    Trophy not running right!

    Rode Trophy back from Smokey Mountains (2300 miles), ran great, and parked it in the garage until now. Started it up & ran alright for a few minutes and then started running on one or two cylinders. Could hear valve lifters hitting loudly and had no power. Any idea what is going on here? :112:

    Hmmm...interesting.  I bought mine brand new last summer with 36 miles on the odo.  Still contained the break in oil as that service wasn't performed until after Thanksgiving.
     Sometime during the fall, after it had been last ridden about a month prior, I started the bike - motor turning over didn't even sound right.  After several attempts it started and sounded/ran as you described. 

    All I could think was 'ain't this a b itch - blown motor on a brand new bike' and just let it run.  After running for about 5 minutes, it began to run-idle properly and accept the throttle inputs.  Has never done it again since - my dealer stated he had never heard of this happening before but do pay attention.  Bike still hasn't turned 800 miles as it gets ridden mostly for short haul errands once or twice a month.  Sounds like a gem and eager to go whenever I start it.

    Do keep us informed.

    It "sounds" like some form of Oil starvation, so check the Oil Level,
    but as the Trophy Valves are not hydraulically operated,
    it could be the Cam Chain Tensioner that is making the noise.

    The Cam Chain Tensioner is presssuried with oil, without which the cam chain will rattle,
    and in severe cases the chain could become detached from the sprocket(s) or jump a cog.

    Have a look at this previous Topic explaining about noise from the Cam Chain Tensioner
    during the first 5 seconds after engine start :

    Not sounding good.

    Also, as with any probem, check ti see if any "DTC's" ( Diagnostic Trouble Codes ) have been stored.
    The process for checking and displaying these ( which does not involve starting the engine )
    can be found here :

    Servicing Data, Reference Info. & DTC ( Fault ) Codes.

    Cheers  :821:

    Just an update on the Trophy
    First I want to thank Sprintst1050 and Coconut for the helpful replies they both sent. Now for the update: Trophy set for a little over a month without being ridden, however I did pull it out of the garage, wash it, and put it back in the garage in about the middle of that idle month (started it and when about 200 feet). Checked the Dtc fault codes and nothing, so I started it up and it ran for 9 minutes before the noise went away and seemed to be running right. My Trophy has 28,000 miles on it and is out of warranty, so needless to say I was worried and still am. Not sure why it was running on only one or two cylinders. If it ever stops raining I am going to take it to the hardware store for a test run. :087:

    I've been suspicious that the "anti drain back valves" in the oil filters fail and the filter empties out.  Start and there's a clatter til the filter refills.  (and the pressure comes up)    Just a theory....

    Might be worth getting compression test/leak down test, had problems with mine which was due to a valve in each cylinder starting to fall apart and not seal correctly. sounds simalr to your symptms.

    Good point I guess, are you using an aftermarket filter by any chance? I generally stick with buying original filters,...I know that K&N ones had a problem leaking due to that poorly welded on nut.

    Yes, I do have a K&N filter, but there is no leaking and it doesn't use any oil, so I think it is alright. I think the problem is the timing chain hydraulic tensioners are bleeding off after time. The bike set in the garage for over a month and temperature at times was probably well over 90 degrees in the garage, summer in Pennsylvania. I am thinking about putting the 50-20 oil in at the next change and maybe that will  help the problem and ride it at least weekly. The bike has been running fine since the problem. The thing, that has puzzled me when I started it that day, it was missing and making a noise that sounded like the tippets hitting.  I think what was going on, was  one cam or maybe both were out of time,  the slack in the chain could move from the tensioner to the area between the cams, which would put the left cam out of time forward. The right cam would stay in time better, because it is linked directly to the crankshaft by the chain, but if the throttle is tweeted they could both end up out of time. This would cause the missing and lack of power. Guys let me know what you think. :112:
