Antony, seems you have quite a friend ... Aside from that, Many of us have made impulsive decisions that provided surprises, so you are not alone. I guess the question is to what extent you have been misled. Not knowing what you paid , it might be that you have a bargain , then again you might have been totally stitched up! What I would say is that contrary to myth there is no real shortage of complete bikes and projects if you want one, so taking a step back, reassess what you want, what your budget is and starting again might be an option before you get sucked into this one so far that there is no way back.

Does the number stamped on the frame match the vin plate ? Any vin plate could end up in a box of spares - it's the number stamped on the frame headstock that will determine where you go from here. As the guys have said, 4l1 means 250Lc, 4l0 is 350Lc, 31k is earlier Pv which is what you should have. You can fit a 350 top end if you definitely want a 350. All depends on what you paid for it and the condition of the rest of it. If you have to find another frame, top end, oil pump etc etc before you start renovating it you may find that more expensive than starting with the right bike in the first place. Restoration isn't cheap I'm afraid. I would mask off the headstock and apply some strong paint stripper to get the coating off neatly, to fully expose the frame number. You can clear lacquer it afterwards to protect the frame, and the number stays visible for MOT, Police etc. If the frame number is legit, then you can apply for a Nova (free), and then an age related plate once it's built and Mot'd.

Worryingly you said the plastics looked like the pic Yogi put up which was a 31k
That vin ain't a 31k

You've either got the basis of a hybrid, LC frame, ypvs motor, or a useless box of bits that are only worth flogging, as you have the wrong frame for the supposed bike you thought you had.

The vin plate matches the number on the frame exactly, so that at least is cosher. Apart from it being german. There are two bottom ends, one with a set of 250 ypvs barrels which is marked 29L on casing and no other marks. There are wheels,exhausts,plastics,seat etc. You may be right. Either give it back and get my money back. Sell it all and start again. Buy another one. ?

29L is Japan spec motor, there are no other numbers to worry about on that score, so you could fit a 350 top end and have a nice lump to fit into the frame, yes you haven't got what you thought it was, but you either build with what you have, although as you have the wrong bodywork, that's extra on top of the rebuild, or you try and get your money back. As "your mate " sold you this, and it wasn't what he told you it was, either he's nit that clued up, or is pulling a fast one, and he's nit a mate at all ....only you can decide that.

What is stamped on pipes: 4L2 or 29L or 51L ? Xavier

The fact the vin plate matches the frame stamping only makes it legit if it's a 250lc frame. If it's a pv frame then it's been restamped, and with the wrong prefix too. What I was hoping was you had an odd vin plate from a 250lc which differed from the frame stamping which should be 31k -. The font of the stamping isn't easy to copy, so unless it looks like the pic Steve - Midlife - posted, then there is a good chance you've got a "ringer". If that's the case, get your money back otherwise you'll be chasing your tail with it Dusty

Unless he wants a original concourse bike, then that's a decent start for a hybrid, maybe a tricker swing arm, and a Athena top end for the ypvs motor
Know what I'd do.

Hi Anthony, so to recap you have been sold: - a 1981 RD250LC 4L1 (non YPVS so) frame modified to have the suspension system of a 1983 YPVS model (first time i see that !!!) with the right fuel tank, plastics, front panel (speedometer...). - a 1985 RD350N/F (1JF/57V) rear arm - a 1980 4L0 RD350LC bottom end - a 1983 29L complete engine from RZ250R '83 (Japanese market model: rd350lc.net/page29L-83.htm (even carburettors are the Japanese model) - for the front fork, the bottom yoke seems to be a '83 or later YPVS model and the top yoke a '85 or later YPVS model but it's not a 1981 RD250LC 4L1 (non YPVS so) - Exhaust pipes could be 4L1 model or RZ250R 29L model, please check the marking as shown here on the rear top of the pipes: rd350lc.net/RD250-350LC%20pipe%20C%20Drawing.jpgSo if you want a RD350 YPVS you will need to buy pistons, cylinders, exhaust pipes, carburettors (or modify setting of the RZ250R but don't know if it's easy)... Is it legal in UK to ride such puzzle ? In France it's not !! Xavier

Well, things are looking more promising You have an Lc frame, so the numbers add up if they are haven't been tampered with. As the guys have said, it's been modified to run with a Ypvs rear swingarm. I had an Lc with that set up; Hybrid rebuild pics (49) by dusty miller, on Flickr Yours looks to have been converted nicely. The double tube at the bottom of the cradle under the engine is the same as what was done on mine, and allows the shock linkage to mount properly (mine was converted by Hejira, so was done well). You gain a stronger swingarm but will lose the ability to fit an airbox unfortunately. Again, Pv yokes are fitted, but you can fit an earlier Pv top yoke to be able to use normal bars. I think you have the basis for a nice hybrid build, if that's what you want to do. The Pv engine will fit straight in that frame if you decide to use it. First thing to do is get a Nova for it - loads of info on here on how to do that. You can do it online too Dusty

You see quite a few like that As for the carbs I would junk them Just rebuilt a 3hm1 that had those carbs and they were a right pain They are power jet carbs anyway so do not go well with pod filters which would have to be used with the monoshock conversion They are also operated by 2 cables which it seems impossible to get the "close" cable This also means the switchgear is different to accommodate 2 cables. Realised that when I tried to fit a 1ua set. It is perfectly legal to build and ride just about anything over here 😀 Steve

Not sure how mine was converted, but it has been to run a vertical shock position, and does still have the airbox fitted

Seriously, you need to decide whether this is a bike for you to ride, or whether you are trying to build an 'authentic' restored investment. You would certainly not be the only person on this forum to be happily zapping around the roads on a 250 frame with a completely different engine. Incidentally, I have owned and ridden a bike with no frame number or VIN at all. It was built from a brand new and unstamped frame. I know because I did it myself. The lack of an engine number is usually a danger sign, but that might be possible too, if a genuine set of cases were bought as spares. There is only one reason for engine numbers to be ground off- crime! It's either the mark of a stolen bike, or an attempt to pass off a rebuild as a 'matching numbers' bike. My advice would be to stop worrying right now. The bike was built long before the rules about SORN etc. came in. Right now it's a box of bits, so does not need any paperwork of officialdom. When it's a bike, then you need to find a way to get it on the road. From experience, it will be about two years before you need to think about that. In the meantime, you have a 350 motor, that would go very nicely in a number of more interesting frames from Aprilia, Spondon, etc. You also have a genuine 250 frame, there are plenty of 250 engines in the world. Two stroke singles from motocross bikes are really good fun! You definitely don't need to cut it up or scrap it.

That PV shock conversion is in my memory bank from a few years back, so unless someone known (NK?) did it and does many like that, its been seen in the last 5-8 years imho.

Hi guys. I've had a word with the guy who sold me this collection of bits. He's going to give me my money back. But he doesn't want the bike back. He hasn't got the time or the inclination to do the build. He has asked me to try and sell it for him. So if any one is interested or has any ideas please let me know. Cheers Anthony
