Thank you very much for your comments. Here's a link to the playlist containing videos in this mini-series so far. ru-vid.com/group/PLgDzKiI-i6nahhYPeNGTa1EIiKzOwOy1B
Apologies for 3 separate comments, just remembering things . Another thing that can help , is to slide 'shrink-tape' over the cables (above the carbs ) then when everything is adjusted correctly , pull it down over the adjuster on the carb-top and shrink it in place . Stops water And can help tuning from experience . Sometimes pays to check that the previous person hasn't mismatched the slides to respective carbs also . You have done a great job on these , people underestimate how easy it is to distort them . Dave NZ
I use left over gasoline from the 6 gallon tanks on my boat. It is 50:1 mix using Pennzoil Synthetic 2 stroke marine oil & Premium Gasoline. This keeps my Slide from sticking & the synthetic oil burns clean. I have a 1973 Triumph Tiger with same Carburetor & 63,000 miles.
You can also use a little 'plumbers' thread-tape on gently-tightened threads (soft-carbs etc ) to stop them coming loose, some people use silicon . Both are not visible used sparingly , there's probably a product for it these days , other than lock-tite . Dave NZ
I recently replaced the carb on my 64 Triumph TR6 with the Amal 930 concentric premier. It works great. The removable pilot jet is a nice feature. I've tried the thicker o-ring and some different insulators (for mounting) but it doesn't seem to effect the heat transfer from the engine to the carb. I only recently realized how hot the carb on these bikes get... not so much while I'm out riding, but 20 minutes after I park the bike. It doesn't seem to effect performance, so it's not something I worry about.
Great video, Mike. I hope that people who are using your videos for instruction, especially the carb rebuild videos, can appreciate your incredible attention to detail and soft hand. I have a box of 20 or 30 old Amals I would like to send to you......
Any time I rebuild a concentric I find the slides and or the bodies worn. A new slide helps. Having the bodies bored and the slides sleeved solves many issues. I always install the new stay up float as you can adjust the float level without moving the seat up and down. All stuff I’m sure you know.
Good morning Mike, a pleasure watching you tear the carbs down and suss them out. Reminds me of the Atlas I bought back in the seventies. Never got it together, but it went to a friend who ended up building it back up. I was glorying in my first real money and went through about five bikes in a couple years. Some fine years of riding. It's been a long time since I tore amals apart, and you do an excellent job with such things. I remember all the jets and passages watching you clean them. Sort of wish I had ultrasonic back then. Thanks for sharing this!
Two cups of tea .. 😂 on a 'wet sunday morning' what better job than a 'carb clean' .. nice one Mike. Thanks as always for a through job with detailed information 👍 Have a great week, atvb t ..🏍
Great video Mike. I replaced the Monoblocks on my 67 Lightning with Concentrics also. Made a big difference. They were redone with SS sleeves. Great improvement. Another swap I made on my 70 Commando was a change to a single Mikuni. Ran better and never noticed anything different.
Hey: Mike; what a nice Sunday-morning - video….. by the way: I believe the screws at the cylinderhead are not original; in my opinion there have to be studs…. That is at my T140 Tiger as well…. But anyway, nice video… I enjoy every single one of them! Greetings from northern Germany Manfred
Is there a site for subscribers to put up photo's of their bikes ? ..maybe a 'white-board'/ blackboard or something with a description of specs or changes . I'd love to see a discussion around the TR1-Yamaha (the Vincent-inspired-bike that never made it to the USA ) It's incredible how Vincent led to that entire line of Yamahas (virago's through to Star-liners etc) and influenced ALL the other manufacturers . None of these Old-Classics ever stopped in this respect , they simply laid-the-ground for others . Dave NZ
When trying a part on a granite surface plate with sandpaper you need to go in a figure 8 pattern otherwise you can create a rocker shape rather than flat.
Hello, actually you are using a 360 grit (in some brands is a 320) instead of a 400. That is because P400 (or whatever other number) is coarser than a real 400 grit (sandpaper only says "400") .With Triumph, a thing that you possibly know is that the carburetors have a special thicker O ring and is about 0.060 of clearance when tight.
Excellent as usual. However , I don’t understand as to why there is not an ‘O’ ring on the engine side of each carb spacer. I.e. a groove to take an ’O ‘ ring instead of metal to metal or was a gasket fitted ? Perhaps I am having a senior moment though !
I was wondering that , thought I might have missed the bit where Mike said he put a gasket between the two . There didn't seem like gasket poking out .
Great detail on the filming, can I ask a question? My 1974 norton commando 850, has noise at the top of the heads by the rockers and valves best I can tell, my experience is limited with the noise level being I have never heard another commando live except for mine...I have adjusted .008 on the exhaust and .006 on the intakes but i still hear it. I know it's tough to give advice this way, but is this the norm for nortons...can the adjustments be tweaked at all .oo1 or 2? Either way thanks for all of your videos they are so helpful.
Hi Phil, I would be happy to help. It might be perfectly normal as they do rattle and clank a bit. Yes, you can definitely tweak by a couple of thousandths. Is there any way you could send me a video so that I can listen to it and perhaps share with the guys in the club? You can send a small video file or a link to a Box folder or iCloud photostream to my email address: themightygarage@icloud.com. Good luck! Cheers, Mike
Thanks a lot, Gene. Unfortunately the Shep Atlas project is at a bit of a standstill at the moment while I work on the other bikes and in particular the Manxman. I'm hoping to finish that one first and then will finally get back to poor old Shep! Cheers, Mike
