Mike, congratulations on 100K subs, very well deserved because you put out quality videos and great projects like this one. I'm almost at 100 subscribers and it feels like an achievement that people actually want to watch me! Great news, I've spoken to Ade at AG Engineering and all is well with him. He has been snowed under with the day job. Best wishes, Dean in Oxfordshire, UK.
Loving the idea for this new build Michael! Thanks again for all that you do! We're supposed to get some winter weather tonight here in Ottawa (and apparently you as well), so it will be a good week to work on bikes!
Im really interested in this build not that the others weren't, the reason is I own a B50 totally original except, (I love the phrase totally original "except") it has a CCM 500 motor fitted. I will confess I haven't ridden it ,YET, as it has an electrical issue I have to address. I did inherit the bike from my late brother and believe it or not though disabled and could barely walk it was the last bike he rode and often. He would only ride it to a friends or places where he knew there was someone who could kick start it for him. This was sometimes funny as initially most were younger and looked for the start button therefore needed to be taught how to start it, resulting in most will NEVER EVER own one. What he needed was their weight and physical ability, he had the knowledge.
Mike before going any further think about the steering stops. The puny bracket on the B50 frame will need to be altered to suit the new bottom yoke. Having done a similar job on a B50, I welded tubular stops per the Rickman frames and threw the BSA bit in the bin.
You wonder if had a bit of a crash with the dent in the frame. All of this is really helpful I’ve managed to get a trials 63 Royal Enfield 350 in Clipper frame so going to be re watching your Enfield build again.
Glad you got the forks sorted Mike, the bike will look great when it's finished. Unlike many creators, I know you're not fixated on subscriber numbers, but congrats on 10k subs anyway. It has taken a lot of hard work, commitment & patience to get there.
Good to make a decision and move forwards with the "right" frame. As you were rebuilding the headstock, I thought you might opt for a top nut arrangement instead of the nut, bolt and partially threaded bit that goes in the top yoke. It would have allowed the yokes to be about 1/4" closer together. Thanks Mike.
Always good to spend time in your workshop, but didn’t you hear me? I didn’t make too much noise, because “frame rate versus RPM” but I said quite clearly, “I think your lathe is going forwards, you need it in reverse..”. This is going to be a VERY desirable bike when it’s done... Les in UK
Greetings, You lost me a couple times along the way, but I’m sure it will make sense when I watch it again. Those upper and lower clamps have really fearsome seams on them. Are they cast or forged pieces? I assume you’ll clean them up and make them pretty. You asked in the first video about color scheme. Looking at the factory colors, I like the dark red and black bodywork, with dove gray frame. I don’t care for the purple paint, to 1970s for my taste. When you get to construction of the muffler, I like the shape of the stock muffler. Surely you can make lighter one from alloy. When you do get to muffler construction, can you discuss how size and shape influence exhaust note. A 500cc bike should have a nice, deep tone. Let’s be careful out there. I’m looking forward to the next video.
Nice work as usual Michael I suspect that b50ss frame had been fitted with a triumph twin motor at some point hence the need to cut the cross tube out? Or even to make it a bit easier when fitting a b44 motor and routing the oil feed/return pipes? I know you said you have the matching engine for that frame but why would anyone cut that tube out with the stock motor? Yep people in the UK lust over matching engine frame numbers Got only knows why! I believe a Porsche 911 piston is identical to the b50 apart from the gudgeon pin which is 20mm the BSA 3/4" Cheers
When I fitted the Triumph 350 into the OIF frame to make the TriBSA trials bike I found that you have to modify the front down tube. The split into the two bottom tubes has to start higher up. I did away with the bottom tubes so it didn't matter on that bike.
@@BritanniaMotorcycles According to the book Rolling Thunder, Alan Clews put the footrests on the outer engine cases of his Clews Strokas because he didn't like the through bolt arrangment, although this seems to place them rather too far forward for easy transition from being seated to standing up.
What about a seal for the bearings on the bottom yoke? Forks look great though. Enjoyed the swinging arm straightening methods and felt your pain dropping the nice degree measure, can you buy magnetic ones?
Not sure about the weight difference but the idea was that there was less unsprung weight. After a couple of years all of the trials bikes went back to conventional forks so I suppose they decided that they weren't that much better, if at all.
The very first thing I learned as an apprentice was how to clean parts before assembly. If you do not know enough to clean things, anything further is usless and proves to me that you are not a craftsman.
This is not assembly, this is a fit up to see what goes where, what needs to be fabricated and in fact whether the project is viable at all. If you have watched any of the other builds you will see that nothing is ever "assembled" without a thorough cleaning.

Congratulations on the 10k subscribers - completely deserved. I get so much pleasure from each video - it feels just like dropping in on a friend.

We have around a foot of snow now so it is an afternoon on the tractor for me.

Great work there Michael
I enjoyed the way you worked through all the machining of the front end assembly

Thank you. I remember getting to 100 and being surprised.
Warts and all is why I enjoy this channel :)
its all progress and thats good.
Nice work 👍🇬🇧
Great build as ever Mike, thanks for putting this vid together
Awesome job on the stem Michael
I agree with the caring less about matching frame and engine numbers. The bikes don't know the difference.
Good to make a decision and move forwards with the "right" frame.

Nice work there, Shame about the little axle confusion but it seems all sorted now!

Looking good ,& as per usual another great tutorial

Great videos, very helpful as I'm rebuilding a B25T
Could you tell me what bike the forks are from please?
They are Paoli's from a Scorpa trials bike from the 90s. They were used on a couple of other trials bikes from that period.
Nice work as usual Michael

The bearings have a built in rubber seal.
It's coming on nicely Michael, glad you got the issue with the front forks sorted. Isn't there a spacer/shield washer in the spindle missing?
I fit them in the next video and everything fits as it should.
Always from Bavaria 👍
Thank you Heinrich.
👍👍🏴
👍!
So how do you bore it............. Play Dez O'connor records. (only a few will get that)
I know people like the upsidedown forks and have been told they flex less , but they look so massive do they weigh more than oem and if so how much
Not sure about the weight difference but the idea was that there was less unsprung weight. After a couple of years all of the trials bikes went back to conventional forks so I suppose they decided that they weren't that much better, if at all.
@@BritanniaMotorcycles thanks and keep up the great and interesting works
