best way to aquire layouts (blueprints) for older bikes that parts are no longer made for ?
I want to help a friend out and make her some parts for her 69 honda super 90. tomorrow I am going to try to contact honda motor company. that is the best I can come up with. I tried searching the net but came up with nothing. bascially if I have some layouts for the parts I can make them from scratch
.. if not I can try and salvage what is left and do some engineering and try to figure out what should be what. I would rather have the layouts though. this would also help me out with the GS as a good starting point to make parts for it.
thanks Josh
Do a little research through the Vintage Japanese Motorcycle Club; odds are good that some of their members can help you to some degree...

That's a tall order to find the blueprints, but with the net, who knows! Hopefully Honda may be able to point you somewhere. They have parts for bikes that go waaaaay back, so it might be easier to buy NOS, unless you want billet aluminum replacement type stuff.
If you can find some fanatics for a particular bike, some of them may have gone to the effort to draw up critical parts.
I'm going to do some of the GS frame with the purpose of assisting my Ezuki project. Sometimes when you want something done, you just gotta pay the time to build the resource.
Good luck!
Makers generally do not release dimensioned drawings and specs` for component parts, it just doesnt happen in Engineering. You might get a line drawing or a GA from them but 99 times out of 100 they will cite copywright and intellectual possesion and knowledge and refuse to give the details. What they are saying is "we have done all the hard work designing and developing the part so buy it of us so we can get some money back in return". They tend to become even more paranoid when its a discontinued part in case you start making them in volume and selling them for profit. This happens in all industries not just mine and I cant see the motorcycle makers behaving any differently. I agree with Cal and Star, try the clubs and find enthusiastic owners. You maybe able to sketch and dimension the parts you need from someone who owns them or even borrow parts as a sample and reverse-engineer them. If they have been made once, they can be made again. Vintage Jap bikes have a huge following here in the UK, there are loads of Specialist Magazines and websites. Do a bit of surfing and I am sure you will find someone who can help you.
