    Issue with the engine

    I was riding the bike at around 40 mph on a straight flat road and it was as if someone had thrown an anchor off the bike and the engine seemed to lose all power it only lasted for about a second and has been fine ever since. I don't want to take it to the stealer's unless I absolutely have to. Has anyone on here had a similar issue and if so what was the issue. It was serviced a few months ago and the standard plugs were replaced with irridium plugs.

    Not enough information.

    What has happened is not paying enough attention, grip slips and throttle rolls off. You said it lasted only a second. The what happened, did the bike surge forward and regain its previous speed? If not, I bet your hand loosened its grip otherwise the throttle position remaining the same would cause the bike to surge forward immediately.

    This can also happen if you try to change your hand position when riding at a steady speed. The throttle slips as you try to roll the throttle to maintain speed but change your grip and it seems like the engine just shut off for a second.

    As I said the engine seemed to lose all power and it felt as if the brakes were fully applied it certainly wasn't a roll off and as I ride the DCT it couldn't be an incorrect gear change.

    Hi,
    The standard plugs ARE Iridium. They are fitted OEM.  There is only one plug listed for the CT,  NGK IMR8E-9HES.( there is a Denso listed also but it is Iridium too and ever pricier). So the problem is not with these.
    Cheers
    Tom

    Just trying to help. Unless the engine locked up there isn't enough compression in that motor to cause it to feel as if the brakes were fully applied, that was why I asked if after that second did the bike immediately return to normal speed as it was before this happened. Since you didn't roll off the throttle did engine speed change? If the engine speed remained the same, it isn't an engine problem but could be a driveline problem.

    If it was a momentary driveline problem the transmission would have downshifted.

    If your forward speed slowed as if the brakes were fully applied the transmission would have immediately downshifted and engine speed would have also changed. Upon resuming normal operation, without you changing the throttle position the transmission would have returned to its previous gear selection as forward speed increased.

    Was the transmission in manual or auto mode? 

    There are gaps in the information.
