    Hey guys sorry if this has been asked before. I've searched all over Google and done a quick one on the forums too but couldn't find anything.

    I have the double head lights 3ln deltabox frame and wanted to convert to single as my front end was smashed. Does anyone know if the rest of the fairing was the same on both models? And what would need to be changed over? I know the front cowling would, do you think the cowling bracket would as well? I think it came out with two different brackets and not sure which is which.

    The only reason I'm doing it is because I need to replace the whole front end anyway. Fairings, brackets, forks, cluster, lights... So figured might as well change it up a bit.

    Also has anyone had any experience with eBay fairing kits? The $500-ish complete kit. I'm thinking of buying one because all mine are completely totalled.

    Every time I read up on model variations I'm always getting different information so was hoping someone here would have done this conversion already.

    Thanks guys

    I'm pretty certain that the 3LN3 and later headlight cowl will fit on the 3LN1.
    The bracket's are different but the 3LN1 bracket can still be used if you trim the centre vertical brace out,
    mine has had the brace cut at some stage

    Ebay fairing kit's are a cheaper alternative to chasing up replacement oe plastic's, them look like they dont take much work to get them to fit.

    Never tried it but Im guessing its much the same with the mounting bracket

    The problem u will have is the rear bodywork/tail light is different as well from the 3LN1 (which u have) to the later models .....so if u get a fairing kit with the single headlight , it wont match at the back

    Also from the 3LN5 onwards the HP was reduced from 45 to 40 due to Japanese law changes and the redline from 18,500 to 16,500 rpm .... so the clusters are different

    The 3LN1 is a different beast compared to the later models in many ways

    They're actually the same upper fairing stay on the 3LN1 and 3LN3

    Part number 3LN-28356-50-00
    All the 3LN rear side panel's are the same part number just the last 2x digit's are different, i'm pretty sure they just related to the colour and sticker's
    I reckon you could fit a 3LN3 tail light and rear panel to a 3LN1 without an issue if you wanted to

    woah thank you for so many replies! Honestly wasn't expecting so much helpful info.

    I've got the ebay link to the exact image posted above so I'll try and order that bracket tonight. Thank you for clarifying the difference between these brackets on different models. I'm happy to play around and modify it a bit to fit, I just didn't want to have to cut, measure and weld a new bracket to get it on.

    I wasn't to fussed with the back light because I was going to try and modify it a bit. Was contemplating buying the little mustang brake light assembly and fabricating it to fit with what ever provisions my fairings already have. But thanks for letting me know about that anyway, I'll try and get the one for my model but ask if they can switch out the front cowling for the single headlight version. Maybe an ebay seller would be happy to. I was more concerned that the single cowling didn't come out with the delta box frame so it may not have lined up with the rest of the fairings, but going by the diagram above it looks like I should be fine.

    If I get the time I'll try and do a write up on the fairing kit when it comes in so we can all find out if they are cheap and nasty or actually worth the effort.

    Thanks again everyone.

    Kind Regards,

    The 1990 3LN3. and the later 3LN5, 3LN6 and 3LN7 all had the single headlight, some had a single H4 bulb and some had the single light with twin projector's inside and twin bulb's
    All the model's above have the Deltabox frame too.


    Mine has the single light with single H4 bulb

    Your bike looks like it's in really good condition.

    So running with the info everyone has shared, I should be fine using any 3ln fairing just as long as I'm aware of the rear light being different. It looks like the head light bolts onto the cowling so if i go with the single I just need to make sure I order a fairing kit with the single head light cowling and try to get the rear to match my brake light.

    Going to have to replace my forks which have hopefully been posted. Now just have to source a cluster that's designed for the high revving engine, leavers and pegs.

    I've been looking at a lot of stuff from ebay and webike japan, do you guys know of any decent shops or websites that sell parts for these bikes?

