    Hi guys, well first time out today on my M reg Trophy 900 /3 what a disaster , got about a mile from home, bike started running rough, cut out, fuel and oil pouring out of the bike, seemed to be coming from the air filter box, bike would not restart, when it eventually did, could not selected any gears and it just died again, managed to get it picked up in the back of my van where it remains !!!! Any offers from the faithful out there please !!!!!
    Regards
    Phil

    I'm no expert, but I would guess at dirt in the carbs preventing the float needles shutting the fuel off properly, hence petrol coming out of places that it really shouldn't, and also filling the sump with fuel. So it looks like a carbs off/clean out jobby, followed by an oil and filter change (check oil level on dipstick first). Remove spark plugs before trying to turn the engine over (in case you are thinking of doing such a thing) as it may be hydraulically locked. :eek:

    Others hereabouts may have different/better ideas.

    Hope it's something quick and easy. :)

    Hi Steve, had a quick look this morning after a restless night, removed dip stick and yes full of petrol !!!!
    So I think you were spot on, will start a strip down and get the carbs off, they were only overhauled last year by previous owner !!!!!

    Primary chain? Failing that clutch/gearbox? That's assuming clutch cable and rear chain ok but yer will have checked that I reckon.

    Ouch!
    Just as a final check, make sure the petrol tap is working ok, but if there is no flow of fuel when the engine is off and it flows when it's running, I guess all is well. Had there been any muck in the carbs, it may well now be long gone!
    Can you get any gears by rocking the back wheel with the engine off? If you can find them all, then the gearbox is probably (hopefully!) ok.
    Is there fluid in the clutch master cylinder? :oops:
    Reading between the lines (as written by Haynes!), the pushrod oil seals may have been damaged by the petrol in the oil, as it appears they don't like petrol based fluids! :eek: Might be worth checking them, just in case. Use cable ties to prevent the slave cylinder piston flying across your garden/shed/garage/workshop/town/county in the case of accidental, or indeed deliberate, use of the clutch lever! :oops::eek::mad:
    Obviously this may all be total gibberish, but hey, the truth is out there, somewhere!

    Hi Steve, thanks for reply, there is no petrol tap fitted to the tank it's just seems to be a single pipe atatched from the tank then a t piece feed to the carbs,
    There is fluid to the slave cylinder, have tried putting it into gear and back wheel turns freely as does the chain with no resistance, unsure where I go now, slave cylinder or clutch gone, have got Haynes manual and have tried narrowing it down !!!!!
    Regards

    Hmmm ... I am struggling to understand the lack of a fuel tap. A previous owner's modification perchance?? But it does go a long way to explaining the sump full of petrol. The only things stopping it happening again are the floats and needle valves in the carbs (not what they are designed for!). :eek: For safety's sake I think some sort of tap is needed!
    As for the lack of drive to the rear wheel, I'm beginning to wonder if the gearbox sprocket is securely in place and located properly on the drive shaft. If you decide to have a look, when you take the cover off some oil may be lost as the cover is an integral part of the crankcase. The quantity lost is not vast, (unless the bike is on the sidestand) but forewarned is forearmed, and having put new oil in, you don't want to be losing too much. Keep it clean in that area as well, 'cos you don't want muck getting in to the nice fresh oil.
    Fingers crossed that it is something easy and not a problem deep within the gearbox! :(
    I like a challenge, Phil, but I'm starting to run out of ideas! :oops: Determination still intact though!! :)

    Hi Steve, hope alls well, you are dead right it should have a fuel tap, when I spoke to Triumph they were surprised to say the least that the fuel tap was missing and said its no wonder it dropped fuel in the oil there were only the carb floats holding the fuel at bay !!!!! Good job carbs were overhauled last year bu previous owner no wonder they needed doing !!!!!
    Right so today made a choice, clutch or clutch slave cylinder, went for the latter, removed it, rather old looking and cleaned it up, bleed with fresh fluid a few times to get rid of all the air, tried it in and out of the gears a few time and hey presto got the drive back !!! God knows how it it's going into gears and moving when clutch released!!!!
    So just have to wait for fuel tap to arrive and sort some kind of replacement air filter element, fun and games getting the bloody thing on and off, who would design something like that !!!!
    Any ideas on replacement air filter and thanks for your help and advice and patience with this
    Regards
    Phil

    Excellent news, Phil!! Onward and upwards from here ... we hope!!
    I have a K&N filter in my air box. Yes it is somewhat fiddly, which is why I went down the K&N route - fit and forget to all intents and purposes. The airbox itself is easily damaged - a bit brittle - so be careful with it. Another good reason for the K&N! Sprint Manufacturing, aka triumphparts, can supply new ones (or is it squaredeals aka triumphonline?). Sorry but can't remember the exact websites:oops::(! Both are pretty good for bits and pieces to sort out the older bikes, and indeed some newer ones.
    I'm dead chuffed that you now (almost) seem to have a fully functioning(ish) bike again. Glad you didn't have to attack the gearbox sprocket as well (I was just starting to clutch at straws by then!)!! Another strange piece of design!:eek:
    Good luck with the finishing off bits!:)
