I'm only kidding. Is the original frame that bad then?

There was no frame I managed to get a rusted through rear section and swing arm to help align the motor, the offer of a B50 chassis was there and thought it would make a good combination I had a front end and wheels from my Pantah which were taking up space.

I don't see a problem with this post, aren't we all tinkerers at heart and this is a mighty tinker, if it is too far Stan's are not too far behind but also some of the best.

Being from Yorkshire what I see is a Tax exempt B50 lookalike so yes go for it.
If some of the purists had seen what I have done to a B50/25 OIF to get the seat low enough for a speed record attempt they would cry but our frame was also unloved in the back of some shed and came for free.
Most of the events I race there are a couple of CCMs with XT500 engines fitted, I would rather see B50 engines but at least they are getting used and they still sound the part,

Minety and Rickard,
As Minety has pointed out, it is not his forum. It is Rickard's and it is his decision alone which dictates the answer to the question. Another way to solve the issue would be to start another forum section on "BSA Single Cylinder Hybrids" to allow specials of which at least the motor or the frame is a BSA single.

Of all the forums that I participate in, this is one of the most professional with dedicated forum members. Of late, the project section seems to have waned, probably due to B50s become more scarce, so the hybrid here interests me very much.

I'm fascinated by this project as I had a Yam*h* SRX600 and was unimpressed by the frame, all castings and bolts. I had in mind an Egli type backbone frame, but decided to sell the bike instead. The B50 frame comes close to my thoughts of a backbone design and using the crankcases instead of the bottom tubes is also similar.

From Sam's photographs it looks as if the BSA frame may solve the twin carb issue, too. I never understood why the SRX/XT all had the strange twin carb arrangement, especially as they were two totally different carbs. I toyed with the notion of a single 40mm Mikuni, but it fouled everything in sight on the SRX frame when I tried it.

I'm a keen follower of this topic.

Cheers
Bill

Thanks for the pictures of the tube fabbing process. I like the idea of using a lathe to fish mouth the tubing, I had not thought of that before. Unless everyone else's lathe is different than mine, it doesn't know if the part being machined is for a BSA or Singer. A good mechanical tip or idea is still good, no matter what it was originally used on. Please continue with this topic, I enjoy the heck out of watching someone else's problem solving skills in action.
I was going to say something about people getting their 'jammies in a bunch too easily, but it would be either lost or redundant.

Since you don't seem to have a phobia about slight frame mods, you may want to think about this to solve an oiling problem.

Yes sometime you have to take some, sometime odd or hard, decisions.

This is not one of those decisions.

As there is only the top tube left of the BSA, I will move this topic to " Off Topic " 95 % of the bike will be home made or from some other make.

As some think this is intresting, you will be able to continue to read it where it should be.

I looked at replacing the Pantah discs but at £174 per disc decided against it, I had 300 dia brembo discs and calipers from a Ducati 620 that had only covered 1500 miles so decided to modify the front wheel to accept these.

Machined down the spigot that located the disc

How on earth do you insure something like this? I have just spent a week trying to get insurance for my Lemon. A pretty standard bike but it has a period fairing, the premium doubled because of the "modification" despite my remonstrations that having twin headlamps was safer than standard and being still available from a local manufacturer, would be cheaper and easier to obtain than the original should a claim for a replacement be made. What will you insure it as and when they ask you what modifications you have made, I wonder if the form they send you will be big enough....

When I changed the engine in my B25 to a 5TA I was asked for an engineers report my reply was, 'i am an engineer' (to be honest I was a 17 tear old apprentice at the time) policy given, changed to a 441 victor after a few years nothing asked . I spoke to a friend who built a special and when insuring he was asked for receipts and a value was given on that, I will cross that bridge when it approaches, still a long walk to go yet.

In Colorado the only problem is proving that you own the bike; notarized bill of sale, title search, and a trip to the State Police. They spent a few minutes looking for the VIN number on the headstock before I pointed out that it was on the frame lug. I could have stamped any number I liked on the headstock and titled it as anything I wanted. I'm pretty sure they wouldn't know a BSA from a Y*maha if it wasn't painted on the tank. After that they asked me to turn on the lights and blow the horn and that was it. As far as insurance goes, I just called my company and gave them a VIN number and they said that will be another $75 please. I don't get collision insurance, for pretty obvious reasons.

I have not been able to get near the bike the last few weeks but bought a set of gause filters for Weber stacks and with a little bit of fettling they will work a treat, managed to sand blast the frame last night and fitted the front end this afternoon. Had a wee setback found that the rear wheel had a flat spot in it and the front had a small run off, probably happened when I was hit by a car on the Pantah. The wheels have been sent to Roy Thersby to be straightened so hopefully get them back next week.

I hope you can machine off the "Y*maha" on the side cover and replace it with "Yambsa" or perhaps "BSAmaha."
