1941wld asks for a Rickman and a low vin donorbike. What about CB1676 engine 1638? (last 2 ciffers half ditto frame vin!) and a Seeley frame born to take the Sandcast. Though we shoehorned a CBX750 engine into it 25 years ago. Do not really know the diffrence to the Rickman except my Seeley was delivered in black paint to my demand. Am a little shy to let anybody know what bike I´m on. Got a Fireblade in ´96. The Seeley was a match to it up to say 70-80 MPH. Then the stability of the Blade is superior. This on little twisty country roads. But it has not been running for some years now. Friend with an R90S BMW got a VFR Honda. BMW and Seeley were equal on power. A problem might be I do´t know about pictures, and even less how to put them into this forum. Only got one rearwheel. Got new brakeshoes some 10 years ago. O-ring chain was new with the CBX engine. The original sandcast lasted a chain some 1 or 2 K km. The Blade wears out a O-ring chain in some 30 K km. Mileage is not known. Speedo was only on for the autumn 1969 i.e. August-Oktober. Next year the Münch brake of my previous BMW was on for a trip to Italy ordering a 4 shoe Fontana brake. Frontwheel still stands with original 1969 tyre! Speedo shows 6655km. Though now frontwheel is an 18" comestar double disc. In a way I have to sell both at the same time. Some parts will be missing for both to be roadworthy. Have to face the fact I´m but an owner and user certainly not on leavel with what I see in this forum. The engine do turn, I us the the kickstart from time to time. Have a diecast engine for it too. Enlarged to some 8xx cc. A firce cam made it difficult to dial in, so the CBX was an easier choise.
