The weather today was brilliant and I set off with Tony at Sparrows fart for a wobble on our Indians. We did a round trip of about 50 miles through the New Forest, calling in at Hurn Flying Club Cafe for doorstep bacon butties.
We then went off to Wimborn to visit a mate, Unfortunately on the last leg home, Tony's bike decided to 'nip up' so I had to ride the last 5-6 miles home alone to bring back the recovery van.
Shame for Tony as pulling the barrels off these is no mean feat 
Mine is the one at the back here at Coy Pond. Ron

No Douglas. Even with plugs out when cold, it was hard to kick over? Something has seriously gone wrong. He's been having problems with the mixture, even after getting the carb overhauled. It's either too lean or much too rich???
At least one of the barrels will have to come off. Not a job we're looking forward to on a freshly rebuilt bike

It must have been quite a sight watching you two pull off and remmember which way round the controls are 
Sorry to hear about Tony's bike, good job he's still got the Enfield for Normandy

Too weak probably, leading to overheating...It's always best to set up rich and then weaken it off as required after it's been run if you are unsure of the correct settings...
If it was rich enough to 'wash' the bores you'd have noticed the black smoke and soot for sure...That, in fact, is an unusual problem..
A double check on the piston to bore clearance would be prudent as well...It's not unknown for them to be done wrong occasionally...Also the ring gaps and clearances...
I have to say timing as well. I would assume you got that correct initially...but something might have moved....
By the sound of it your going to need replacements for one or both pistons... ...Ian

Not too good on the Indian! sorry to hear it! anyway, I'll be delivering the C10 just after Easter, will let you know exactly when, very bizzy now!
Had a good ride out too saturday, for "Operation Quick Anger" crossing of the IJssel river on the 12th of April 1945, (after they shelled Arnhem to smitthereens!) nice wheather, but the G3 made a very loud knocking noise, as if the piston wanted to come out, so took the G3L on the sunday!! first kick after it stood still for more then a year!! was a nice run, from our local tDVMA club, and 6 bikes turned up, of which 4 military! we went to the national Dutch Eenhoorn Treffen, or Unicorn Meet, only for Brit bikes, loads of modern bikes (Triumps) but also some nice old stuff, and about 10 military bikes, M20's, Royal Enfield, etc, some in really weird military colours!
And a 16H "Special" see picture below!
Cheers,
Lex

Yes I agree with your comments Ian. I set the timing with the heads off, to be sure of accuracy.
Martyn machined and rebuilt the carb. Tony complained that it was one click away from being stupidly rich or stupidly weak
I told him to rather run it rich till he sorts the carb problem, but he said it was like having the choke fully closed.
To my mind he was also thrashing the bike a bit too much for a new engine. Or at least it felt like that to me, but then his engine is bored to 600cc with taller gearing than mine.
He's going to have to pull at least one of the barrels for inspection. But these 741's are buggers to work on. They are quite roomy bikes but everything is crammed together. For starters, the engine is not put in the frame More like the frame is built round the engine. There is not room to pull the barrels off under the tank tube. But we have done it by removing the gudgeon pin and lift the barrel with the piston inside it. Real fun to replace though.
I'll take pictures and report back out of interest. Ron
