To be so smart and share this Great gift with all of us on the tube is a wonderful thing. I live in the U.S. But , would some day , Love to have a ride together with the old bikes. Here or there, Agin I say thanks . My 65 would'nt be running now if not for you.!!!!!!!! Cliff

[@TheTwomuchfun]

My Friend, My old bike is running agin. The Break light switch had shorted to Earth.. That is what the drain was from the DC. It started agin the first crank. You're vids are the best. Cliff

Just wanted to say thanks from San Francisco. Used your video to rebuild the Amal on my little Triumph 1971 T-100. Really appreciate your help. Got the brass seat just right, tickler now works and the sucker starts first kick and runs like a top. Thanks again.

Good sir, I just want to sincerely thank you for taking the time to create and post this video. I am a mediocre mechanic at best, but with your help I got my '72 Daytona 500's carbs breathing a lot better! THANK YOU! Any other how-to videos you feel like posting will be most appreciated! - Michael, Wichita, Kansas, USA

[@GarySmythe]

Thank you for the video Lunmad, I'm just at the point of putting my carbs together and was wondering how to set the floats. Your video showed me exactly what I needed.

[@oscarsanchezmendoza2274]

thanks so much for posting this, I learned a lot. I took the carb off my BSA and followed along. appreciate it very much sir.

[@lunmad]

Hi Oscar :-) anytime thank you, I'm glad you are finding my video's useful.

Mate... I have an all original 1973 T140 750 with about 9000 miles on the clock. I originally bought it as a collector piece instead of a daily driver but sitting in the garage with little use and not preserved has taken its toll so I'm in the process of cleaning things and renewing where necessary. I just have to tell you that your videos are exactly what I'm looking for to catch the nuance that the shop manual can't come close to providing. Thanks. Brian (Houston, TX, USA)

When riding for 45 minutes or so at 55 to 60 mph, one of my cylinders will sometimes cut out. It may be fuel related because when I let up on the throttle, the cylinder will start firing again. But after opening the throttle again for a few minutes the problem recurs. Often, the problem clears by itself after a mile or two of driving. If the problem were electric, I it should also happen at low speeds but it occurs only at high speeds (about 3500+ rpm). Thanks for the excellent videos!!

[@grahamtaylor9257]

Hi, I have already used your technique on my TR6, very helpful. Thanks graham, Australia

[@2drosts]

HUUUGE Help!! Thanks for taking the time to post this. My 70 bonnie carbs are bone dry now....no weeping of fuel from the gaskets. Thanks!

[@conhawks]

spent four hours today with plate glass and grinding paste, getting right a timing case off a bsa b44 that had two bad high spots.three hours with course paste and and hour with fine.end result brilliant, all leaks cured

[@lunmad]

@TheTwomuchfun Thank you Cliff for such a great comment :-D I am so pleased and glad my vids help. I would love to ride the states again! only next time I would like to ship my bike instead of hire one. I can but dream, never know I might put the lottery on ;-) Now your is up and running upload a vid for a virtual ride. John

[@jonnightrain]

thanks, doing a 72 tr6r and have fuel problem, sure its float level, fuel poreing out the air box and black smoke you wouldnt believe lucky it ran at all thanks for an informative lesson regards jon

[@nuttop01]

great video sorted out my carb over flowing cheers

[@lunmad]

Hi Nuttop :-) thank you, glad to of helped.

[@shotfirer1972]

hi i have an AMAL carby of a triumph speedway outfit. it is stamped 932 L301 Iwas told it had some history in England but dont know anything else. Its complete and works,(id say the seals would be buggered).It is for a twin and has the original engine intake? Im in Australia. Sorry to bombard you just thought you may know something Cheers!

[@notwocdivad]

@shotfirer1972 Hi there, My mate fitted a Wal Phillips injector to a TriBsa he built years ago, He never did get it dialled in right, It blued a brand new pair of header pipes nearly to the silencer within a mile. (The timing was spot on) So personally I wouldn't waste the time fitting it.

