    try your local Yamaha dealer ... I got them years ago for about $11 each

    If u have the original air filter then wash it in hot soapy water and leave it in the sun to dry ... dont even attempt to change the setup with these carbs

    Yeah original filter was torn up quite bad, even I wasn't willing to give it a second try. Reckon auto barn would have air filters, I forgot to ask as I was excited about getting new plugs haha

    If the original plastic frame is still ok then just pull out the old filter material and get some air filter foam and retro fit it

    airbox rubbers shrinking are an issue - I believe @GreyImport managed to source some new ones and not too bad prices

    They can be treated with Oil of Wintergreen and rubbing alcohol - we had a thread on here somewhere related to it - found it

    https://www.2fiftycc.com/index.php?threads/softening-rubber-carburetor-other-parts.9267/

    @my67xr - recommends dielectric grease, which is worthy of consideration

    Some red rubber grease will make it easier to fit them as they are difficult at the best of times

    Whatever you do, do not use pods, you will quickly go to carburetion hell, perhaps never to return - they are just too fickle

    Don't waste your money or time with pod filters. The airbox rubbers can be gently heated with a hot air gun and stretched over the carbs. The noise sounds like cam chain rattle on the vid.

    I was able to reuse my air filter housing, i cut out the paper element and fit a cut down K&N filter into mine

    Yeah it would work out the same if I just went through my local Yamaha dealer. Just want to run it warm to flush the oil channels before I tear it down to paint the frame.
    Just dropped the oil I put in when I first tried to start to start it and it was black. So got some fresh oil and filter and gotta test the cooling system won't leak before I warm it up and drop the oil again for the tear down.

    Ok, some of the local dealer's don't like dealing with Grey Import bike's

    Yeah I did have to trust some knowledge down his throat but the guy was actually helpful and took his time to learn about what I was asking about. So my dealer is actually quite good and the prices are fair. Other than the $100 air filter he would have to order from over seas other filters were in stock and $ 150 for a chain and sproket kit I thought wasn't too bad.

    You're lucky then, my local dealer think's it's all to hard to do even with part number's, haha

    He needs to find a new job

    You dont buy chains and sprockets from a dealer ... they are aftermarket maintenance parts so theres plenty of places to get them ... even for old shitty grey import bikes

    http://www.rpmmoto.com.au/Store.asp...ufacturer=0&make=Yamaha&model=FZR250&year=all


    Theres 2 things u avoid in the world of old bikes as much as possible ... dealers and mechanics

    The only bike shops any where near me are dealers, I figure chains are about the same online so might as we keep it local and get what I can through them. Even my wife was impressed by the level of attention she got.
    So if I can get the regular servicables ( filters, brake pads ect) from my guy and get what he can't online.

    With a little bit of help, the tear down wasn't as hard as I thought it would be. I was just gonna strip the frame back to bare aluminum and slap a few coats of that clear over it but found a small dent. So I'm thinking fill it and paint daffodil yellow as well as the wheels and do the fairings like a gun metal grey?
    Thoughts?

    Looks like your daughter has it under control, cute. :)
    See if you can find pics with the same colours.

    I would go for a black frame rather than yellow. Or at least not a gloss finish. On my Yamaha I had it done in texture black powdercoat and there is no obvious difference between the cast and the wrought parts. Of course a lot of that would be down to the media blasting that was done prior to paint application.

    Ok what about black frame and arm, grey plastics and instead of the decals like a stenciled sort of style in yellow.
    Something like one of these in yellow would look good I recon.

    Up to you. I don't like to stray too far from OEM, but it is a matter of personal preference. To each their own. Going with your colour choice, I would choose one of the OEM graphic styles or something similar
    [​IMG] [​IMG]
    and use different colours or tones to go with the silver/grey. If you go to my website and look at the carb kit pages for the 250 Yamahas the images are clickable and will scroll through all of the various models and paintwork variations. Some of the 400 pages do the same.

    Could use this style with Gunmetal Grey main colour and Yellow paintout's and black frame and swingarm ?
    Sort of reverse colour's in the pic below, but black is gunmetal

    Here's a 3LN1 full kit in yellow with black paintout's
