  • 07 R1 engine knock/rattle, suggestions?

    Last night on my ride home from work my bike developed a small knock above 3500rpm at first I cracked the shits and assumed it was a big end but now I am not to sure.

    Heres what I know:
    Bike has 23,000km and has had regular services, the last oil and filter at 20,000 using genuine Yamaha oil/filter
    I checked the valves myself about 2000km ago and all but 2 were within spec so made the adjustments and everything is spot on
    bike has a very good tune, sparkplug were a nice brown colour when I changed them out same time as I done the valves
    There was only a very slight decrease in power on the ride home, but of course soon as I heard the noise I tried to keep rpm as low as possible.

    The knocking sound is very high pitched not like a normal big end knock and speeds up very quickly as you raise the engine rpm, unlike a big end that increases steadily with the rpm. Almost sounds like when u hold a piece of card or something in a fan. Using the old screw driver to the ear method the noise appears to be coming from the timing chain side and above crank height
    Happens both in gear and in neutral (rules out gearbox/clutch issue?)
    noise is not there at all when idling @ 1100rpm and is holding steady smooth idle
    checked the valves this morning and they haven't moved at all
    dropped the oil and there is not even the slightest metallic look to it, if it was big end then there would be fine traces of bearings right?
    Had a look up the exhaust and inlet ports at the valve stems they are as they should be with no signs of leaks or excessive wear
    is not blowing any smoke or any signs of oil in the ports
    I have pulled the timing chain tensioner, stripped and cleaned it then reinstalled as per manual, started bike heard the tension click into place and the noise is still there.


    Can anyone suggest anything else to check while the bike is stripped?
    At this stage I suspect the timing chain tensioner is the issue but I am unsure how to test it off the bike, and given the bike is 90% stripped down at the moment I want to make sure I check any other possible causes b4 I put it back together with a new tensioner.

    This sounds similar to my zx6 race bike, same noise, I had all the cam chain and guides replaced, noise was gone went to the track, jumped a tooth or so and piston to valve, then threw a leg out of bed.

    Although it could also be small end (gudgeon pin) knock ? Hasn't bent a rod slightly ?

    Bent rod will obviously show bearing wear on either side of the shell if you pull the caps off.

      Sell it and buy a honda

      89,000km, no knock.

      (no electrical problems yet either, thanks )


      edit:
      Actually not entirely in jest - there's been a few R1 engine issues reported here over the past couple of years… seems to be the most commonly broken litre bike for some reason :-\
      “Crashing is shit for you, shit for the bike, shit for the mechanics and shit for the set-up,” Checa told me a while back. “It’s a signal that you are heading in the wrong direction. You want to win but crashing is the opposite. It’s like being in France when you want to go to England and when you crash you go to Spain. That way you’ll never get to England!” -- Carlos Checa

        these things I cant really check without opening the motor and I am trying to avoid that at this stage.

                Ha ha, earlier Hondas like my BB commonly developed a sharp tapping/knocking sound when the CCT got worn and that usually starts at ~3500 rpm so I reckon that could bethe issue :insure: Also tend to get slightly more vibration as well, some people equate the CCT noise to marbles in a tin can Never got that bad on mine but it did get a bit noisy @~80k and developed a slight vibration so I changed it out (~$50 from the US) Been good since

                        What sort of mileage are these bikes?...they should be good for better than 23k before blowing any bearing ffs!