[@lunmad]

Hi Michael :-) glad to help, and if they are helping they are worth the effort! I hope you decided not sell your trusty 500. I think I have about 40 Triumph vids up now, settings differ but the basic lay out is similar. John

[@jonnightrain]

@jonnightrain changed the oil, still a little black thanks for the information

[@shotfirer1972]

@lunmad gday i believe it was off an 850 single carb, thanks for your reply!. I also have a Wal Phillips "injector" that has some history that i'd have to chase up, but its all there apart from the main return spring. Seen many of these on triumphs?

[@UberElectricEagle]

Thanks for the video.

[@mrswinkyuk]

I didn't know Count Arthur Strong had a bike! Great video though, thanks.

[@Katdaddy47]

Any tips for removing the exhaust pipes on a 1950's T100 ?

[@lunmad]

Hi shotfirer1972 :-) your carb sounds like a 32mm left-hand 4stroke carb, 32mm being the bore. I think Norton used these on their 750/850 motors. I cannot see a problem as long as it is jetted for the motor it is on. Although it will work better in the higher rpm range than the lower, this is down to the air velocity through the carb. Not sure what you mean about "seals" but you can get all the parts and kits you need from Amal. ps what Triumph is it? I am assuming it is single carb.

[@lunmad]

@jonnightrain Hi Jon :-) Glad you got it sorted, after flooding problems the oil should also be changed.

[@lunmad]

Hi briank200 It sounds like you may have fuel starvation, there should be four filters, Two in the tank on the taps (suspect) and one inside each banjo. The first thing I would do is undo the banjo's then turn 1 tap on, it should run out full flow through both banjo's, let it run and see if the pressure drops. If its ok, do the same test on the other tap, if the pressure does drop or start sputtering the Tap filters need cleaning. For hi speed running 4-500rpm I turn both taps on.

[@lunmad]

@2drosts Thanks 2d :-) they should be good for another 20yrs now :-D The biggest cause for leaky bowls is over tightening the two screws.

[@Snorky_88]

This video reminds me of the Castellammarese war also it slightly reminds me of my sister cynthia and when she was 5 years old and cut her knee on the street

[@hansraymond1966]

I reckon that it is mostly the same procedure for a Bsa Twin? (an A50 that is.) great video's by the way. :-)

[@transitTrucker]

that grinding paste is 50 years old!

[@Eastsussexbiker]

Yeah mine did too

[@charlieclaw6]

Whenever i have Bonnie trouble......time for Lunmad.

[@lunmad]

Hi rgebishop :-) Glad to help ride safe.

[@hansraymond1966]

I have a Granite plate, can this be used to do this? instead of the glass plate?

[@lunmad]

@Wizbang2u Cheers! wizbang :-) I do me best, a bit slow on the post but get there in the end!

[@massimobarzaghi2566]

Hi, @lunmad what kind of compaund have you used? thanks. Great video!! Massimo

[@dieselscience]

+Massimo Barzaghi It appears to be valve grinding paste.

[@bonkeydollocks1879]

@@dieselscience yea but coarse or fine

[@lunmad]

@TheTwomuchfun Hi Cliff :-) Its great when they start right up. It would be worth going over all the wiring and joints as you have found a "bad" bit. ride safe!

[@lunmad]

@rgebishop Hi rgebishop :-) Glad to help ride safe. I have just worked out how to do these posts :-D

[@lunmad]

Hi quicy0417 :-) I am just getting round to putting the head on, so might just go for a strobing vid, Watch this space :-D

[@lunmad]

@bartimus1515 Hi bartimus :-) Not much to go on there like! ;-) if your timing checks out ok. then it could be an under-size main jet. send us a bit more info and we'll see what I can do for ya!

[@pauljarine]

I'm not the smartest guy; is grinding paste just lapping compound? What do Americans call it?

[@ryandavison.3284]

+Paul Dillon Shit Dillon what are you doing on this thread

[@pauljarine]

+Ryan Davison I don't know trying to learn some stuff...

[@lunmad]

+Paul Dillon Hi Paul yep grinding paste is lapping compound basicly silicon carbide mixed with grease it usually comes in fine or coarse hope this helps.

[@ndspeedster]

4min wasted on watching you sand down the bowl surface.. i think we get the idea after 5 secs... jesus.
