CALLING ALL FALCON 67 OWNERS

Post  alan67 on Wed Nov 01, 2017 11:38 am

Hi guys i have a falcon 67 which have had the merlin forks fitted from around the same year as the falcon , that's fine they are the same,apart from the headlight arms. could any of you guys measure for me the arms on your bikes, placing a rule vertically through the center of the bolt that hold the headlight, and then measuring the distance down the top of arm from fork to rule and also the underside of arm from fork to rule, i hope that makes sense, but with this info i think i can fabricate or alter what i've got , any help guys would be much appreciated regards Alan

Hi. I would happily do this to help out but unfortunately my falcon isn't using fb forks. I'm having to buy modern headlight clamps. Good luck with your request

Hello Alan

Have a Falcon 67 myself. In fact just out on it earlier tonight. I've been measuring up the headlight brackets. The length of the headlamp fixing centre to the fork leg is about 3.85 inches, The bracket is about 1 1/2 deep at the root and tapers down to 3/4 where the headlamp is fixed. Its not symmetrical with the distance along the top to the fixing point being about 4 1/4 inches whilst the bottom edge is 3 3/4". Hope this helps. Can send a pattern if any help?
Best wishes
Keith

Please see attached picture. A rolling restoration, rough amd ready. I'm not into as new restorations yet!

Hi Keith thanks for info that's just what i need, with them measurements i can make a card pattern and them make some steel ones i can get the curve from what i have. love the pic of your bike,i'm studying things from it, as to what go's where, i notice on your bike you have a dual seat, my bike has no seat and i am going to fit a single, something like a small lycette although i'm not quite at the stage of fitting the seat yet, when i got this bike there was a heap of rusty bit that came with it and there is a steel base of a dual seat i will see if it fits , thanks again Keith happy riding Regards Alan

To Keith

Great to see a fb on the road. Concourse is not the only way.
A genuine bike being used. Not a trailer bike.

Keep it up

Fun with a 4 speed

Post  keith livingstone on Fri Nov 03, 2017 11:11 pm

Hi Alan
Hopefully the dimensions will get you started an as you say you can tweak it from there. Single saddle looks better
As you'll have seen my differs from original in quite a few areas really just to get it on the road although that was 6 years ago.
See pic of where it started. Someone in the 60's probably chopped the original guard to 'bikini' style. I made the battery case and the rear light cowl. It has Honda 90 lighting switch and an RE turbo twin headlamp / speedo. But it goes well. Recently did 120miles in company of a couple of Honda Pan Europeans and and 750cc Suzuki.

Just finished fettling it with a 4 speed Albion box which I took for a run last night!

Best wishes
Keith

Hi Keith yes that's a project with very little to start from but it's on the road and that's another francis barnett saved love it, yes i think you are right about the seat i'm going to fit a single [ besides i can't see my mrs on the back of this one ] i live on the east coast england and there is a large show around 1st week october francis barnett club has a stand and i was talking to a guy on the stand who had a little sun motorcycle fitted with a 8e and he had just fitted a 4 speed box his experience was a lower ratio between 2nd and 3rd so i guess pillion ridding would be easier as he had a dual seat what do you think after changing your?

Four speed box

Post  keith livingstone on Sat Nov 04, 2017 11:35 am

Hi Alan
It took a bit of time to set up as initially. It kept sticking in 2nd.  First run a couple of nights ago was very promising.
Beautiful sun over here in NI today so hope to get out later.  Old 3 speed boxes are very reliable and forgiving but there a large step between 2nd and top, especially if you are in the hills.  So the extra cog should be the answer.  Lever movement required is very small more like modern boxes but quite stiff.  The only thing I have found so far is that 1st is very low.  Maybe mine has a trials ratio?  Think I'll have to ask the wider community about that.  All the best with your project.  For fun I've attached a pic I found on the web of a similar barn find.

Albion Gearbox

Post  piston 197 on Sat Nov 04, 2017 11:54 am

There is no real way to tell if you have trials ratios fitted other than turning the gearbox sprocket in 1st gear and counting the ratio of turns between the sprocket and the mainshaft, on the tiails gearbox the ratio is 3 to 1, whereas the standard ratio is closer to 2.5 to 1

Originally the wide ratio trials gearboxes had a serial No stamped on the top starting with a "V" and the standard ratio had a serial No. beginning "S", but there could be anything inside now, so this is only a guide these days and best to check the number of turns for the sprocket to mainshaft ratio as mentioned above
