- On the early D1 Bantam, the fork bushes were silver soldered in position, making them very hard to remove and replace. This video shows you a great way of solving the problem...
Many many years ago my father had a BSA Bantam.
This year i bought a 2020 Honda motorbike for commuting to and from work, i like the old bikes but i needed a reliable hassle free commuter, it is not fast ( being a small engine, but very economical ) love the styling of it too!!
Mine too! 😊
Great video Adrian. I've recently started to restore my Dad's old 1951 D1. Your vid has clearly shown me the fork assembly (it came without bushes). I'll certainly be looking at your other videos. Thanks.
Glad you found it useful - and sorry for the VERY late reply. I'll be working on the rest of the Bantam over the winter, so watch this space!
Excellent Adrian, thanks a lot. Very helpful.
Glad you found it useful 😊
I've never had a whole Bantam but I once fitted a D3 engine in a Russian frame from a Regent 125. The Russian engine was based on the same DKW engine design as used for the Bantam but BSA did it as a mirror image, so that the gear lever and kickstart would be on the right. The engine mounting holes lined up perfectly but I did have to modify the rear brake lever to go on the other side of the frame.
Interesting! 😊
Thanks Adrian,
Yes quite interesting. Always great to see good practical ways of overcoming apparent 'difficulties'.
If only we could always become aware of these clever timesaving/far~less~frustrating methods Before some of us begin destroying what we're trying to fix. 😊
My first 'steed' was in fact a venerable Bantam (124cc circa early 1950's?). I think once I worked out that it took me over 100 miles for either a tankful, or one impish gallon.
Those were way back in the primordial early 1960 era, of Lbs, /- and d. (Pounds, shillings and pence).
My powerful machine could hold 3rd gear for at least ten seconds, before needing to go for 2nd, in a strong violent eight mile an hour 10 o'clock 'headwind.
A 9 o'clock one would allow an extra three to five seconds; before the change-down (before it finally came to a stalled standstill ).
And a tailwind of such ferocity would give me anything up to a mile or so!. PS The Australian Riverina around Deniliquin is known for being akin to a billiard table.
🤠
Take care Adrian, and thankyou for sharing these great videos of your exploits into the realms of impossibilities and magic.
Thank you :-)
great advice.
Thanks 😊
My friend has 12 x D1/3 s in parts in his garage, he got them when he was 18 or so, but now 72 and has never got around to it.
Quite a collection. Shame it's going to waste 😕
Since you have a lathe, why didn't you use a boring bar to remove the old bushings?
Mostly because I haven't got a boring bar, or the required skill level to do the job that way. 😁
Induction heater & loctite?
could you not drop the bush in from the top to space them further apart
I'm totally not an expert, but if I had to remove such soldered bush I'd go to guy with good lathe and try to mill it out.
That's a fair point, but not everyone has either the contacts, the money or the equipment to do that. I've ridden, raced and worked on bikes for over 45 years, and sometimes you have to make do with what you have at the time - particularly if your bike is needed for everyday transport. There's a balance to be had between a practical solution & an ideal one. 😊
Adjustable Reamers .
That would work...
Why not just use a full length of brass which is the same length as the bushes and spacer?
Several possible solutions, but this was recommend on a Bantam forum and it worked nicely. I'm more into working solutions than "exactly as it should be" absolutism. 😊
Dear god… a propane blowtorch is enough for silver solder! Or find someone with a lathe and bore them out!! Twatting it with a BFH is NOT the way to do this.
That's fine - if you have a Propane blowtorch... My way worked though 🙂
@@t20racerman using inappropriate tools is no defence. A visit to your local DIY shop would see you equipped for very little money. We’re talking the sort of equipment that’s used for traditional plumbing… nothing more!
Stick it in a lathe and bore it out. Your method sounds more likely to cause damage than success
My method worked though 😊
