    Hi all,

    Have had my brand new Speed.Twin 1200 for two weeks or so I’m really not sure whether it’s running properly. The bike has now covered 350 miles and is quite jerky, sort of on/off if you know what I mean, between say 2200 and 3000 revs, it’s subtle but it’s definitely there. It more noticeable in the lower gears, but it does seem to be present in the higher gears to. Settles down once past the 3k mark. Changing the mode doesn’t seem to make any difference. I noticed the chain had a lot of slack, 55 to 60mm, so I’ve tightened it to around 20 -25mm as per Triumphs recommendations, but that’s made no difference either.

    I don’t recall either of the two ST1200’s (pre and post updates) I’ve ridden previously displaying this, though it is a little while ago. I don’t expect the bike to be as smooth as the inline four I’ve just given up, but this does seem a little to much. Quite disappointed to be honest.

    Does my experience sound normal and they’re all the same? Are there any known issues that I need to explore with the dealer?

    Any thoughts or ideas would be greatly appreciated.

    Regards,

    Andy.

    Thanks for your response.

    I plan to give the throttle spacers a try as I think I’ve noticed the snatching people often refer to. Unfortunately I suspect my main issue is the bike is running too lean once warm, which being a Euro 5 model has a locked ECU.

    Does anyone know whether there’s away around this Euro 5 rubbish?

    Unlike cable operated throttles there is no specific requirement for free play in electronic throttles, however my Speed Triple's electronic throttle twist grip has about 1-2mm free play which appears to be normal and I have no snatchy throttle issues. I would say that if your Speed Twin throttle free play is in excess of 2mm then the plastic spacers mentioned in the previous post would be beneficial. Check out 'The Missenden Flyer' video on Youtube on how to install the spacers on a Speed Twin 1200 for which it does seem to be an issue.

    Although Euro 5 ECUs are more restrictive than Euro 4 (which mine is) I've seen that they can still be accessed and modified. It's pretty irritating that you'll have to extra pay for the privilege of having the bike running well after you've just bought it. You'd be best getting a professional tuner to do the job running it on a dyno, but that won't be cheap. A cheaper alternative would be fitting a (Euro 5 spec) X-pipe.... engine runs a bit cooler and smoother or (cheapest option) running the Adaptiion routine (just in case the dealer didn't do it). Good luck.

    Thanks Higerty,

    Whats the Adaption Routine?

    The Adaption process adjusts the ECU to account for environmental changes, air pressure, temperature, fuel or minor alterations to the fuel system or exhaust. It happens constantly while you are running the motor but sometimes it's good to do a reset, so ECU does a complete adaptation.
    ****At no point touch the throttle****
    Start the engine. Let the motor run (without touching the throttle) until the fan starts running. Wait 12 minutes (time it) shut the engine off. Job done!! It may not make any difference, but it just might!

    Hi Andy, the issue is the Euro 5 emissions regulations, most makes and models now run very lean, an ECU re flash can be done, however my advice would be to stay well clear of doing so, I say this as once the ECU has been modified Triumph will not entertain any claim under warranty, it invalidates it completely. Prior to the re flash the original data is downloaded for re installation should this be needed, however I can assure you that once the dealer plugs the factory test unit in it will show up all the data, and you won't have a leg to stand on, so to speak. There is some good news however, and it will not affect the Triumph warranty, and this is to fit a Rapid Bike Evo Module, here is a little information about it.
    Rapid Bike EVO add-on module puts in your hands total control of fuelling operations as it is directly connected to all stock injectors (up to eight) while managing at the same time the corresponding air/fuel ratio. In this way the fuel values can be modified throughout the entire engine power delivery curve.
    The ability to manage stock lambda sensor signal allows performing the exclusive auto-adaptive feature to secure that fuelling is constantly adjusted while riding the vehicle. The injection map becomes a dynamic value in order to match the changing weather conditions and driving style. This function is highly beneficial at low and medium rpm where the engine performance is poorly limited due to more and more restrictive anti-polluting regulations.
    Rapid Bike EVO supports quick shifter sensor (optional), multiple maps management, raising RPM limiter (up to 1000 rpm) and the elimination of speed limiter.
    For twin cylinders engine equipped with double lambda sensors, it is possible to develop a specific injection map as well as an auto-injection remapping set specific for each cylinder.
    Installing YouTune controller allows to enable and manage additional features:
    REAL TIME MANAGEMENT of additional functions such as modulation of auto-adaptive target for air/fuel ratio calibration, fine tuning of engine braking effects, full customization of quick-shifting, while also displaying a number of engine operating parameters
    ENGINE BRAKE managed while decelerating to prevent rear wheel jumping and improve the bike’s stability while cornering.
    RPM CONTROL ACTIVATION to maintain constant engine power delivery and cruise at smooth and comfortable pace.
    Please see Rapid Bikes bike specific application list for features available for your bike.
    It is easy to install, it does not interfere with the ECU in any way at all, and can be uninstalled should you need to, hence no issue for any warranty claim. Ride safe all from an ageing Rocker.

    Yes my 660 was a bit funny for about the first 500 mils but seems to have settled now.

    Thanks all.

    some good advice there, so thank you very much!

    My bike is now booked in for its first service. I’ve got to wait four weeks time would you believe….

    I’ll get them to have a look when it’s in, though I may try the adaption beforehand if I get chance.

    I’ll let you know how it goes.

    cheers,

    Andy

    Try running it on E5 fuel. Shouldn’t make a difference but I run all my petrol engines on it. E10 is not helping anyone’s engines and fuel Iines, pumps etc…!

    I had a regular stalling issue on mine where the engine would just fluff out if coming down the box too quick. It disappeared after carrying out a hot reset. The cold adaptation idle reset did absolutely nothing to alleviate the problem. Why a hot reset should be more beneficial than a cold one is beyond me, it could be pure coincidence although I’ve carried out hot resets on other 1200 twins and that has also cured minor niggles instead of trying a cold adaptation which could take up to 20mins. It takes less than a minute including removing and replacing the seat to carry out a hot reset with TuneECU.
    It’’s what Triumph dealers carry out (or should) after a service if making changes to anything that affects how the engine runs, be it a simple shim change, sensor or air filter swap. If/when they do this at the dealers you may find the problem disappears.

    I was talking to a Garden equipment repair specialist (lawnmowers, chainsaws etc) and he said you wouldn't believe how many carb diaphragms we get through due to the ethanol in E10 expanding/deforming them.

    Interesting…..

    Can you use TuneECU on Euro5 models. I’d assumed they’re locked so you can’t mess around easily (but the I know absolutely nothing about them )

    As mentioned previously the bike is due it’s first service so hopefully they’ll have a look and do something positive.

    I'd suggest simply going out for a long day's ride! The bike is new, bedding in still. Go and ride 2-300 miles to give it a chance to run in and also for you to adapt and familiarise yourself with the machine. Then see from there...

    I would forget all about messing with tuneecu on a brand new bike, just explain at the service and they can maybe advise you, ask about the throttle spacers too. As said previously get some miles on it, it may improve or you may get used to it.

    In my clubs my many fellow members have the same issue What’s the reason behind this?
