Martin you need a longer front engine stud with a spacer about 1" long. You can make it out in this engine rebuild picture. 

Ron

Here's mine.  Never fitted a kill switch, I try not to leave my bikes out of site or no one on guard. Ron

PS. Vokes kit includes protector pad. Ron

I think the Vokes were originally Felt. But I use suitable size grommets from "Vintage Supplies" . I have these ones which I think will fit the bill for the Talflow. They have hollows for the feet to sit in. Ron

I've finished the Talflow. I cut some new felt for the filter by using the old manky one as a pattern. I forgot to take a picture before I buttoned it up. I've just got the holding straps to make from a cardboard template.

If anyone is interested, I've now got this good quality repro Vokes, surplus to requirements. The elbow is also repro and the plate is one of the latest from "Vintage Brass Plates" £390. PM me off line is best.   Ron

There were no extra numbers Lex. The top has four coats of high build red oxide now with W&D after each coat. So top coat next.

Calendar just arrived.👍😊  Ron

Mine is a proper WW2 steel headlamp 😜 Ron

Steve, with a tailors tape, center of medallion to front edge of rim is 3 1/2".  Ron

Yes. For dusty places. Like a Vokes tank top filter, but I'd say, not as efficient. Ron

I've stripped the lid and knocked a few dents out. That old red oxide certainly did a good job at preserving these for 78 years. Ron

Indeed Richard, that is one of the M20's Prepared for the India Office. Presumably they were delivered with the Talflows fitted. The MoS ledgers quote that 13,472 air cleaners by Talboys were sent to Indian in 1943. No wonder a small haul has been found. Ron

Ah Ha! It's been pointed out to me that the elbow was not connected directly to the carb. There's a short intermediate  joining tube, which would be extremely hard to find or make. So I'll stick with my plan of fitting it directly to the carb with a different adapter. Same as a Vokes filter.  Ron

Strangely, the screw on carb adapter is far to big for a 276 carb? I measured the thread with a vernier and it's 1/8" too big. So what on Earth carb was it designed for?  I've got another adapter coming which should fit the bill.   Ron

The Talflows tank top air filter was made by the Talboys Manufacturing co. I've just acquired one from a batch that turned up in Pakistan. I've decided to fit it to my M20 just to have something different. The original Vokes on my M20 will be moved to another bike. 

Here is a photographic record of how they were found....A bit bent, twisted and rusted. I've managed to get the four top screws and the three brass adjustable feet undone. I've stripped the base part, knocked some dents out and heat shrunk the base to get it near flat again.  Ron

I did take a picture of my G3L 7/8" Bowden twistgrip components. They're totally different to Amal. The nipple sort of disappears inside a hole. Ron

I don't think I've seen a specific diagram for the panel tank Steve. But you just have to follow the same diagram for a bike with a three position switch.....It's just that the instruments are in the tank and not the headlamp. The only addition is a live and earth for the wandering lead lamp. 

As a tip, I put snap connectors in all these leads and colour coded them....Makes life a bit easier if you have to take the tank off.  Ron 

Hi Rik. Well my crank was finally statically balanced to 56%. But that is with it's heavier than standard weight piston. I wouldn't want to suggest that figure to anyone using a different piston. And of course, different engines resonate differently in different frames, which is why designers adopt a happy medium, and why some bikes suffer from more vibration than their sister bikes.

I'd love to borrow a crank with standard piston that is running smoothly and get the balance facture calculated, just to see what the designers had in mind for these. But it would seem that the usual practice for these type of engines of around 58% would be a good guess. 

Ron

Hallelujah! I managed a 10 miles loop today and I'm chuffed to little tin fittings with the outcome.  The engine smooths right out at 40mph in top gear (30mph in 3rd gear) and stays smooth up to just past 50mph, which is absolutely all I want. 

Next please!!   Ron

Yes it runs nicely Andy, but impossible to tell about vibration through the frame until it's ridden. I found before, that the vibes ironed out at about 50mph. But who wants to ride everywhere at that speed. Ideally I want it to smooth out after 40mph.

Hoping for a dry spell. Ron

It's all up and running now. But as soon as I wheeled it out for a test run, it started raining. I'll try again tomorrow. Ron

It's usually the split skirt pistons that are marked 'FRONT'. The base of the piston skirt is usually oval by a few thousands on an inch when measured with a micrometer. It's the widest part that you use as the datum for the piston to bore skirt clearance. From memory it's .008" for these Triumphs which seems quite a large gap to me. Maybe these Triumph pistons grow when hot? Or maybe they are tapered from the top? I've never thought to measure that!   Ron

My saddle bungie kit from Czech Republic arrived today via Steve. I shortened them enough to give a firm springiness and formed the the hooks to the bare ends. My nose bracket has suffered some abuse by a previous owner, so had to make the best of that. But I'm pleased with the result, especially as I didn't need to remove the saddle from the bike.  Ron👍

That last picture I posted, was in fact a repro MT110. Until the correct MT210 came along. It all takes time. 😊 Ron
