran with the capacitor. The wired in...

Fellers, any ideas on this leak? I turn on the fuels and the left carb starts to drip fuel from the UNI filter. Took filter off and see the fuel is coming out of the the pilot inlet (as named in the Carb Guide). This bank of carbs is 78-79 BS38s, and the pilot hole is the lower left of the...

Fellers I have never had so much trouble, and some weird stuff going on. Recent PMA failure led to reg-rec blowing and battery fry-up. So, Fixed it, and I'm on borrowed 3-phase reg-rec until Hugh's replacement gets here. While all that was going on I tinkered with everything trying to...

Fellers I found the source of my burnt-out battery and regulator-rectifier - it turns out that the source of the problem was the PMA. Symptoms - 15.4-16+v measured with wired-in voltmeter and multimeter. Diagnosis - regulator part of the regulator-rectifier not working. I exchanged emails...

Fellers I am researching rectifiers because mine is turning the AC voltage to 15v DC at around 3000 revs. I understand that the solid state regulator-rectifier has six diodes in there - I am still learning, but is this a bridge rectifier or a dual bridge rectifier? Secondly, is it the...

Fellers My voltmeter arrived all the way from China. Recommended by reviewers on eBay, so who am I to doubt - well, yes, I do doubt, so I got two of the things to double check. The bike has been running very poorly, progessively worse. Thought it was the carbs. TwoMany said 'Might be the...

Fellers I have a second bank of carbs I want to swap with the carbs currently on my bike to try and find a fuel supply fault. The second bank has a fuel inlet nipple missing. Anyone know where i can get one? If possible I will try and avoid the ridiculous charges the UK puts on stuff coming...

Fellers Everything has been working fine. Cam chain, valve clearance, timing all in near to perfect order as I can get them. I have read the carb guide several times, and just flicked through again. I cleaned the carbs and set: jets as per advice from 5twins and now 2-1/4 turns out on the...

Fellers, My second project, the E-Type Banana is sitting there, engine rebuilt, waiting to see if it will fire. I have a Boyer for it, but no PMA yet. Rotor/stator is in there, though, so I thought I would have a go. just need to wire in the correct regulator/rectifier, here's the...

Fellers, Everything, as best as I can do, is properly set-up - can chain perfect, gaps to spec (checked and rechecked) the timing (Boyer) is spot on, floats set to 27mm (BS38s), jets 137.5 and 30, screw 2 full turns out, plugs light brown. When running the engine is purring really well. I...

Fellers, There are many posts about mis-firing, kick-backs, poor timing. Here's a little tip that might just be your problem. I put new HT leads on the bike today - one of the old ones failed last week and the juice arched to my leg (not pleasant!). Before it failed the bike was running...

fellers Recently my 6 months old battery fried. Now holds a steady charge of 10.80 v,olts, so that indicates one of the cells is shot. Goodbye battery. Its under guarantee, so i will pick up a replacement. I checked the regulator/rectifier. Multimeter says all is good, diodes open one way...

Fellers, I have just finished a three day tour of Wales with 60 other guys, a charity event. The Flying Banana made it the 575 miles up and over the mountains and back safely. The week before I left I did the cam chain, valve clearances, re-did the Boyer ignition, cleaned the carbs, cleaned the...

Fellers This is my wiring diagram. I have blown three 10amp fuses to the light circuit - that's the one on the extreme left of the four 10amp fuses in the fuse box. You will see that line takes power to the headlamp switches and lamp itself, and then completing the loop at the tail light. No...

Fellers Weeks of running absolutely smoothly, then a 75 mile ride. Accelerating 35-45 a sudden blank spot as if someone had switched the power off for a second. Bike continued back to smooth. It happened on the ride three or four times in the first say 20 minutes of the ride. What could it...

Fellers I had these RAMHORN handlebars on my BSA A10 back in 1977. The bike disappeared. I have been on the look out for any sign of it for, let's see, 36-37 years, nuttin' (could it have been the one-armed man?). Then a couple of weeks ago the bars turned up on eBay. I bought them, and they...

Fellers There are no tabs on this custom frame to limit the steering - help. I don't intend to go around bends with my front wheel at 90 degrees. I will need to weld on some tabs at the correct place. Does anyone have a picture handy to give me an idea of positioning of the tabs? Much...

Fellers, take a look at the pics. I want to lower the engine. I can change the aluminium brackets, so that's no obstacle. What I want to do is remove the fixing points on the frame that support the bolt through the lower engine. Then I will put them (or new ones) on the underside of the frame...

Fellers Would some kind friend please tell me if the speedotacho assembly sits on top or below the top yolk Secondly, I am waiting for my Vernier calipers to arrive, but in the meantime does anyone know the internal diameter of the yoke holes to attach the speedo/tacho assembly? I want...

Fellers If you remember the Spider Bobber project that took up a good deal of the Smallest Workshop in the World I can tell you the engine is now stripped and rebuilt, new clutch, hydraulic clutch, about to order a Hugh's PMA, Boyer ignition, and helicoil one of the right hand side casing...
