I will preface all of this by stating that this is going to be my first motorcycle restoration, so please be patient with my utter lack of knowledge. I purchased a 1965 Yamaha YDS3. To my untrained eye, it looks pretty solid. The seat is definitely not original. The only work I have done so far is changing out the Ape-hangers that had been fitted for something a bit closer to what was meant to be on the bike originally. I took it out for a little ride once I had got the throttle to stop sticking, and it ran very nicely for a bike of it’s age- also I’m aware that riding on ancient dry rotted tires was stupid. The good stuff: the tank is very clean on the inside. In fact I have yet to find any rust (other than minor surface oxidation) anywhere on the bike. The speedometer and tach both work and the bike is showing 12k mi and some change. The brakes work, the lights work and it starts up fairly easily and idles nicely. The less good stuff: while all The wiring is working, it seems that a previous owner used a lot of electrical tape to wrap it in places where the original rubber may have been compromised. Obviously it’s not too pretty and isn’t a good long term solution. There are dings and scratches, but that comes with the territory I would think. Also, I am running premix rather than the Autolube system, though it looks like it could function. I was hoping that some of you folks might have some ideas for things I should or shouldn’t do to the bike, on the basis that YDS3s are somewhat rare. I’m a bit torn between trying to restore it and doing some modifications to make it more scrambler-esque. Also is there a good solution for covering the wires in something that isn’t electrical tape? If I’m never planning on running the oil injection, should I remove the Autolube system entirely? Or is that a dumb idea. Thanks in advance for your ideas, time, and tolerance of my ignorance. We all have to start somewhere. View attachment 29665
Hi. To be honest i wouldn't do either , modify or restore it. It's too nice of a bike to modify it. As for restoring it , i'd have a go at cleaning it up first , as in colouring matching the damaged painted areas if possible , especially since it's all original , well nearly anyway. The alloy parts can be cleaned up also by vapour blasting / bead blasting etc.The rims can be re-chromed if there to far gone rust wise and at the same time new spokes laced and the hubs cleaned. But this is only my opinion though.
Welcome J. Dumb questions answered as best we can. Plenty of other Yamaha YDS series rebuilds on here. Have a look in the Yamaha two stroke section and my YDS5 rebuild here. https://2fiftycc.com/index.php?threads/1967-yamaha-ds-5-250cc-rebuild.2185/ As for the wiring I would be using some tubing available from Maelstrom on this forum. He makes the tubing as per what Yamaha used originally. https://2fiftycc.com/index.php?threads/wiring-harness-sheath.9264/ IMO don't modify it as it is only original once, and modified bikes loose value once things are cut up. I would be doing enough to keep it running and on the road and just tidy up/repair the wiring and any bits needed. The oil pump on the -3 is driven by the clutch so when you stop at lights with the clutch in you don't get any oil to the engine which is why most people run premix. I don't like sitting at lights with clutch pulled in as it puts a lot of wear on the bearings and plates and stresses on the cable. Up to you what you do with the oil pump, but if your going to run premix its best to make a blanking plate and remove the pump as it will eventually seize without oil going through it. You have a rare and valuable bike there, enjoy your time with it in your care.
I agree with the others ... it looks pretty original and in as much as photos make bikes look alot better than what they are , it looks like a little renovation more than restoration, and cleaning, will bring it right up to scratch I find this stuff is pretty good for patching up wiring looms as well https://www.ebay.com/itm/3-Rolls-19...192173195596?_trksid=p2349526.m4383.l4275.c10 try this on the chrome https://shop.californiacustom.com.au/index.php?route=product/product&product_id=50
Welcome... nice looking little project there... and I 100% agree on using Purple Metal Polish... it works wonders. Have fun in here... this is far and away THE best bike forum on the planet... lots of technical assistance, 100's of years of experience and knowledge (and that is just in Tamworth ) plus everyone is friendly and a really good bunch of people all with the same sort of passion you have.
Well, I really appreciate your opinion. Thanks for taking the time to respond. thanks so much for all your help. Absolutely tremendous!
Welcome jbach. Nice bike, I would restore it, but it’s your bike. My only advise is seeing as the engine is good, and it has working electrics, ride it as a rolling restoration. Replace the consumables like tyres etc. that make it roadworthy, but don’t rush into big changes. Ride it and see how it feels and looks with a few wash and polish sessions under its belt! When you are out and about on it I’m positive other bikers will come up and chat about your bike, and that will give you food for thought, and your ideas may go in a different direction to what you initially had in mind. Anyway, good luck with it. Bob.
Great bike and lots of people here can help you with it. About the wiring, the sheath that we sell is made by a Japanese company that has a factory here in Thailand. They supply to the motorcycle and car factories here. But some advice about that. You will need to remove the connectors so that you can slide the tubing over the wires (made easier if you use some silicone spray first). These connectors and terminals are often damaged or corroded and it is best to source new ones before beginning the task. Also decide how you are going to fit new terminals and practice on some spare wire. Then when you are confident tackle some small pieces first. Cheers Blair
I have already had someone ask me how much I would take for it. I doubt anyone here would recommend that I sell the bike, but do any of you have any thoughts on actual value? I found valuation estimates to range far too widely for me even have a rough idea. Also, it should be added that I paid very little indeed.
Much appreciated. Unlikely I am going to sell it anytime soon, given that money can be earned but I won’t always be able to find a bike that I like this much.
I tried to get a quote for some tires and the guy immediately deflected towards me selling the bike instead, so I figured I would ask.
Its definately in the 'classic' category especially in its unmolested form http://www.realclassic.co.uk/yamaha_yds3_250.html
You see, you get out and about and people like old bikes! Enjoy giving the bike a new lease on life and riding it. I can imagine if you sold it the chances of finding another in that condition are pretty slim i.e. works pretty much straight off the bat. Enjoy it.
So an interesting correction, according to this serial number, the Yamaha is in fact a 1964 model, if my internet research is correct.
