project RD350 (ypvs)

[st3v3]

My uncle had this stored for about 10years he says in a shed.
He cant touch it now and asked me/my old man to restore it. Dad doesnt have a bike licence (and I still have mine for the moment) I figured why not crack on with it and see what it needs..

Theres bits dotted about in not ideal nick so I need to start building up a list of bits to order.

It has:
Engine
Both Exhausts
Tank
Seat
Rear side fairings
Belly pan

And whatever else is bolted to it.

No idea on model etc, yet to check engine/frame number and send off for v5.
Pics to come later today but what places/forums are good places to use for these?

Bare bike:

Can anyone tell from looking at it of any vital parts missing?

I'd guess the fairing...

[Suntan Sid]

[Asharin]

Chain's slack gone.

[st3v3]

Missing a front sprocket too by the looks of it..

Pretty sure that's with the engine though.

I've got a box full of spares, including a bottom end minus the crank. if you're interested I could crack it out and see exactly what's in it.

That's an F2 Powervalve, engine and frame numbers should match and start 1WT, the barrells will have 1UA stamped by the reed blocks

Getting a bit rare now, there used to be loads around, a mint one can go for over 2 grand, restoring one properly a lot more than that

Really nice bikes, probably the most usable of the powervalves. Engine bits aren't a major problem, just expensive, but finding a decent tank and plastics is a mission I speak from expeience, they can be a money pit

For parts:

RDLCCRAZY https://homepage.ntlworld.com/ultimatelccrazy/

https://yambits.co.uk/

Wemoto are good for consumables

Webbs of Lincoln (speak to Andy in parts) for anything that has to be gen yamaha, he's a wealth of knowledge

https://www.rd350lc.net/pageWORLD-1WT.htm is good for reference

Crank seals etc are not expensive. It is just time consuming splitting the cases but if it were mine I would replace them as the engine is already out. As above, they can lead to a nice bit of wallet damage but are awesome to ride so worth it to restore in my opinion. Why was it taken off the road and stored in the shed?

Change the crank seals, for the minimal outlay it's not worth leaving them, they go hard after a period of time then tear when the engine is running leading to all sorts of water and running problemms.

If there has been moisture in the storing environment then you should really look at a total strip and crank rebuild, any surface rust on the crank pins can kill the big end bearings very quickly, if the end bearing lets go it can take the relevent top end with it, expensive and painful. It's impossible to really know what the crank is like without stripping it, it might feel and look ok from the outside but you can't see the condition of the pins unfortunatly. A crank rebuild is around the 300 quid mark. The mains are not normally too bad, even if it's been standing, but they are not that expensive either.

The rest of the motor should clean up ok by the looks of it, the pics are too small to see any bore damage or major wear, if the pistons are loose in the bores after a good clean up then you could be looking at a rebore and new ones. Mitaka are the best option pricewise. Avoid the really cheap pattern ones, they last five minutes.

You will need to change the powervalve castle seals, they will be knackerd with out a doubt

Right after a scout about in the shed of its storing, I have discovered some parts, saves me buying more.

I was in talks/emails with some sellers of bits but before I order them I'd like to be advised on the chances of recon of the bits I found. (and if anything obvious is missing from the underseat electrics)

Give you £300 to take it off your hands Steve.

You need to stop smearing potato over your lens before taking pictures.

The easiest way to check if the tank is rusted is to put petrol in it and see if it leaks out. If it has been standing empty for decades, then it has probably rusted through.

Likewise the crank is probably rusted. When a 2 stroke engine is standing, at least one port will be open to elements and allow moisture in, which allows bearings and their surfaces to rust. It may start and run, for about 10 miles, then the bearing falls apart and takes the rest of your engine with it.

There is a lot of expensive work involved in putting one of those back on the road after standing for a long time, it isn't just a case of cleaning up the obvious bits and fitting a new battery.

Nice 350YPVS project all the same! It looks like you've got most of the bike there, and with a decent but not OTT resto it could be a really good bike again! I would imagine that one problem with RD's is cash permitting, which way to go with it.

It's common to see people re-build them and go way over the top as they get into it more, and end up with a KR replica, and all the fancy aftermarket bit's they wanted on one back in the day. The other pretty common approach is the OE style restoration where people are spending rediculous money on getting them back to how they looked when new and std.

Personally i think VFM wise a std engine re-build, and clean up and re-paint/power coat of all the cycle parts is a good way to go if you just want to build something up to be reliable and enjoy riding.

If you want it to be worth something or possibly to sell it on at some point, then it's going to be a big expensive project that unless you have the time/commitment and a disproportionate budget, then it's probably best selling on to someone else who wants to do a full resto.

I too think that you could have a running, fairly tidy bike for a grand if you can do pretty much everything on it yourself.

My KMX is probably in a similar condition to that, and i'm hoping to get it re-built in supermoto trim for £2k. I'm pretty sure that i'm not risking painting it myself, seat re-covering or wheel building, so i'm already doubting my budget will definately see it finished? But i'll have a go and save where i can and keep my fingers crossed.

You have to have a realistic expectation and also view of what is economically viable to you? In my case if say £2200-2400 is not enough to complete my project, id rarther sell it as spares and go out and buy a nice road bike for £2k, but if i do that i'll have lost and feel a bit of a failure IMO!

I agree with other's comments of you should definately do an engine re-build on it too. I don't any longer believe that you can leave a 2stroke bike for 10years and it still be possible to get it running and have no engine problems.
