BSA Rocket Three (A75R) Mk 1 - Solving Erratic Running for Mark and Nigel - Part 1 

Beautiful example. Very surprised that junking the horrible Lucas points wasn't priority on this rebuild/restoration.... A must,in my opinion. Great choice of paint and the X75 pipes. Look forward to the next episode.

Beautiful machine. The three on the side pipes look amazing. I wish the new BSA could have given us something to really get excited about like a big retro triple instead of what they served up.

Clive? Top bloke. He told me where I could take a piss after driving from London to Coventry to collect my powder-coated frame and hardware. "Down there behind the shed", he said. He admitted that most of his latter days at Meriden were spent "on strike, lying in the sun." Choke slides on Concentrics or, indeed, Monoblocs are just an added complication. Flooding the carbs on start up via the ticklers is all you need to get the bike fired up, even with a triple where the centre Concentric is fairly inaccessible. Ditch the slides, plug the holes in the carb top, flood the two outer carbs and she'll fire up. Sooner rather than later the centre pot will join in.

Thanks for helping me find the concluding Part " a really interesting thought provoking video, where persiverence and patience paid dividends

A buddy of mine had the Triump version of the BSA, the Trident III. He could never stop the oil leaking around the vavle covers. Got so pissed one time he broke one of the cover bolts trying to stop the leak. Didn't set well with him, he got it fixed and traded it in for a Harley Sportster XLCH. I had a Kawasaki 500 Mach III at the time. We found an open stretch of highway one time and decided to see who had more top end, ended up a tie! But the Mach III would leave him quickly at drag racing from a standing start, or fast roll on at 30-50-70mph. I'm still amazed that we both managed to not get killed.

Looking forward to part 2, what a fantastic looking bike. !

I remember you from the Rocket 3 boards.

Hi guys, i say this most respectfully and I can’t really help meself, so here goes, “we’re only making plans for Nigel “, it’s also my mates name from the late 80s , we worked together,and a favourite song and title of mine… The Hurricane is my all time favourite bike, those colours, the beautiful chrome and those exhaust pipes, like freaking WOW 🤩 guys. I have to say that purple is a favourite colour of mine so needless to say that BSA is beautiful and i wouldn’t turn my nose up if I could afford to buy it, she really is gorgeous. Great video guys and looking forward to seeing the next instalment lol 😂 Ps……if I had an old brit bike I’d have to have an electric rear wheel starter for ease of starting. Pps….it’s also great that you guys can work/mec on the engine.

Great vlog Angus Nice looking bike 👍😎

sounds like you've sorted it Angus as per normal well done.

If you can get it running as well as it looks that will be one fantastic bike. Good luck, sure you'll prevail.

My T160 takes a count of 6 seconds to tickle all three at the same time .cheers

She ran perfect and had an even 500 rpm tickover have since fitted TRI spark

Lucas the prince of darkness😂

The ticklers are obviously not depressing the float........remedy ..1/. check float level settings when carbs are off the bike. 2/. fit tickler extender kits on the outer 2 carbs.Also 1st things 1st.....check cylinder compressions / valve clearances.When running check for vacuum leaks especially at those rubber manifolds & carb base.Finally get rid of those bloody contact sets & fit a Boyer, Trispark or similar system.

hi Angus thanks for your Quick response, well there's something definitely stopping fuel from getting to the float bowls either float hight or sticking float needles but hightly unlikely as you would at least one of the bowls to flood as normal but for some strange thing they are not

Seems like its starved of fuel. Sorry , its easy commenting from the sofa but is the tank vent clear?

interesting... you can buy adjustable floats,,also you can convert the carbs to longer tickler. don't forget to clean and prove the pilot air jets, I have the jet drills if you want, oh and junk the points lol...

My uneducated guess would be dirt in at least 1 of the pilot jets. Good luck 👍

Gold to see that you’re still uploading videos of these fantastic bikes. I only wish the two of you would stand closer to each other when recording with only one microphone.

I hate it when its nothing obvious. Changing the condenser should make a difference, I hope. Also, as the engine has been stood are the valves seating properly and perhaps, the rings are sticking a bit. Just thoughts Angus. I'm looking forward to the next episode because, when its sorted, that will be a cracking Rocket Three.

Love the colour and hurricane pipes produce the best triple sound. 6 years ago I bought a t160 with 375 original miles. The float levels were all over the place. I set up an external fuel level line and adjusted the float needle bush so each carb was set by fuel not float level. Cleaned and cleared pilots make Cleaned points adjusted tappets and she started and ran like a

Love the pipes on the R3...beyond gorgeous. I hope you'll do a full vid on the Fury. I wanted to buy one back in the day. I'm an old fart now but I remember the adverts in various cycle mags for both the Fury and the Bandit. I was fairly gagging to have one. I think that was in 1972 but they pulled the plug before they made more than a handful. Would it have saved Triumph/BSA? We'll never know.

I would love to find one here in Canada to build or ride.

I have just read elsewhere that the lime green bikes were originally intended for the Italian market. I believe only 40 or so lime green bikes were ever produced.

Angus, change the banjo filters as they can look good but wont let the fuel flow.

Where is part 2 of this interesting video

Hello, I've just watched your video and my instinct draws me to those fuel supply lines and those jubilee clips, may I suggest removing those pipes and checking each connection for possible restrictions caused by poor clip position and over tightening. Best wishes. Ian.

LOL Now if you could do something about the oil leaks

hi Angus, the float hights should of been checked as a mater of course before rebuild especially when its showing no fuel at the ticklers, or at least the lenght of the tickler buttons also them amal carbs are well none for the pilot jets to block if lefts for any lenght of time. but if its responding to air screw you as you said it was you might be in luck and they are clear. but my bet is float hights petrol should appear within 10 seconds or there abouts of tickling. good luck Angus i know you'll sort it great vids keep them coming. Ady.
