    06 Crf100f wierd sound

    by ldavis » Tue Mar 02, 2021 8:13 am

    After about 4 months of use from the dealership there a wierd noise coming from the engine. I do regular maintenace on it, changing the oil every half month and I dont usually go over maybe 1/4 throttle in fith gear. I think its coming form the cam chain being loose, is this somthing common and can be fixed or am I just being scared.

    Welcome to the site !! \:D/

    It could be the timing chain , or it could be the tensioner itself .... it could also be the clutch ... if you notice the noise , then pull in the clutch (while running) and you notice a difference in sound , but the same kind of sound , it could be the clutch basket rattling ....

    Usually the timing chain stretches after a large amount of time , or if the engine was overheated or run low on oil .....can they just go bad ?? , yes , but it does not sound like you have a bunch of hours on it , so my next guess would be the tensioner itself , they do go bad , and they will allow the timing chain to chatter .... so that is what I would look at first , if the clutch test fails to show anything ......

    There should be 2 adjusters on that bike , one at the back of the cylinder on the shifter side , and the other on the head on the same side , the one on the head is the fine adjustment , so I would try that one first , if the noise stops or changes when you move the screw , then you will know if it is the chain/tensioner , if you adjust it and set it and the noise stays away , then you should be fine ...

    Here is a video that will walk you thru the procedure ...

    Wow thanks JIMDIRT, I really didnt think no one would answer but thanks man. Im going to see if adjusting the tensioner will help because I alreay checked the clutch basket. Thanks for the Video, really helpful. =DD =DD \:D/

    Him JimDirt I tried ajusting the chain but I dont think it did much and if it did it got louder, I saw somwhere that these bike are regularly noisey but I dont think it sopposed to be this loud