    So your bike is a FZR250R 3LN1,
    when you order the new fairing's and want to uddate the look you could just order a complete set of 3LN3/5/6/7 fairing's as they'll fit straight on, some kit's come with windscreen's too.
    Then all you need to do is find a tail light to fit to it.
    A few of our member's have bought and fitted the chinese kit's, if you do a seach you should come up with a few posts/thread's here
    You will need the 3LN1, 3LN3, 3LN5, 3LN6 OR 3LN7 headlight and windscreen (watch out on the windscreen's, some don't fit you need a specific 3LN windscreen)
    It look's like this-

    Windshield-Windscreen-shroud-Fairing-For-Yamaha-FZR250-250-FZR-Big-Ban-3LH-3XH-3HX-1986-1987.jpg


    Otherwise nah there's not a lot available locally, best place i've found is ebay either local or worldwide, or secondhand on gumtree and various facebook group's etc

    Use different searches like fzr250, fzr250r, fzr 250, 3ln, 3ln1 3ln3 etc etc
    There's aliexpress.com for a few new bit's and piece's,
    and japanese auction sites like Jauce and Buyee for original secondhand and some new part's but if you use the latter 2 be prepared to pay a lot for packing, handling and freight etc and some item's cant be shipped like shock's and possibly fork's


    We have a classified's section here and a couple of member's have some FZR part's for sale @Joker, @GreyImport and possibly @Andych may have some bit's you need, also check out @kiffstas' shop in QLD MotoREcycle,
    he has one or maybe 2 3LN's up for wrecking and one bike is listed in the classified here for wrecking from memory too




    What area are you from ?

    Bracket and cowling, that's how they sit, the headlight mount's directly to the fairing only via 4 bolt's

    The dash/mirror mounting bracket only bolt's to the headlight surround fairing through the mirror mount's, so if they line up and the indicator bracket's line up it'll work

    There's another style of headlight that's used on the 3LN3'S and on too, like mine that has a single H4 bulb

    3LN3's should have a dual projector headlight in the one glass piece, if they are as they left the factory at Japan.

    Most of them have a headlight off some other Yamaha model.

    The reason for this is that the ADR specifies a 55/60W globe for headlights. The standard ones are the same as the CBR250 and ZXR250 - 35/60W.

    @GreyImport I think you'll find that the pink lady has 35/60W globes in it, that bike still has its original dual projector headlight

    Whoever imported the bikes made them compliant to the ADR specifications, or didn't, in case of the ZXR and CBR.

    Bracket holes and cowling bolts dont line up at all .... the bottom sections of the front cowling are very different

    That's strange that Megazip has the same part number listed for the 3LN1 and the 3LN3 then ?

    My mistake, the FZR250R catalogue has 2 seperate bracket's listed, 1 for 3LN1 one for 3lLN3, 3LN5, 3LN6 3LN7
    You'll need part number 3LN-28358-50

    Hey guys, thank you again for all the useful information.

    Even though the different cowlings won't fit the same bracket, will the different brackets still line up to my bike frame?

    If I can, ill just buy the cowling bracket off a 3ln3+ and use their faring kit and bolt it all up to my frame if everything will line up. Then I'll only need the head light and cluster which hopefully won't be to hard to come by. The rear light will still be different but I'll have some fun and do a tail tidy and custom rear light.

    Just worried that the front cowling bracket won't actually bolt because it's such a different shape, I think I'll also need to change my intake pipes because they look like a triangle style on the newer models where mines a circle type.

    I'm located in Melbourne :)

    Thanks again for all the info guys.

    @Xavier492 have you looked any further into swapping the cowling bracket's over from 3LN1 and 3LN3 ?
    I know you were wanting to fit the earlier twin headlight's and upper cowl/headlight fairing on to your 3LN3

    I am sure they'd fit

    Just a little update, I've ordered the front head light with the dual globes. I think it is the same one shown above in Greyimports post - 3ln6. I've also order the cowling bracket for the single head light (different one to the one I have) and the forks are on their way. Hopefully I'll have some time in the next couple of weeks to start working on her. I'll be trying to order the fairings next week, so soon I should be able to share some pics of what is a direct swap over and what isn't and what to do to make everything fit.

    Also had a nice chat with some blokes today from where I bought the bracket from. They've all worked on fzr's apparently but they couldn't remember if the bracket was interchangeable with 3ln frames. But they all agreed that all the 3ln frames were very similar if not the same.... So if all goes well should be easy swap over, assuming nothing else is bent out of shape on my bike.

    This is the bracket I bought:
    https://www.ebay.com.au/itm/YAMAHA-...e=STRK:MEBIDX:IT&_trksid=p2057872.m2749.l2649

    and here's the head light:

    That headlight bracket is for 3LN1 twin light
