do I have to remove engine to get cylinder barrel and piston out?

[Wayne Cole]

plus, how do I post pictures directly in here? the question is as simple as that, on my 1953 macthless g3l 350 single, can I remove the cylinder barrel and piston etc without taking the engine out? it looks like a squeeze for sure. cheers very much.

short answer yes there is room. Do remember to slide a clean cloth under the barrel before you lift it off in case your problem is the broken piston ring or loose gudgeon pin.

ah that's great news! yeah I have researched so much into this process before I carry it out. took the bike out for a spin yesterday, I realised that I actually have a 4 speed gearbox, sweet! the bike rides really nice, got up to 60 mph and it wanted to do more. you may say if you have an issue with engine I shouldn't be riding it, well I know my issue is not a big one, I listen to the bike I know this is something small. I took out the oil filter from oil tank last night, hahaha the thing was choked to death! even that could be my issue? will take out the gauze in oil pipe under tank tomorrow and soak it in petrol so then I know filters are clean! new carb coming very soon (shout out to classic bike parts Cheshire) those guys are great. sending my dynamo off to a place in uk to get reconditioned, I took chain off for the moment it scared me quite a lot when I actually saw the dynamo out of the bike it was an accident waiting to happen. I'm really glad I am getting a response on here I almost felt a little disheartened at first, look you enthusiast's! you don't get someone more enthusiastic about these kinda bikes than I am right now, it's pure love and I am determined to make this thing good as new eventually. please look at it now, mudguards were removed and dent's taken out and re-painted, primary chain case removed and re-shaped (twice) once after primary chain bounced up and hit the silly inspection hole cover, the metal clasp thing at the back of it, knew then the chain was way too loose so had to learn about moving clutch boxes back! bolts did not want to move so I got a metal rod and sledge hammer and banged it back. anyway here she is, probably my one true love apart from my two year old. cheers clive you sir are a legend, I am now a member.

Looks great. I share your excitement. Those iconic rigids with the low saddle height and the 350's with their wide torque range are a smiley relaxing ride.

A word of caution.
When you refit the dynamo you must ensure that its aligned laterally so that its chain can't clash with the primary chain or its likely to break causing all manner of serious damage.

The dynamo should have an adjustable alignment bracket but check that it's correctly positioned. If there isn't one (many haven't been refitted by PO's) mark the correct alignment position on the dynamo because after you have refitted the primary chaincase you won't be able to see inside to check.

These are the correct nut, lockwasher and circlip for securing the sprocket.......

strange, I would have noticed that but mine is not adjustable?

It could be a home-made one but best to check that it still aligns the chain o.k.

(The magneto HT pick-up carbon brush, spring and the Bakelite holder are still available).

I think it's ok? I'll double check, already had the clutch chain break in case destroying it, somehow managed to get that water tight again? need rubber gasket and band helped a lot. seems I might have a weak mag, spark from plug when resting on cylinder is orange, should be blue right? don't know if I am allowed to place companies here but this company I'm getting my dynamo refurbished also does mags it seems. http://www.vehicle-electrical-rewinds.c ... edback.php is an orange spark responsible for my bad idling I wonder? but again it rides perfectly fine until I stop but it could be a number of things really, carb for a start.
