Now realised why this is how they fitted the Monobloc to the 65-67 Lightning from new. I could not see the wood for the trees on the call but if you look at the Monobloc again in your garage you will see why - there is an important thing that needs to be got at on that inner side, I've even had to get to them myself so I should have remembered. Essential for tuning of the bike when warmed up. Yes it makes the tickers fiddly to get to but I guess the lesser of some evils. (The Just Beeza forum have just pointed it out and and agree owners like your mate have probably switched them around).   |

I had a chat with Mr beesa about this he told me they designed for the concentric but weren't out till 67 so they put the monobloc that way cos the float boles stuck out.bsa gave the option of fitting concentric carbs when available.in the uk most were turned round cos it was stupid

Not on the Lightning. The concentric appeared on them in 1968, they only appeared on the Spitfire in 1967. The 65-67 (pre concentric carb) Lightnings with the float bowls on the outside were not how they left Small Heath, no matter what the BSA expert at the local bike meet thinks. Even the parts book shows them in the order they were fitted.  |

Nick why did bsa give new owners of lightnings in the states the option of having concentric carbs when available fitted to there bikes they f up why do they not fit the concentric that way plus the monobloc has a big design floor that make monobloc not suitable for modern motorcycles of the day.have you wondered why the extended float bowl became well you do not if you did i would not be wrighting this,as the float bowl is on the side on the mono if you bank for a certain length of time at a certain angle you lost power through no fuel so fitting a extension gave you some more time.the monobloc was not fit for purpose thats why the spitfire was fitted with a gp carb that was not fit for purpose on a road bike and then all were fitted with concentric when they became available. All bsa did nick is make obsolete items fit .so they could move there produce. Enny body that ran one of these bikes and not had it as a ornament knew it did not work and bsa knew it

Mark I told you how the Monobloc carbs were fitted on my '67 Lightning and you immediately said that they were incorrectly installed. All talk of 'ornaments' and even Concentric carbs aside I think I have shown you enough credible information to at least agree that the carbs fitted to my model of bike were correctly installed. The Concentrics were simply not available in volume to put on the Lightning in 1967 hence why the Monobloc was used in that year....they came on the Lightning in 68 as I have already told you......USA or UK it was all the same - the bowls were fitted inwards from Small Heath - enabling easy access to the fuel / air mixture screws. I understand how you may find it inconceivable for them to be fitted this way around especially when so many people have switched them for easier tickler access. I have to say that the ticklers were fiddly to get to but certainly not difficult or impossible by any means. The bike below is yet another member's on the BSA facebook page And on that note - I think I'm carbed out.  |

Nick you are not listening I am not disputing thats how they came from the factory but riders that road there bikes turned them round. How many times a day did you adjust the carb to flooding to start and ease of access the guy that has gave me the info about my a10 engine build was a bsa trained technician said when they came in for there first service they wanted the carbs changed round.they were not practical as bsa fitted them..1 you can see when you have primed the carb 2 ease of access to the float bowl 3 ease of access to the fuel filter.to how bsa fitted them ease of access to adjust the carb.i can see why bsa put them the way the lines are cleaner no fuel pipes showing. But these carbs did not work well on these bikes but the lightning was not a big seller after the lightning rocket had lots of engine issues. When you see pics of these bikes you can see the bikes that are run to the ones that are ornaments. We are miles apart in what we want out of the bikes we have,i am a engineer if I walk down a ally and bang my head on a beam I move the beam not leave as is.as I said late on bsa offered concentric carbs to new owners when they were available. We talk about Chinese crap they have noat to what was coming out of uk factory's in the 60s and 70s

That wasn't the original discussion Mark. The discussion was about how the carbs were fitted to my particular machine and you stated they were not correct - everyone on the call heard you say it mate.
Anyways - it's now resolved and we have had a good natter about it....I'm not even sure now what we are discussing - you seem to have gone off on a tangent. Have a great day my friend.
