My first exposure to correct cigarette paper release from the points. And, no inspirational background noise, or redundant commentary. Thanks for that!
you always inspire me casey- some day will drop into your workshop for a beer but i will carry it them for you- Cheers the pleasure is all mine to see you at work !
I would be lapping sprockets prior to assembly but I suppose if you can clean every bit of grinding paste off it doesn't matter. I love how these books were prior to marker pens, a lot of unnecessary filing going on.
I have a '52 AJS Model 20, I can't find any newer cylinders or pistons for it. Only one cylinder has a cracked baseplate, I am not sure if it can be repaired. Do you know of a good website to source pistons/rings/pinion?
I think, anno 2023 , the way to go is using a digital caliper.......set the caliper at 2 inches or so, have the piston push up the measring rod of the caliper, set it to zero, then push out to 7/16 inch for 39 degrees.....turn the crankshaft and wait till the piston touches the measuring rod again at 7/16 in compression stroke....
Dear Dick, I bought last November precisely this model G80. I learn a lot with your videos! Thank you, you are a very serious mechanic! How can I get the parts to replace? I have no direction, no internet address... Thank you for your help! Pablo
Ciao Pablo, where in the world are you? Many new and used parts can be bought from AMC Classic Spares in the UK. This vendor is very well acquainted with these bikes and a very reliable man. his URL is www.amcclassicspares.com Another good website is the AJS Matchless Owners Club. www.jampot.com// You must join the club to buy parts, however, they are a wonderful resource and a good place to learn. Best wishes, Dick Casey. The RideNut
Mr. Kakade, I appreciate your enthusiasm, however, I can not meet your kind request. I do to own a BSA WM20, and I really prefer to build 'custom' bikes. Sorry!
@@redtobertshateshandles Why would that be? Any engine needs the timing as accurate as it can be. You find it too difficult to rig up a battery, two wires and a bulb? I guess you don't go too far from home.
Bulb across the points on a magneto doesn't work. The mag is independent of the battery, it only generates current in the primary winding when the armature is rotating. Before 1958 when magneto ignition /dynamo charging was replaced by alternator/ coil / battery motorcycle owners did their own maintenance. Their tool kit was often very basic. Dial gauges were a luxury. An experienced man could achieve a high degree of accuracy with the methods shown in this video. Also with manually adjusted advance and retard the timing could be adjusted on the move. By slightly retarding the ignition the rider could improve uphill torque or eliminate preignition. Electric start and Twist and go is a modern phenomenon. Imagine having to deal with hand change gears, fuel and air mixture levers, decompressors and manual ignition control. Add to that before 1930 carbide lighting sets were common and gave a better light than 6V bulbs. The rider needed to constantly adjust the acetylene gas generator while on the move. Stirrup and drum brakes were useless by todays standards leading to brown trouser moments while riding your vintage machine in modern traffic.
Exceptional video, Mr. Casey! Thank you very much for putting this video together as it's one of the best tutorials I have ever seen. Take care!
Thank you Mr. Core!

Awesome, gave me the confidence needed to carry on. Thanks for posting this

Thanks Bill, that pack of Zig Zag is several decades old. Thanks for watching!
What a great tutorial!👍

Mr. Atul, you and your beer are always welcome!
Thank you for your kind words. Ciao DC
I must be some sort of idiot… can’t believe I’ve never seen your videos before,they are fantastic!!! Please keep up the good work 👍
I've timed many mags - I still learned something (as always) from Dick. Great work! Thanks!
Thank you Mr. K, Dick Casey
Easy to understand, very well presented. Thankyou very much.
Ciao Colin, the pleasure was mine. Dick Casey
@@TheRideNut Any chance of a 'jampot' overhaul Dick ? Mine are the early ones with screw rings for the main spring seat. Thanks again, Colin UK.
That's the proper way! Nice work!
Thank you Dave!
Fabulous and ingenious 😀 don’t worry, cameraman was fine 😁👌👍
Full advance when you set it looked like you set piston at full advance?
Thanks casy , you are precious

ok without a degree wheel , but dwell time at tdc is a guesstimate.

Only thing I would be worried about, is jamming the chain against the alloy cover.
this video helped me so much.
Thanks Rubbertank. I'm pleased I was able to help you, DC
That engine looks nothing like the 1954 G80s Matchless I use to have?
Please sir If you have possible then make full restoration video..of these bikes And BSA WM20

@@TheRideNut Respect you sir ! Thanks .
I own a twin but really enjoyed this vid. Thanks for sharing.
Twins are nice too! However, singles steal my heart. Thanks for watching!
Very good video. Your great sir.👍
Thank you Kalim. Thanks for watching!
They are a pain i havnt done it in over 20 years not sure if i had it right then
Ciao Patto, practice makes perfect! Thanks for watching, Dick Casey
Best class ever
Aw shucks... ! Thanls for watching.
Bulb across the points and a degree disc would be more accurate, or a dial gauge directly on the piston.
Cigarette paper is way easier than stuffing around with lights and shit. Close enough for an old chugger like a Commando.

Thanks Casey, Very good video. It would be good to talk to you sometime. Terry Kaas Ritzville, Washington.
Terry I'm on Vashon Island and easy to find. I'd welcome your phone call.
👏 bravo.I have a matchless 500 D year 1933 and I can’t resolve dis problem 😡
Carlos, I'd like to help... describe the problem. Ciao, DC
@@TheRideNut merci,obrigado👍
Maneira exata!
