    I found a brand new set on ebay for my 3LN3, and you can buy them new from Yamaha
    Don't think the 2KR boot's are available new though?

    Have you tried softening them in boiling water, or using a heat gun, then smear them in rubber grease and they can normally be stretched enough to fit.

    Another member here made his own airbox boot's with some reinforced 3 ply Silicon radiator hose with a 48mm i/d.
    Not sure how long they lasted as petrol can eat into normal radiator hose and it doesn't like silicon hose either
    It might be ok as there's not that much fuel/air mix getting blown back out the inlet's ?

    Otherwise you might be able to adapt some off another bike, the 2KR are longer then 3LN3, and are tuned length so you'd need to get the length close too
    Form memory they look close to these, but might be angled a bit ?

    Those outside ones are listed on a few sites as available ... I would try a Yamaha dealer first ... I got my 3LN ones for about $11 each from memory, from a dealer .... use a part number , not the bike model

    I love it when previous owners have the pilot screw done up really tight...

    Wish the 3LN3 airbox boot's were that cheap, mine were about $75 inc post for 4x

    Turns out the crappy paintjob was just layered on top of the original paint! Some light wet sanding brought it back.
    Waiting for more parts to arrive before I continue. Bikes Idling good now and starting easier.

    I wondered why the bike sounded crappy, so I disconnected the coils individually to see if 2&3 were firing, then vice versa with 1&4. Turns out 1&4 were never firing and it was running off two cylinders.

    Trimmed the leads and it sounds way Better!.Of course I messed up the plastic bits that slot over the leads into the coils though.. :sad:

    Oh well, when the front brake reservoir and speedo unit arrives I can take it for a test ride

    No spark this time. Thought I flooded it so I dried the spark plugs, reinstalled, still nothing. Left it two days and still won't fire. it is definitely getting fuel though.
    The plugs look pretty decent, no carbon deposits, just fuel.
    Hmmm...

    On the plus side I got the mount for the front fairing, the Speedo is on, and I got the front brake lever on

    Got both grips, front brake lever(still waiting on the line), head.light, Speedo, dash mount.

    Pretty sure all I need after the stuff I ordered arrives is the fairings, exhaust cables, and the sprocket cover.

    Tfw you leave the fuel tap on over night and your entire tank of fuel is empty but your crankcase has never been more full in its life. BAD.

    Gonna take a wild guess and say the carby needs to be checked out...?

    Take all the plugs out and push the bike in gear with ignition off to pump all the fuel out. Of course you will have to dump the oil and replace.

    Yeah I got it out and replaced the oil, it's kinda horrifying watching (mostly)fuel pour out of the sump plug hahaha

    IMAG0064.jpg IMAG0063.jpg IMAG0066~2.jpg IMAG0058.jpg Got some exup cables from the wreckers, I was missing yet another part, so I made up a little bracket to hold the cables on the exhaust side of things(looks bad but it does the job).

    I never had a working headlight switch as the lever was broken, so I ended up using the end of a spare indicator switch lever, cut it and welded it to the broken headlight switch lever/bracket. So now I can control the lights properly.

    Other than that just small updates, like new(ish) headlight bulbs so high and low beam work on either side, kickstand spring, got the correct overflow bottle and got the chain guards. Probably gonna get the other rear indicator and mounts next week.

    She's coming along!

    The headlight switch was disabled by the people who complianced it before it was registered here, along with a couple of other mod's that made it comply with the Australian Standard's.
    When it goes in for a roadworthy or rego inspection or whatever you have there it may need to be disabled again before they'll pass it ?

    I think that requirement was deleted in the late 1990's. All the late model bikes I've had lately have a light switch.

    definitely coming along nicely, yeah they snapped the light switch off on my zxr as well , ended up fixing it the same way as you :lolsign:. Extending the chain guard is another stupid thing they do to imports which ends up rubbing on the chain when it flexes anyway :headbang:

    My 1990 FZR was complianced in 11/96 in QLD and had the on/off switch removed.
    I thought i read somewhere that the law's changed in 2003 and some Japanese bike's started coming in with on/off switches again

    3 turns out for the each carbs adjustment screw overfuels with the fuel pump near instantly, but without a fuel pump connected it runs for about 10 minutes before dying from lack of fuel.

    Float needles maybe? Might not close due to wear? Thoughts? The fuel pump doesn't continue running though, it primes and fills up then cuts off like it should
